1. Product Description

4

The DI-EMS 9 Environmental Monitoring System has been designed to incorporate multiple solutions generally developed by multiple companies, into one system. The DI-EMS 9 is an intelligent device that has been pre-configured for a multitude of functions commonly required in Mine Monitoring Systems, but has the ability to be customized for site specific needs and requirements. Calibration of the DI-EMS 9 sensors is usually completed of site by DOUGLAS INTEGRATION, but can be completed on site if preferred by trained technicians.

1.1 General Description

The DI-EMS 9 has four main components that make up the housing: The Cover Plate - The cover plate does exactly what it’s named, it covers the electronic

components from the weather. It has windows laser cut into the face and gorilla

glass secured to the inside to allow the user to view the LED LCD Display, and for

the Full-HD camera to see out. There are also two 1W IR LED modules that allow

the camera to see in the dark, even though the light that they output is not

visible to the human eye, just a faint red glow. The cover plate is secured to the

rest of the system using 12 8mm Stainless Steel bolts around the perimeter. It is

made of 2mm thick steel that has been zinc coated and Powder Coated white

giving it a strong and resistant weatherproof coating.

The Electronics Module

5

- The electronics module ties all of the components that make up the DI-EMS 9

together, including all of the sensors located on the back. It is a 3mm thick

flexible and heat resistant HDPE sheet. Around the perimeter of the sheet is a

film of weatherproof foam that seals the inside of the DI-EMS 9 making it

completely water tight.

The Sensor Cover - The sensor cover sits inside of the tunnel behind the cover plate. It protects

the sensors from any water spray, mud or dust. Each end of the sensor cover

has foam attached to allow air to flow through, but blocks and water spray

and dust, therefore keeping the sensors clean. There is a laser cut rectangle

for the wind velocity sensor to poke through, this cover should only be

removed for maintenance and calibration. It is made of 2mm thick steel that

has been zinc coated and Powder Coated white giving it a strong and resistant

weatherproof coating.

The Wall Plate

- The wall plate is used to secure the DI-EMS 9 to the sidewall of the mine, it

has 4 pre drilled 12mm holes for securing the DI-EMS 9 to the wall using

Dyna-Bolts. There is a slit laser cut down the edge of the plate to secure

cables to, making it look tidy, and keep them from obscuring the wind flow

through the sensor tunnel. It is made of 2mm thick steel that has been zinc

coated and Powder Coated white giving it a strong and resistant

weatherproof coating.

1.2 Interfacing with the DI-EMS 9

6

Connecting to the DI-EMS 9 is as simple as opening a browser on a PC on the same network as the DI-EMS 9. Once you are connected to the DI-EMS 9 web page, you can view all information about the system, and configure the system to site requirements in the settings page. The standard DI-EMS 9 is Ethernet 100mb with PoE support, modifications can be made to the System by DOUGLAS INTEGRATION to convert it to another form of communication, Serial or Phone line for example. This manual assumes Ethernet operation is enabled. For advanced users and system diagnosis, interfacing with the system can be done using WinSCP for file transfer or file editing, PuTTY for service stop/start and system health checks, and TightVNC for remote desktop display of the screen.

*Currently only Google Chrome and Mozilla Firefox are supported

1.3 Operating System

The DI-EMS 9 runs a full 32bit Linux Operating System. This provides the DI-EMS 9 with the ability to interface with many different systems with minimal limitations, if a new interface is needed for RS-485 or serial, a new script is written and installed on the system that enables this. Not only does the DI-EMS 9 run its own web server, which allows it to be a standalone system, but it has the ability to share its collected data to Servers, Other Sensor Stations, Modbus servers and NAS. If required, the DI-EMS 9 can act as a Modbus server for other sensors or PLCs. The heart of the DI-EMS 9 is based around a Cortex ARM a7, Quad Core 900MHZ processor with 1GB of RAM.

