both Ground Control and GCX with the GCX power switch. Then turn power back on. 
After the Ground Control finishes its startup message the Active LED on the GCX will 
blink and then stay on. This indicates that the Ground Control and GCX are successfully 
communicating. 
Controlling GCX Loops 
Now that you have setup your Ground Control to access the GCX, you can easily control 
each of the eight loops. 
1. Press [SELECT
∨] until the Ground Control display reads "GCX-1". 
2.  Pressing [1] through [8] will control GCX loops. The Status LED's on the GCX front 
panel, and the LED next to each button on the Ground Control will show the current 
status of each loop.
