NXC-COM2 (FG 2022) Specifications
Power Requirements: 140 mA @ 12 VDC
Operation: Data 1-2: Two RS-232/422/485 control ports, supports
XON/XOFF, CTS/RTS
Status LEDs • Red LEDs show TX (transmit) data activity
(2 per channel):
• Yellow LEDs show RX (receive) data activity
- LED 1: CH1 TX (red)
- LED 2: CH1 RX (yellow)
- LED 3: CH2 TX (red)
- LED 4: CH2 RX (yellow)
• Green ICSP status LED (located on the board):
- On = card is not in communication with the Master.
- Blinks (1-second intervals) during normal operation.
Connections/wiring: Two 10-pin 3.5 mm captive-screw terminals
DEVICE_ID: $0107

NXC-COM2 Channel Assignment:
Channel 255 is the CTS (Clear To Send) push channel. It reflects the state of the CTS
input if a 'CTSPSH' command was sent to the device.
