Command Description EXB Modules
RXCLR Clear all characters in the receive buffer waiting to be sent to the
Master.
Syntax:
RXCLR
Example:
SEND_COMMAND RS232_1,"'RXCLR'"
Clears all characters in the receive buffer waiting to be sent to the
Master.
• EXB-COM2
• EXB-MP1
RXOFF Disable the transmission of incoming received characters to the
Master (default).
Syntax:
RXOFF
Example:
SEND_COMMAND RS232_1,"'RXOFF'"
Disable the transmission of incoming received characters to the
Master (default).
• EXB-COM2
• EXB-MP1
RXON Start transmitting received characters to the Master.
Enables sending incoming received characters to the Master.
This command is automatically sent by the Master when a
'CREATE_BUFFER' program instruction is executed.
Syntax:
RXON
Example:
SEND_COMMAND RS232_1,"'RXON'"
Start the RS232_1 device’s transfer of received characters to the
Master.
• EXB-COM2
• EXB-MP1
SET BAUD Set the COM port's communication parameters.
Note: This value is not saved in Non-Volatile memory, and is reset to
default (9600,8,N,1) at power-up.
Syntax:
SET BAUD <baud>,<parity>,<data>,<stop> [485
<Enable|Disable>]
Variables:
• Baud: 19200, 9600, 4800, 2400, 1200, 600, 300, 150.
• Parity: N (none), O (odd), E (even), M (mark), S (space)
• Data: 7 or 8 data bits
• Stop: 1 or 2 stop bits
• 485 Disable (EXB-COM2 Port 1 only): Disables RS-485 mode and
enables RS-232/422
• 485 Enable (EXB-COM2 Port 1 only): Enables RS-485 mode and
disables RS-234/422
Note: The only valid 9 bit combination is (baud),N,9,1.
Example:
SEND_COMMAND DEVICE_1,"'SET BAUD 19200,N,8,1, 485
ENABLE'"
Sets the DEVICE_1 port's communication parameters to 19,200
baud, no parity, 8 data bits, 1 stop bit, and enables RS-485 mode.
Note: The maximum baud rate for ports using DATA mode is 19200.
Also, DATA mode works best when using a short cable length (< 10
feet).
• EXB-COM2
• EXB-IRS4
• EXB-MP1
