AMX NI-3000, NI-4000, NI-2000 instruction manual RS-232/422/485 SendString Escape Sequences

Programming

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

TXCLR Syntax:

Stops and clears all	SEND_COMMAND <DEV>,'TXCLR'
characters waiting in the	Example:
transmit buffer.
	SEND_COMMAND RS232_1,'TXCLR'
	Clears and stops all characters waiting in the RS232_1 device's transmit buffer.
XOFF	Syntax:
Disables software	SEND_COMMAND <DEV>,'XOFF'
handshaking (default).	Example:
	SEND_COMMAND RS232_1,'XOFF'
	Disables software handshaking on the RS232_1 device.
XON	Syntax:
Enables software	SEND_COMMAND <DEV>,'XON'
handshaking.	Example:
	SEND_COMMAND RS232_1,'XON'
	Enables software handshaking on the RS232_1 device.

RS-232/422/485 Send_String Escape Sequences

RS-232/422/485 Send_String Escape Sequences

27,17, Syntax:

Sends device-specific break	SEND_STRING <DEV>,"27,17,<Time>"
characters for a specified	Variable:
duration.
	Time = 1-255 in 100 microsecond increments
	Example:

	SEND_STRING RS232_1,"27,17,10"
	Sends a break character of 1 millisecond to the RS232_1 device.
27,18,1	You can use this escape sequence with the B9MON command.
Sets the ninth data bit to 1 on	Syntax:
all character transmissions.	SEND_STRING <DEV>,"27,18,1"
	Example:
	SEND_STRING RS232_1,"27,18,1"
	Sets the RS232_1 device's ninth data bit to 1 on all character transmissions.
27,18,0	You can use this escape sequence with the B9MON command.
Sets the ninth data bit to 0 on	Syntax:
all character transmissions.	SEND_STRING <DEV>,"27,18,0"
	Example:
	SEND_STRING RS232_1,"27,18,0"
	Sets the RS232_1 devices ninth data bit to 0 on all character transmissions.
27,19,	Syntax:
Inserts time delays before	SEND_STRING <DEV>,"27,19,<Time>"
transmitting the next	Variable:
character.
	Time = 1-255 in 1 millisecond increments
	Example:
	SEND_STRING RS232_1,"27,19,10"
	Inserts a 10 millisecond delay before transmitting characters to the RS232_1
	device.