7

1.4 Power Requirements

The standard configuration and preferred method for power is PoE (Power over Ethernet). Many switches can provide this, and there are also many aftermarket injectors that can supply this, effectively turning a standard switch into a PoE switch. The system can also be power directly from a 5V source if PoE is not available. Modification to the 4-Pin Deutsch connector will be required to redirect the source power to the main 5V rail instead of the PoE splitter. The system uses approximately 10W of power fully running. The minimum recommended power supply for the DI-EMS 9 is:

- PoE 15W (Standard 802.3af compliant)

- 5V 2.5A direct feed (if no PoE available)

1.5 Local Sensor Capabilities

The DI-EMS 9 base model has the below sensor configuration:

- Dry Bulb Temperature Sensor

- Humidity Sensor

- Wet Bulb Temperature Calculation

- Wind Velocity Sensor

- Full-HD forward facing motion recording camera

8

Additional sensors that can be installed to the Base model upon request, and prior to construction are: - Up to 4 Gas sensors

- 3 Analogue Inputs via 12-way Deutsch connector

- 8 Analogue Outputs via 12-way Deutsch connector

The sensors in the base model are mostly located in behind the sensor cover plate, the exception is the wind velocity sensor which is located in the centermost point between the back plate and cover plate. If there are gas sensors installed, the Temperature Sensor is installed on the outside lower edge of the sensor cover plate, to avoid any temperature differential caused by the heating elements in the Gas sensors.

1.6 External Sensor Capabilities

Upon request, further sensors can be added to the DI-EMS 9, some may require an external mounting plate and power due to space and power requirements:

- Additional Analogue Inputs and Outputs

- Additional Gas Sensors

- Digital Inputs and Outputs

- Dust Monitoring Sensor

These addition sensors can be connected to the DI-EMS 9 via a 12-way Deutsch connector, and once the DI-EMS 9 is programmed to look for and read these additional sensors, they will work just like the local sensors do.

9

2. Mounting the DI-EMS 9

There are some requirements with mounting the DI-EMS 9 that will provide the best accuracy and performance of the system.

2.1 Mounting Location and Best Practice

Finding a suitable location for the DI-EMS 9 requires a Ventilation Engineers report and instructions, but as a general guide, consider the following:

- Mount in a location where minimal wind turbulence will occur:

Mount away from bends or cuddies

If mounting on a bend is required, mount on the outside of the bend

not the inside

Mount away from level accesses or forks in a drive

Mount away from stock piles

Mount on a flat, level surface if possible

Mount on a straight section of a drive for best accuracy

Mount in a location where wind flow will not be obscured by voids,

lumps, electrical boxes and other objects.

2.2 Mounting Requirements

Mounting the DI-EMS 9 requires a hammer drill and 4x 12mm Dyna-Bolts.

10

Find a suitable location on a wall where the DI-EMS 9 can be securely mounted at user level, as flat as possible, to prevent potential warping of the wall plate when tightening the Dyna-Bolts.

3. Cabling

Depending on the variant of DI-EMS 9 you have purchased for your mine, there are a few power options that can be used. Below outlines the variants and specific cabling requirements for each.

3.1 Cabling for PoE

Cabling the DI-EMS 9 with the PoE option can be done simply using a Cat5e or Cat6 Ethernet cable with an rj45 plug on one end, and a DT4 Deutsch plug on the other. As the DI-EMS 9 is only a 100base-T device, we only need to use two twisted pairs to provide power and data over the same cable, due to the minimal traffic required to access and use the DI-EMS 9, even if there were multiple users simultaneously, there is still no need for a 1000base-T connection.

3.2 Cabling for External Power Supply If the DI-EMS 9 requires external power due to no PoE, or no Ethernet (RS485 or

modem) then there will be a two pin DT2 Deutsch socket made available. The

wiring is simple, and the DI-EMS 9 has a regulated supply inside the case which

accepts a wide input range and reverse polarity protection.

DT2 Deutsch 1 – Ground

2 – + 12/24V DC

4. Using the DI-EMS 9 via the Web Interface The DI-EMS 9 features its own web interface, where all of the sensor data, chart

information, calibration dates, settings, live camera feed, and saved data can be

accessed simply using your browser.

To start using the DI-EMS 9, log into it through your browser by going to

http://10.0.0.9/index.php (your IP address may be different if it is not default.)

You will be directed to the home page, where almost all of the information is

available directly, and the rest is available by tabs.

13

4.1 The Web Interface The Home Page is the first page you will see when logging into the DI-EMS 9.

It has been laid out for ease of use and displays all of the information most

users will need at a glance.

Built in to the Home Page, like many of the other pages, is a feature which

automatically reloads the page, it is designed this way so the page can be left

open and no user interaction is required, but it will always display the most

current sensor data.

