Control RS-232: DB9 female, RS-232 data link to control system or PC

iC-Net RS-232: DB9 female, RS-232 data link to send iCW-Net over fiber or codec

I/O 1 & 2: 4-pin captive screw terminal for Input/Outputs 1 and 2

2 switch closures or inputs, max 50 mA, 24 VDC, switch to GND

1 – +12 VDC

2 – Output 2

3 – Output 1

4 – GND

I/O Applications: DC power – close pins 1 & 3 to provide DC on/off

Dry closure 2 – close pins 3 & 4 for dry contact to external power relay,

AMX PC1 or similar

Sense closure (3 & 4) on Input 1 – trigger control system to power off for all

rooms
