4.7 Ethernet Bridge Radio Communication
If the communication system is a wireless Ethernet bridge radio, look for:
• a DC injector connected to the network, server radio, and a 120 VAC outlet.
• a server (transmitter) radio mounted on the building and a client (receiver) radio at
the display.
Note: This system is referred to as Ethernet "bridge" communication because it requires a pair
of matched radios to create a signal connection or bridge.
Connections
• Computer to network − RJ45 cable from computer port into network server in building.
• Network switch to DC injector - RJ45 cable from network to "DATA IN" jack.
• Wall power adapter - DC injector power adapter to 120 VAC outlet.
• DC injector to server radio - RJ45 cable from "P+DATA OUT" to server radio.
• Server radio to client radio - clear line of sight for signal transmission.
• Client radio to display − quick-connect cable to the middle jack on display side.

Cable
Connections
• A cable connects the computer to the network switch/router.
• A cable runs from the network switch to the DC injector.
• The DC injector is plugged into a 120 VAC outlet.
• A cable runs from DC injector to server radio.
• Maximum distance from switch to server radio is 300 feet (100M)
• The quick-connect cable runs from client radio to top jack on side of display.
Diagnostic
LEDs
• The DC injector's green LED should be on, indicating power.
• Both radios have internal LEDs. Refer to the Wireless Ethernet manual for
their specifications.
Display
Power
• The display is either running a message or showing a single pixel flashing in
the bottom right corner of the display when power is on.
Software
• The software and the display are set for the same network address.
• Refer to the software manual for other possible conditions.
