RS-232/422/485 Send_Commands (Cont.)

Command	Description
RXOFF	Syntax:
Disable the transmission of	SEND_COMMAND <DEV>,"'RXOFF'"
incoming received	Example:
characters to the Master	SEND_COMMAND RS232_1,"'RXOFF'"
(default).	Stops the RS232_1 device from transmitting received characters to the Master.
RXON	Enables sending incoming received characters to the Master. This command is
Start transmitting received	automatically sent by the Master when a 'CREATE_BUFFER' program
characters to the Master	instruction is executed.
(default).	Syntax:
	SEND_COMMAND <DEV>,"'RXON'"
	Example:
	SEND_COMMAND RS232_1,"'RXON'"
	Sets the RS232_1 device to transmit received characters to the Master.
SET BAUD	Syntax:
Set the RS-232/422/485	SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,<stop> [485
port's communication	<Enable Disable>]'"
parameters.	Variables:
	baud = baud rate is: 115200.
	parity = N (none), O (odd), E (even), M (mark), S (space).
	data = 7 or 8 data bits.
	stop = 1 and 2 stop bits.
	485 Disable = Disables RS-485 mode and enables RS-422.
	485 Enable = Enables RS-485 mode and disables RS-422.
	Note: The only valid 9 bit combination is (baud),N,9,1.
	Example:
	SEND_COMMAND RS232_1,"'SET BAUD 115200,N,8,1 485 ENABLE'"
	Sets the RS232_1 port's communication parameters to 115,200 baud, no
	parity, 8 data bits, 1 stop bit, and enables RS-485 mode.
TSET BAUD	TSET BAUD works the same as SET BAUD, except that the changes are not
Temporarily set the RS-232/	permanent, and the previous values will be restored if the power is cycled on
422/485 port's	the device.
communication parameters	Syntax:
for a device.	SEND_COMMAND <DEV>,"'TSET BAUD <baud>,<parity>,<data>,<stop> [485
	<Enable Disable>]'"
	Variables:
	baud = baud rate is: 115200.
	parity = N (none), O (odd), E (even), M (mark), S (space).
	data = 7, 8, or 9 data bits.
	stop = 1 or 2 stop bits.
	485 Disable = Disables RS-485 mode and enables RS-422.
	485 Enable = Enables RS-485 mode and disables RS-422.
	Note: The only valid 9 bit combination is (baud),N,9,1.
	Example:
	SEND_COMMAND RS232_1,"'TSET BAUD 115200,N,8,1 485 ENABLE'"
	Sets the RS232_1 port's communication parameters to 115,200 baud, no
	parity, 8 data bits, 1 stop bit, and enables RS-485 mode.
TXCLR	Syntax:
Stop and clear all characters	SEND_COMMAND <DEV>,"'TXCLR'"
waiting in the transmit out	Example:
buffer and stops transmis-	SEND_COMMAND RS232_1,"'TXCLR'"
sion.	Clears and stops all characters waiting in the RS232_1 device's transmit buffer.
