3.4.4 Inputs and Outputs

The Input/Output control combines several functions:

1. The User Defined options let you test the Digital Signal Processor’s input

and output buses. If everything is working correctly, the Fault indicator will

remain unlit.

2. The Radiate command lets you turn on the transmitter.

3. The Fault, Filament ready, and Airflow Good indicators let you monitor

system status. These indicators do not change dynamically after you open

the Input/Output dialog box. You must press the Refresh Status button to

update the status indicators.

4. The Reset Modulator sends a reset pulse to the modulator circuitry. This

normally clears any system fault interlock logic. (If the fault condition persists,

the fault interlock logic may cause a new fault again.)
