2. Overview: Interface Board and iSYS-6003

The interface board serves for two purposes:

• It powers the sensor via the 12V power supply (cable included)

• It provides two standard interfaces for communication (USB or RS-485) with the customer

PC

• A 4mA – 20mA current interface has been included as an alternative for providing

measurement results

Devices on the interface board that are not explained in this document serve for debugging /

programming of the iSYS-6003 and are not needed by the customer.

The interface board:

Switch USB (RS232), RS485

communication

Connector USB

3. Demonstration Kit – first steps (for use with USB)

These steps help you to set up the iSYS-6003 demonstration kit easily and evaluate first

measurements with the software package “iSYS-6003 GUI”.

a. Download all available resources for the iSYS-6003 demonstration kit

The iSYS-6003 demonstration kit consists - alongside the hardware in front of you - of the

software package “iSYS-6003 GUI” for visualization of the sensor data and of various

documents / application notes.

This software and documentation can be downloaded from:

http://www.innosent.de/services/downloads/downloads-software/

b. Hardware Setup

In the hardware setup section all steps necessary to set up the demonstration kit

hardware are explained.

• Please connect iSYS-6003 demonstration kit hardware and power supply unit

• Make sure power supply unit is set to 12V



• Connect power supply unit to socket and check LED “power supply polarity”, LED

“power supply” and “LED “boot complete“

LEDs “Output 1-3” may shine or not depending on the firmware revision. That is

not important.

Troubleshooting:

1) LED “power supply polarity” shines orange

Solution:

Please reverse polarity on the connector “power supply 12V”

2) LED “boot complete” does not shine green after a few seconds

Arrow points at 12V

LEDs shine green After a few seconds,

LED “boot complete”

shines green

LED “power supply

polarity” shines orange

Connector “power

supply 12V



Solution:

Probably, the FPC Cable is not connected correctly to the Connector iSYS-

6003. (This can happen at the interface board or the iSYS-6003.)

- First, unplug power supply from the socket!

- Then open the interlock:

- Place FPC cable to the connector and (after that) lock the interlock:

• Select USB for communication

The USB communication is implemented with the device CP2102 (UART to USB

bridge) from Silicon Labs. The iSYS-6003 offers the measurement data via UART

to the interface board. There, the data stream is converted to USB or RS-485.

• Connect the USB cable to the interface board and your PC

Switch that selects USB or

RS-485 for communication

LED “USB selected” indicates

that USB has been selected

CP 2102 UART to USB bridge

LED “USB cable connected”

indicates that the interface

board and the customer PC

has been connected.



c. Software Setup

• Install driver for Silicon Labs CP2102

Please download the latest USB driver for the CP2102 from

https://www.silabs.com. When you search for “cp2102 usb driver” on their

website, the first result leads you directly to the download page. Make sure that

the driver you have downloaded fits to your operating system (e.g. Windows 7).

The driver needs to be unzipped after downloading and installed on your system.

(You probably need administration rights to do that.)

The USB connection will be a virtual com port on your PC. You can check in the

devices manager (for Windows as operating system), whether the installation

was successful:

• Install the "iSYS-6003 GUI”

For quick access to the iSYS-6003 measurement results and for graphical

visualization the software package “iSYS-6003 GUI” has been developed.

Please select the file “iSYS6003_GUI.exe” from the downloaded folder and

execute it:

The COM Port number

can be different from

this, depending on your

system.



4. Using the iSYS-6003 GUI

The iSYS-6003 GUI is a software that communicates with the iSYS-6003 and displays

measurement results. There are a variety of features that can be selected and displayed.

Please refer to the document “iSYS-6003_GUI_manual.pdf” for detailed explanation.

In this document a very brief introduction is given to you, so that you can see first results on

your PC screen.

• Start the GUI

After starting the GUI you see the following window:

Minimize, maximize

or close the GUI

COM Port Config

connects the GUI to

the Sensor. The

command is available

as button or in the

menu Config



• Please select COM Port Config for establishing a connection to the sensor:

Troubleshooting:

1) Connection cannot be established

Solution:

1) Turn sensor off and on again

2) Restart iSYS-6003 GUI

3) Check COM Port

4) Check Switch (USB or RS-485) on the interface board

All available COM ports

are displayed here. A

connection to the iSYS-

6003 sensor can only be

established if the virtual

COM Port for the CP210x

is found.

