Communication

If the communication system is radio, look for:

• a radio j-box near the computer.
• a server radio outside the building and a second radio at the display.

Cable

Connections

The serial cable connects the computer to the radio j-box.

All the wires are connected at the radio j-box and at the “server” radio; the

wires make good electrical contact with the metal, no interference.

The color sequence of the wires should be the same to both the radio j-box

and the server (e.g. black, white, red and black, white, red).

The cable is connected from the radio client to the top jack on back of

display.

Diagnostic

LEDs

The green LED will be on when the radio j-box has power.

The amber LED is on when the computer is connected to the radio j-box.

The red and amber transmit and receive LEDs will flash when sending and

receiving signal from the display; otherwise they are off.

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.