40005 = O2 (%) (divide by 100)

40006 = CO (PPM) (divide by 100)

40007 = NO2 (PPM) (divide by 100)

16

4.3 Changing the IP address The IP address can be changed using a computer on the same network as the DI-

EMS 9. Open an internet browser and navigate to 10.0.0.9/Settings.php (your IP

Address may be different).

This section will configure the IP address & Network settings

17

To update the Network settings, first edit the text in the text field to the

values you require, for example, change the ’10.90.0.141’ for the IP address

to ’10.90.0.150’. Be careful not to make any errors, after the file is saved and

the device is rebooted, it is irreversible.

Once the changes have been made in the text box, click the ‘Update’ button

next to the text box. This will update the file on the DI-EMS 9.

After the file has been updated, Reboot the device using the button at the

bottom of the page. The DI-EMS 9 will now have the new network settings

after the reboot.

4.4 Changing the Date and Time

The time and date can be changed using a computer on the same network as

the DI-EMS 9. Open an internet browser and navigate to

10.0.0.9/Settings.php (your IP Address may be different).

18

The first step is to edit the Date and Time parameters in the text box. Change

the values that are currently present to the current date and time. Please

note that the time it takes you to physically update the time after inputting

the values with throw out the time. If it takes you 30 seconds to save the file,

and update the time, then set the time parameters to 30 seconds in the

future, so that it reflects the actual time after it is saved.

This section will allow you to update the time after install or power failure.

19

Once the parameters have been changed, save the file to the DI-EMS 9 by

clicking the “Update File’ button. This will save the changes you have just

made.

Once the file is saved, click on the ‘Update Time’ button, this will run a script

to read the time modifications and update the time on the DI-EMS 9. The

timestamp on the live camera feed should change instantly to the new time,

and all Sensor read times should now be current at the next sensor read.

4.5 Setting up Email

This feature is still currently under development in v1.0. The DI-EMS 9 is

capable of sending emails to certain personnel based on alerts and

thresholds, however there is a limited ability to change what is emailed to the

personnel.

We are working hard to update this feature to send reports and data via

email, but currently it will only email a person such as ‘mine control’ when a

trigger or threshold is breached.

As every site is different and in most cases, they use their own email servers,

an email account and port configuration is required for the DI-EMS 9 to send

an email. The steps below will guide you through how to set this up.

20

The email parameters can be changed using a computer on the same network

as the DI-EMS 9. Open an internet browser and navigate to

10.0.0.9/Settings.php (your IP Address may be different).

1. In the text box next to ‘Email address of sensor station’ input the full email

address that has been chosen for the DI-EMS 9, example

This section will allow you to set up the email.

21

‘SensorStation9@douglasintegration.com’. Click the ‘Update File’ button

next to the text box to save the changes. 2. In the text box next to ‘Email address of receiver’ input the email address

of the recipient, example ‘mine.control@douglasintegration.com’. Click

the ‘Update File’ button next to the text box to save the changes. 3. In the text box next to ‘Email Enabled?’ input either ‘yes’ or ‘no’. Changing

to yes will enable the emailing, by default the email is not enabled. Click

the ‘Update File’ button next to the text box to save the changes. 4. In the text box next to ‘Email Server address’ input the server for the email

clients, example ‘pop3.live.com’. Click the ‘Update File’ button next to the

text box to save the changes. 5. In the text box next to ‘Email Password’ input the password for the sensor

station email address, example ‘abcd1234’. Click the ‘Update File’ button

next to the text box to save the changes. 6. In the text box next to ‘Email Server Port’ input the server port, example

‘25’. Click the ‘Update File’ button next to the text box to save the

changes. 7. In the text box next to ‘Email Subject Line’ input the email subject,

example ‘Environmental Monitoring Station 9 has had an event’. Click the

‘Update File’ button next to the text box to save the changes.

The email contents will show all monitored sensors, and it will include the sensor that was triggered or went above a threshold, for example if the Wind velocity fell below 0.5M/S or CO2 went above 0.05%.

22

4.6 Changing the Camera Settings

The DI-EMS 9 includes a FullHD Digital camera with dual 1W IR 640nm LEDs to

illuminate dust particles and view the area. The camera has been included in

the Base model for safety, as it will allow visual inspections or Return Airways

without the need to put personnel in the contaminated air.

The settings can be adjusted on the camera for personal preference of the

colour, image quality and rotation.

The camera by default displays an image of 640x480P as a preview on the

web pages, it is set to automatically start motion recording, and it records

videos at 1280x720P. Higher recording quality can be programmed but it fills

the local storage much faster.

