FRONT PANEL COMPONENTS

• Master/Hub Card slot: Accepts an NXC-ME260 or Hub Card
• RS-232/422/485 TX/RX LEDs: Six sets of red and yellow LEDs light to indicate ports 1-6 are transmitting or receiving RS-232, 422, or 485 data:
  - TX LEDs (red) blink when transmitting data
  - RX LEDs (yellow) blink when receiving data
• Relay LEDs: Twelve red LEDs light to indicate relay channels 1-12 are active (closed)
• IR/Serial LEDs: Eight red LEDs light to indicate IR/Serial channels 1-8 are transmitting control data
• I/O LEDs: Eight yellow LEDs light when I/O channels 1-8 are active

REAR PANEL CONNECTORS

• ID Pushbutton: Sets the D:P:S assignment for the NXI
• ICSP LED: Green LED Blinks in unison with the Master card’s NetLinx LED indicating the ICSP bus is synchronized. This LED flashes rapidly when the NXI is in ID Mode (see Using the ID Button for details)
• RS-232/422/485 Ports (#1-6): Six RS-232/422/485 control ports with XON/ XOFF (transmit on/transmit off), and CTS/RTS (clear to send/ready to send), 300-230,400 baud:
  - Channel range = 1-255
  - Channels 1-254 provide feedback only.
  - Channel 255 (CTS Push channel) reflects the state of the CTS
  - Input if a ‘CTSPSH’ command was sent to the port.
• Relays Port (# 7): Twelve-channel relay port. Channel range = 1-12
  - You can connect up to 12 independent external relay devices to the Relay connectors on the NXI (port 7)
  - Connectors labeled A are for common and B are for Output
  - Each relay is isolated and normally open
• IR/Serial Ports (# 8-15): Eight IR/Serial control ports that support high-frequency carriers up to 1.14 MHz:
  - Channel range = 1-32,000
  - Channels 1-253 (output): IR commands
  - Channel 254 (feedback): PowerFail (used with ‘PON’ and ‘POF’ commands)
  - Channel 255 (feedback): Power status (when IOLink is set).
• I/O Port (# 16): 8-channel I/O port for contact closure, 0-5 VDC voltage sensing, or interactive power sensing for IR ports. Channel range = 1-8
