AMX NI-3101-SIG manual RS-232/422/485 SendString Escape Sequences, Xon

Programming

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

Command	Description
XON	Syntax:
Enable 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

This device also has some special SEND_STRING escape sequences:

If any of the 3 character combinations below are found anywhere within a SEND_STRING program instruction, they will be treated as commands and not the literal characters.

In these examples: <DEV> = device.

RS-232/422/485 Send_String Escape Sequences

Command	Description
27,17,<time>	Syntax:
Send a break character for a	SEND_STRING <DEV>,"27,17,<time>"
specified duration to a	Variable:
specific device.
	time = 1 - 255. Measured in 100 microsecond increments.
	Example:
	SEND_STRING RS232_1,"27,17,10"
	Sends a break character of 1 millisecond to the RS232_1 device.
27,18,0	Used in conjunction with the 'B9MON' command.
Clear the ninth data bit by	Syntax:
setting it to 0 on all character	SEND_STRING <DEV>,"27,18,0"
transmissions.
	Example:
	SEND_STRING RS232_1,"27,18,0"
	Sets the RS232_1 device's ninth data bit to 0 on all character transmissions.
27,18,1	Used in conjunction with the 'B9MON' command.
Set the ninth data bit to 1 for	Syntax:
all subsequent characters to	SEND_STRING <DEV>,"27,18,1"
be transmitted.
	Example:
	SEND_STRING RS232_1,"27,18,1"
	Sets the RS232_1 device's ninth data bit to 1 on all character transmissions.
27,19,<time>	Syntax:
Insert a time delay before	SEND_STRING <DEV>,"27,19,<time>"
transmitting the next	Variable:
character.
	time = 1 - 255. Measured 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.
27,20,0	Syntax:
Set the RTS hardware	SEND_STRING <DEV>,"27,20,0"
handshake's output to high	Example:
(> 3V).
	SEND_STRING RS232_1,"27,20,0"
	Sets the RTS hardware handshake's output to high on the RS232_1 device.