If the SD card does run out of storage space, a script will detect this and start

deleting the oldest recorded videos.

The camera parameters can be changed using a computer on the same

network as the DI-EMS 9. Open an internet browser and navigate to

10.0.0.9/camerasettings.php (your IP Address may be different). Please note

that this web page DOES NOT work in Internet Explorer.

23

Please note that the dual 1W IR LEDs are not designed to illuminate the view

area of the camera, only dust. A light will need to be installed to light the view

area of the camera.

This section will show you the camera preview after the changes.

This section will allow you to modify camera settings.

This section will allow stop motion recording, the camera and manually record video.

24

By adjusting the Camera parameters you can get a clearer image of a darker

object or set the exposure mode to a certain type of lighting condition to

minimise flicker or overcompensation.

4.7 Calibration Date and Schedule The Calibration date for the sensors can be seen on the main page next to the

appropriate sensor, under the ‘calibrated’ text. Down the bottom of the main

home page, there is a ‘calibration’ section, this section will tell you the last

calibration date and the next calibration date for service of the sensors.

It is important to adhere to the calibration and service schedule for multiple

reasons:

1- The gas sensors degrade over time, and the compensation needs to be

adjusted to reflect true readings.

2- Dust build up on the filter pads can affect the gas response times,

especially in high humidity levels.

3- Dust and mud build up on the wind velocity sensor can affect the response

and detection levels.

4- The warranty will be void for the sensors if the service schedule is not

adhered to.

Calibration for the gas sensors are performed every 6 months. The CO2 NDIR gas detector has a lifetime of 5 years before replacement is required, and the Chemical gas detectors have a lifetime of 2 years.

25

4.8 Viewing Sensor Information

The data retrieved from each sensor is all displayed on the DI-EMS 9 homepage.

However if more information is required, such as the last days worth of data, this

can be viewed on the sensors own page, which is grouped based on the sensor

type.

If you wish to view the Wind Velocity Sensor in more detail, simply click on the

‘Wind Velocity’ link on the right hand side of the homepage. It will take you to

the Wind Velocity Sensor page and show you the current readings, and the chart

data since midnight the night before.

If you hover the mouse over a part of the chart on the data line, a pop up will

appear informing you of the time and value at that particular point.

If you wish to view in greater detail a particular event or time, click and drag over

the area of the chart you want to expand, and the area you selected will fill the

chart. This zoom can be reset by a button that appears in the top right corner of

the chart.

If there are multiple sensor values on a chart and it is difficult to read, simply

click on the sensors that you do not wish to be displayed to the right of the chart,

and the chart information for that sensor will disappear. To bring that sensors

information back up, simply click it again.

26

As some of the pages automatically refresh every 2 minutes to display the last

sensor read, the chart will also refresh, if you are zoomed in or have some

sensors hidden, they will reset also.

27

4.9 Changing DI-EMS 9 Location To change the location of the DI-EMS 9 to make it easy to identify where it is

installed, navigate to the settings page and in the text box next to ‘Device

Location’ insert the physical location the DI-EMS 9 is installed. For example if

it is in the fuel bay, place ‘Fuel Bay’ in the text box. To save the changes, click

the ‘Update’ button next to the text box.

This section will allow you to change the location of the DI-EMS 9.

28

4.10 Changing Cross Sectional Dimensions and Drive Offset To change the M/S Cubes calculation for the Wind Velocity sensor you can

modify the Drive height and Drive width for the DI-EMS 9 location, you will

need to measure the Drive width and height and input the measurements in

Metres in the text box. To save the changed click the ‘Update’ button next to

each text box.

There is an Offset feature for the Wind Velocity sensor for if the DI-EMS 9 is

installed in a drive with turbulent wind, or if it is on the inside or outside of a

curve.

For example, if the DI-EMS 9 is installed on a sweeping bend, and the average

M/S in the drive is 10.0 M/S but the point readings on the inside of the bend

is 9.0 M/S and on the outside it is 11.0 M/S, Then the Drive Offset will need to

be set to a value of 1.1 if it is installed on the Inside, of the bend, and 0.9 if it

is installed on the Outside of the bend. This Offset will then adjust the

average M/S to reflect the true readings of the drive compared to the actual

readings at the installation location.

