UltraWave Product Guide
Power supply connection
When a central low voltage power supply is being used for primary power, it should be powered
from an uninterruptible power source.
•
To power the system from a central source, run the power distribution cable around the
perimeter and tap off to each UltraWave unit.
•
At each UltraWave unit, splice the power cable to a lighter gauge pigtail that is approximately
30 cm (12 in.) long. Connect the negative lead to T3-1 (-) and connect the positive lead to
T3-2 (+) (see
Local power supply
To use a local DC power supply, the power supply must be outdoor rated and installed in its own
weatherproof enclosure. The local supply can be mounted on the same post as the UltraWave unit
to keep the wire runs to a minimum. Connect the negative lead to T3-1 (-) and connect the positive
lead to T3-2 (+) (see
Power over Ethernet
For power over Ethernet, a class 3 PoE switch is required. In this configuration, minimum Category
5 cable is also required and the maximum distance between the UltraWave transmitter/receiver
and the PoE switch is 100 m (328 ft.). Each unit receiving PoE requires an earth ground
connection. To use PoE, connect the PoE switch to the Ethernet port on the NIC (T1) and then
connect the NIC’s power output (T2) to the power input on the transmitter/receiver unit (T3).

Installing the Network interface card (NIC)
1. Remove the lower cover from the receiver enclosure.
2. Disconnect the power at T3.
3. Remove and retain the hardware from the two standoffs on the receiver circuit card.
4. Insert the 20 pin expansion header on the solder side of the NIC into T1 (the 20 pin socket) on
the receiver. Ensure that all pins are seated correctly, and the two mounting holes on the NIC
align with the two standoffs on the receiver.
5. Using the retained hardware, secure the NIC to the standoffs.
6. Connect the NIC ground strap to the receiver PCB ground connection.
7. Make the network wiring connections (see
Silver Network connections on page 26
).
8. Reconnect the power and replace the enclosure cover.
WARNING!
DO NOT bring AC mains power into the UltraWave enclosure. If a
local power supply is being used, it must be installed in its own
weatherproof enclosure. Consult the local electrical code for
information about the connection of AC mains to your power supply.
CAUTION
The PoE NIC is intended to supply power only to the transmitter/
receiver on which it is mounted. It is not recommended to use the
PoE NIC to power an auxiliary device.
Note
A network interface card must be installed on the UltraWave receiver
to enable network communications.
