Chapter 2 - Interfacing to Repeater

CAT-1000 Controller Interface

Connect the WX-200 to the CAT-1000B and the repeater as shown in Figure 2-1A. PTT and transmit

audio from the CAT-1000B are connected to the repeater's transmitter through the normally closed

contacts of the double pole double throw relay located in the WX-200. Set the power switch to on,

the WX-200 will announce the firmware version. When a weather alert is received, the relay will

switch the weather alert audio to the TX audio input and provide a PTT signal to key the transmitter.