If the DI-EMS 9 Location is changed, then the Ventilation Engineer will have to

measure the readings at the new location and adjust the Offset and Drive

Width and Height again to compensate. This is a known limitation of a point

sensor compared to a cross sectional sensor such as an Ultrasonic sensor.

29

This section will allow you to change the dimensions and offset for the drive.

30

4.11 Changing the Annotation on the Camera The annotation is the text displayed on the camera’s recorded video, it is also

displayed on the preview of the camera. To modify the text being displayed,

navigate to the settings page on the DI-EMS 9.

Annotation – The text displayed in the preview and recorded video.

Size – Default size is 50. The text size of the annotation.

Background – Turn on if the text is hard to read.

Text Colour – Enable to change the annotation text colour.

Background colour – Enable to change the background colour.

This section will allow you to change the Location and text that is saved in the recorded video.

31

4.12 Viewing the IO status and Control

The DI-EMS 9 is capable of Analogue & Digital Input and Output. The base model includes a 12 pin Deutsch Connector configured for Analogue Input & Output, If Digital IO is required, please contact DOUGLAS INTEGTRATION to have this feature enabled and wired to another connector. The Analogue IO is able to be seen on the home page, but it also has its own page, in your browser, navigate to 10.0.0.9/iocontrol.php (your IP address may be different). This page will show you some basic information including the voltage related to the Analogue status of both the Inputs and Outputs, and whether these controls are enabled. Currently the base model is configured to output its Wind Velocity and Gas Sensor voltages on the Analogue outputs, and read the Analogue inputs, however the information is not used in the DI-EMS 9 unless required by the site. Below is the Pin out for the 12 pin Analogue IO Deutsch connector.

If the Di-EMS 9 has had Digital control enabled, then the controls can be set on or off, or to Automatic by the web page. This feature is normally only used if Modbus is not an option, or manual override is required (for example, a secondary ventilation fan needs to be turned on after a blast for 5 minutes). The Automatic feature will run a pre-configured script that must be programmed for its function by DOUGLAS INTEGRATION. For example, the script for output 1 can be configured to turn a fan on if the humidity goes above 80% in a level, and back off when it falls below 70%

This section shows you the Digital Input and Output capabilities of the DI-EMS 9. It is not enabled in the base model.

This section shows you the Analogue Input and Output status and voltage.

33

4.13 Sensor Status Indicator

The DI-EMS 9 constantly monitors the status of each sensor, and it is gets a reading it doesn’t like, it will notify you by email (if configured) and by the status indicator on the home screen and sensor pages. There are 3 status groups that the DI-EMS 9 will notify the user by: OK – The sensor is running as expected and there are no issues. CALIBRATE – The sensor is running, but the reading may not be accurate. ERROR – There is an issue with the sensor. Maintenance is required.

This section shows you the current status of the specific sensor.

34

4.14 Manual Data Compression for Download If you wish to download the daily backup for the sensor data, and need it to

be current, navigate to the settings page and scroll to the bottom, there is a

button labelled ‘Compress Chart Data’ and click this, it will force a backup of

the sensor data and overwrite the current daily backup.

The DI-EMS 9 will automatically backup the sensor data every 30 minutes.

This button will force a data compression.

35

5. Connecting to the DI-EMS 9 via PuTTY or WinSCP In some cases it may be required to view the CPU usage, temperature and to see

if a script is running. This can be done using remote terminal programs like PuTTY

or WinSCP.

For both WinSCP and PuTTY, use the following credentials and port:

IP Address: unit specific

Port: 5547

Username: User

Password: DI-EMS 9

Some useful PuTTY commands:

top – to view CPU load and services that are running

df –h – to view the free disk space

ls –a – to view all files in the User folder

The only folder accessible for the User account in WinSCP is /home/user/ for

security reasons. All files can be manually edited here instead of on the web

page if you need to.

36

6. Retrieving Archived Data Compressed sensor data can be retrieved from the DI-EMS 9 from the

‘Compressed Chart Data’ page. On the page there will be a list of a daily

compressed file, the file is named so that the oldest data is at the top, and the

newest data is at the bottom of the page. If you wish to download a particular

day’s compressed data, simply click on the file and then select ‘download file’.

The data can be extracted using most file extractors, once extracted the data is in

.txt format. You do not need any special software to view the chart data, just a

DI-EMS 9 on the same network as your computer.

This is the list of all compressed data stored on the DI-EMS 9. By clicking on one, you can download it to your computer.