Press Refresh to update the available COM

ports. (This can help if the CP210x COM port

is not found.)

Select the correct COM

port for the CP210x here

The default baud rate is

115200. Do not change

this value, when you first

establish connection to

the sensor. With the GUI

you can change the Baud

rate later if you need.

The device address is

important when you

communicate with the sensor

over RS-485 or USB. The

address must be set to 100

for USB communication.

Press Connect after everything is selected appropriately. The connection

process may take several seconds. After successful connection the red

light switches to green and the window closes automatically.

Select iSYS-6xxx for your

sensor.



• Display results in the GUI

When connection is established the Main window appears:

The Record/Playback

functionality is

described in the iSYS-

6003_GUI_manual

.pdf document.

The different tabs

provide different

ways to display the

measurement results.

Start / Stop Live View

starts / ends the

transmission and

display of the

measurement results

Freeze… / Run…

freezes the GUI display.

This can be helpful for

signal investigations.

Received sensor I- and

Q- signals are displayed

When parameters have

been changed (e.g.

Baudrate or threshold

parameters) they can

be stored in the sensor

EEPROM as default

values. (Be careful!)

X- and y- axis can be

modified by clicking on

them. (The axis is

displayed bold.) Turning

the mousewheel scales

the axis. A double click

scales automatically.

“Drag and drop”

functionality is also

implemented by

keeping the left mouse

button pressed.



• The Detection Tab

Please press Start Live View and switch to the Detection tab.

This Tab is very important for you, because here you can set parameters that

influence whether a target is being detected as such or not.

The received signal energy (from probably more than one target) is represented

in the frequency domain by calculation of the FFT. Targets with a greater

distance to the sensor cause a signal with a higher frequency in the receiver and

therefore appear further right in the plot.

The blue lines represent the

energy that is scattered

from targets in front of the

iSYS-6003. By evaluating the

energy with an FFT

algorithm, the received

energy is plotted vs. target

distance.

X-axis: The parameter “Bin”

is proportional to target

distance and could be

recalculated in meters.

Y-axis: The parameter

“Amplitude” represents the

amount of energy scattered

by a target at a certain

distance and is therefore an

indicator for target size.

(Don’t forget: You can

adjust the axis as desired)

The threshold determines

how much energy needs to

be scattered to the sensor

(by a target) in order to

declare presence of a valid

target. When a blue line

surpasses the threshold

level, a target is being

detected. (See green

region.)

Parameters to adjust the

threshold level to your

specific application scenario.

(For more information see

the GUI manual.)

Number of current

detections.

Zoom into the region with

the 2 detections. The

orange shaped regions are

detection 1 and 2. As you

see, more than one “Bin”

is clustered as a target.



As you see, there is energy present at all target distances due to noise energy in

the sensor. This is common to all radar sensors! To discriminate against scattered

target energy and noise energy a threshold needs to be set in the GUI. Only

when the energy is enough to surpass the threshold level, a target is detected.

Please adjust the threshold level to make it convenient for your application. You

can use the parameters Sensitivity and Minimum to do that.

As robust detection of targets is a key criteria for radar sensors and adjusting

the threshold is sometimes a cumbersome task, do not hesitate to ask

InnoSenT for support. We have the knowledge and the tools to realize more

sophisticated thresholds for you that are not implemented in the demonstration

kit.



• The Output 1 tab

Please switch to the Output 1 tab:

Feel free to experiment with the settings described here. For more information

please read the GUI manual.

This plot shows the targets

that have been detected as

blue dots. The x-axis gives

you the range to the target,

the y-axis the amount of

scattered energy (Signal

amplitude in dB).

This plot shows the target

detections over time. The x-

axis gives you a time

information and cannot be

scaled. The y-axis displays

the range to the target.

(Only one target is displayed,

because the y-axis was

scaled to 2.6 m and the

second target is at 2.9 m.)

The distance to the target is

shown here. If no special

filtering options in the

“Target Filter Type” sections

are applied, the target

distance to the target with

the highest amplitude is

printed here.

Regions (range and signal amplitude), where target detection

shall be carried out can be defined here. For detailed

information please see the GUI manual.

Here, detected target can be further filtered with the

SingleTargetFilter Option. If there is only one target of

interest, you can for example choose the one with highest

amplitude or minimum range to the sensor.
