Each Display Unit includes a network communication Eprom and address switch module. This module plugs into the keyboard connector socket adjacent to the power connector and enables you to set an address for the associated unit. When the Display Unit is powered up, it reads the network address from the switch module.

Addresses are set by setting the required values on the two rotary switches of the address module. An address can be any value between 01 and 99 and each display in the network should have a different address number.
The maximum number of displays that can be connected to a single PC Serial Port will depend on the type of display and baud rate used to transfer informa- tion.
