Cervis, Inc. Safety Precautions

✓ Read and follow all instructions.

✓ Failure to abide by Safety Precautions may cause equipment failure, loss of authority to operate the equipment, and personal injury.

✓ Use and maintain proper wiring. Follow equipment manufacturer instructions. Improper, loose, and frayed wiring can cause system failure, equipment damage, and intermittent operation.

✓ Changes or modifications made to equipment not expressly approved by the manufacturer will void the warranty.

✓ Equipment owner/operators must abide by all applicable Federal, State, and Local laws concerning equipment installation and operation. Failure to comply could result in penalties and could void user authority to operate the equipment.

✓ Make sure that the machinery and surrounding area is clear before operating. Do not activate the system until certain that it is safe to do so.

✓ Use a damp cloth to keep units clean. Remove mud, concrete, dirt, etc. after use to prevent obstructing or clogging the buttons, wiring, and switches.

✓ Do not allow liquid to enter enclosures. Do not use high-pressure equipment to clean the unit.

✓ Operate and store units only within the specified operation and storage temperatures defined in this document’s specifications.

✓ Keep high-energy radio frequency (RF) devices away from the unit. Activating high-power communication radios, for instance, in close proximity to the devices could cause interference and “false” circuit activation.

The field data units (FDUs) directly communicate with the ZDU via Channel-Hopping Direct Sequence Spread Spectrum (CH DSSS) 900 MHz radio frequency (RF) to convey analog input data gathered from a sensor connected to the unit.

Three AAA cell alkaline or rechargeable nickel metal hydride (NiMH) batteries power each module for approximately 12 hours of continuous operation before needing to be replaced or recharged.

3.1 Battery Installation or Charge Three AAA cell batteries power all FDUs. When installing batteries, be sure to observe proper polarity to avoid damaging the unit.

To replace or install batteries:

1. Loosen the four small Phillips screws from the top cover (see below), and carefully lift it off the unit. The screws remain attached to the cover.

✓Note: A power supply cable connects the FDU’s battery pack

(attached to the top cover) to its printed circuit board (PCB). While it is not necessary to disconnect this cable when changing the batteries, it is important to be gentle when separating the top cover from the rest of the unit because it is possible to damage the cable.

U126.A.0 10

2. If installing batteries in an empty battery compartment, install three fresh AAA cell batteries. Be sure to position the batteries as shown below.

3. If replacing expired batteries, remove the old batteries, and install three fresh AAA cell batteries. Be sure to position the batteries as shown below.

4. Replace the compartment cover, and tighten the four Phillips screws.



✓Note: Do not over-tighten these screws, but make sure they

are tight enough to properly seal the gasket.

3.1.1 Optional Recharger Kit

Using rechargeable NiMH batteries can save you money on battery supplies, usage, and waste. However, to recharge those batteries, you must open the unit and remove the batteries to charge them, which can be time-consuming. (See Section 3.1.)

Consequently, Cervis, Inc. has assembled an optional NiMH battery recharger kit that allows you to keep rechargeable batteries inside the field unit housing while they’re charging. This saves you time and effort when keeping your units fully charged and field-ready.

The kit consists of the following components:

• SkyRC® iMAX® B6 LiPro Balance Charger Unit (see Figure 6)

• DC Supply Plug (wall socket)

• Car Cigarette Lighter DC Supply Adapter (for on-the-road charging)

• 22 AWG Adapter Charge Cable (connects to one field data unit; multiple unit connectors may also be ordered, see Figure 6)

To charge batteries:

1. Connect the battery charge cable to the bottom socket on the field unit you want to recharge.

2. Using the proper DC supply cable, connect the battery charger unit to a nearby wall socket—or your vehicle’s cigarette lighter socket—and press “Start/Enter.”

U126.A.0 12

The unit begins charging the batteries inside the unit. The charger alerts you when the batteries are fully charged.

Figure 9. FDU-9X-VIN LED (Unit Inactive)

✓Note: The LED is not daytime-viewable when transmitting

data in outside environments. To make sure your unit is transmitting properly, cast a shadow over the LED with your hand, a clipboard, or any other appropriate object.

4.0 Building a System

Follow these steps to establish the communications network between the FDU node system and ZDU:

1. Ensure that all nodes are powered down. If they aren’t, press and hold the power button down for approximately two seconds.

The indicator LED briefly lights solid before going out.

2. Attach the ZDU to your device’s USB port. (The ZDU is attached to a Microsoft Surface Pro tablet in the image below.)



The ZDU immediately enters standby mode. The bottom LED begins blinking twice per second.

✓Note: Because the devices operate at a 115.2 Kbps baud

rate, ensure that the program you are running is set for that baud rate before collecting data.

3. Press and hold the ON/OFF button on the first FDU node for approximately one second.

U126.A.0 20

Release the button when the LED lights solid. The LED begins flashing when transceiving.

Both LEDs on the ZDU also begin flashing.

Attach the field node to the sensor via the cable, and connect the sensor to the data source.



The unit immediately begins transmitting data to the ZDU.

✓Note: If the sensor does transmit data to the ZDU, it might

not be getting enough power from the FDU. In that case, shut the system down, remove the FDU cover, and flip DIP switch 1 up to the ON position to boost the power level from +5 to +12 VDC. Then, reassemble the FDU, and restart the system. If your system still doesn’t operate as expected, contact Cervis, Inc.

4. Press and hold the ON/OFF button on the second unit for approximately one second.

U126.A.0 22

Release the button when the LED lights solid. The LED begins blinking when transceiving.

Attach the node to the sensor via the cable, and connect the sensor to the data source.



The unit immediately begins transmitting data to the ZDU.

Sequentially repeat Step 5 for each subsequent FDU used in the network.

✓Note: The communications network remains operational for

as long as all field units are operating and communicating with the ZDU. Shutting off one field unit may collapse one or more nodes in the network.
