3. INSTALLATION
All necessary cables are provided with each EX-4 to connect to four base units as shown below. Each base
unit requires a RS232 connection to it's keypad connector and also coax from monitor output to EX-4.
Base unit number 1 supplies power for the EX-4, to maintain a low resistance path do not extend this RS232
cable. The other RS232 cables can be extended up to 50M. Should a greater distance be require, then a
TxLD can be used to allow operation 500M between EX-4 and base unit.
Fig 1. EX-4 connections
Each base unit has a corresponding LED which flashes on key presses to indicate the selected base unit. The
flash rate is fixed at the keypad baud rate causing the LEDs to not reach full brightness. Simply shield the
LEDs from ambient light if required.
The Power LED is illuminated indicating power is present.