37

6.1 Retrieving Motion Recorded Video To view and download recorded videos from the DI-EMS 9, navigate to

‘Recorded Videos’ web page from any page by clicking the link at the bottom

right hand side.

On this page you can view the recorded video by clicking on the video with

the timestamp you want, a video will start playing on the page, and if it is the

one you wish to download, simply click the ‘download’ button under the

video. It will save as a .mp4 file and can be viewed in windows media player.

38

6.2 Viewing Compressed Sensor Data Once you have extracted the chart data from the ‘Compressed Chart Data’

page that you want to view, go to the ‘Archived Chart Review’ web page on

the DI-EMS 9. This page DOES NOT work in Internet Explorer.

On this page you will see at the bottom of the page a box labelled ‘Drop files

to upload’ where you can add files to the DI-EMS 9 to review. Within your

operating system, select all of the extracted chart files that you have

previously extracted. With your mouse, drag all of the selected files into the

box labelled ‘Drop files to upload’.

All of the files that were dropped in the box will get uploaded and should

have a green tick on the icon. If the green tick does not appear and a red

cross appears instead, try again. If it still does not upload, try each file

individually, as some versions of Chrome and Firefox may have issues with the

upload process.

Once all of the files have been uploaded, refresh the web page. The data

should now show in the two charts.

39

The uploaded data will be displayed in these charts after a page refresh.

Drop files into this box to upload them for review.

What uploaded files look like after completion.

40

7. Turning Off or Rebooting the System On occasion the DI-EMS 9 will need to be shut down for maintenance or for

development. The below instructions will guide you through each process for the

correct procedure so there is no chance of SD Card corruption or data loss.

7.1 Rebooting the System If a system reboot is required, navigate to the ‘settings’ page. At the bottom

of the page there is a button labelled ‘Reboot’, click on this button.

There is a script on the DI-EMS 9 that will detect the system shutting down

and automatically back up and save the most recent sensor data so no data is

lost. Once the system is back up and running, the script will extract the data

again, as though the device was never turned off.

7.2 Turning Off for Maintenance If a system shutdown is required for the DI-EMS 9 to be unplugged for any

reason including calibration and repairs, then a proper shutdown procedure

must be followed in order to prevent any data loss or SD Card corruption.

Navigate to the ‘settings’ page. At the bottom of the page there is a button

labelled ‘Shutdown’, click on this button.

There is a script on the DI-EMS 9 that will detect the system shutting down

and automatically back up and save the most recent sensor data so no data is

lost. Once the system is back up and running, the script will extract the data

again, as though the device was never turned off.

Please allow approximately 1 minute before unplugging the DI-EMS 9 after

clicking the shutdown button.

7.3 Safe Practices of Power Cycling If the DI-EMS 9 has become unresponsive, and you cannot safely shut down

the DI-EMS 9. Then you can unplug the DI-EMS 9 from its power source,

effectively giving it a ‘hard’ reset.

This method of rebooting is not preferred and has the potential to lose

important data saved on the DI-EMS 9 locally, or corrupt the SD Card

completely.

In order to prevent Corruption as much as possible, please do not pull the

power within the first minute of the DI-EMS 9 being plugged in, as it is loading

and writing important system information.

8. Modbus TCP/IP The DI-EMS 9 is set up to automatically act as a Modbus Server. In order for the

Modbus Client to read information, it simply has to connect to the DI-EMS 9 IP

address and port 502 (default for Modbus). The sensor data can be read at the

following locations:

42

40000 = Dry Bulb Temperature (divide by 100)

40001 = Wet Bulb Temperature (divide by 100)

40002 = Humidity (divide by 100)

40003 = Wind Velocity (divide by 100)

40004 = CO2 (%) (divide by 100)

40005 = O2 (%) (divide by 100)

40006 = CO (PPM) (divide by 100)

40007 = NO2 (PPM) (divide by 100)

DOUGLAS INTEGRATION is currently working on a new software version to

customise the Modbus settings and allow output control via Modbus.

9. Local Display The DI-EMS 9 has a local LED LCD display so all of the sensor information can be

seen locally at the device. The screen will rotate through the different sensor

groups automatically every 10 seconds.

10. Upgrading the DI-EMS 9 DOUGLAS INTEGRATION is currently upgrading the software to allow upgrading

the DI-EMS 9 through the web page. Currently any upgrades will be made when

the device is send back to DOUGLAS INTEGRATION for calibration or repairs.
