ports and LED feedback for remote sources connected to the NetLinx CardFrame,

NI-4000, or NetModule:

NXC-COM2 Pinouts and Wiring Information:

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.

NXC-COM2 Programming Information:

FIG. 1 NXC-COM2 Dual COM Port Control card

NXC-COM2 (FG 2022) Specifications

Operation: Data 1-2: Two RS-232/422/485 control ports, supports

XON/XOFF, CTS/RTS

Status LEDs

(2 per channel):

• Red LEDs show TX (transmit) data activity

• 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

NXC-COM2 Send_Commands

B9MOFF

Disable 9-bit in

232/422/455 mode.

This command works in

conjunction with the

B9MON command.

Syntax:

SEND_COMMAND <DEV>,"'B9MOFF'"

Example:

SEND_COMMAND SOMEDEVICE_1,"'B9MOFF'"

Sets the port settings on SOMEDEVICE to match the port's

configuration settings.

B9MON

Enable 9-bit in

232/422/455 mode.

This command works in

conjunction with the

B9MOFF command.

Syntax:

SEND_COMMAND <DEV>,"'B9MON'"

Example:

SEND_COMMAND SOMEDEVICE_1,"'B9MON'"

Resets the SOMEDEVICE port's communication parameters to

nine data bits and one stop bit.

CHARD

Set the delay time

between all transmitted

characters to the value

specified (in 100 micro-

second increments).

Syntax:

SEND_COMMAND <DEV>,"'CHARD-<Time>'"

time: 0 - 255. Measured in 100 microsecond increments.

Example:

SEND_COMMAND RS232_1,"'CHARD-10'"

Sets a 1-millisecond delay between all transmitted characters.

CHARDM

Set the delay time

between all transmitted

characters to the value

specified

(in 1 millisecond

increments).

Syntax:

SEND_COMMAND <DEV>,"'CHARDM-<Time>'"

time: 0 - 255. Measured in 1 millisecond increments.

Example:

SEND_COMMAND RS232_1,"'CHARDM10'"

Sets a 10-millisecond delay between all transmitted

characters.

CTSPSH

Enable Pushes,

Releases, and status

information to be reported

via channel 255 using the

CTS hardware handshake

input.

If Clear To Send (CTS) is set high, then channel 255 is On.

Syntax:

SEND_COMMAND <DEV>,"'CTSPSH'"

Example:

SEND_COMMAND RS232_1,"'CTSPSH'"

Sets the RS232_1 port to detect changes on the CTS input.

CTSPSHOFF

Disable Pushes,

Releases, and Status

information to be reported

via channel 255.

Syntax:

SEND_COMMAND <DEV>,"'CTPSH OFF'"

Example:

SEND_COMMAND RS232_1,"'CTSPSH OFF'"

Disables the RS232_1 port to detect changes on the CTS

input.

GET BAUD

Get the RS-232/422/485

port’s current

communication parame-

ters.

Device sends the

response out the Master

program port.

Syntax:

SEND_COMMAND <DEV>,"'GET BAUD'"

Example:

SEND_COMMAND RS232_1,"'GET BAUD'"

Device responds with:

485 <ENABLED | DISABLED>

HSOFF

Disable hardware

handshaking (default).

Syntax:

SEND_COMMAND <DEV>,"'HSOFF'"

Example:

SEND_COMMAND RS232_1,"'HSOFF'"

Disables hardware handshaking on the RS232_1 device.

HSON

Enable RTS

(ready-to-send) and CTS

(clear-to-send) hardware

handshaking.

Syntax:

SEND_COMMAND <DEV>,"'HSON'"

Example:

SEND_COMMAND RS232_1,"'HSON'

Enables hardware handshaking on the RS232_1 device.

RXCLR

Clear all characters in the

receive buffer waiting to

be sent to the Master.

Syntax:

SEND_COMMAND <DEV>,"'RXCLR'"

Example:

SEND_COMMAND RS232_1,"'RXCLR'"

Clears all characters in the RS232_1 device's receive buffer.

RXOFF

Disable the transmission

of incoming received

characters to the Master

(default).

Syntax:

SEND_COMMAND <DEV>,"'RXOFF'"

Example:

SEND_COMMAND RS232_1,"'RXOFF'"

Stops the RS232_1 device from transmitting received

characters to the Master.
