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 a command and not the literal characters. In these
examples: <DEV> = device.
IR / Serial Ports Channels
NOTE: The NI series of NetLinx Masters support Serial control via the IR/RX port when using f irmware version 300 or greater.
RS-232/422/485 SEND_STRING Escape Sequences
Command Description
27,17,<time> Send a break character for a specified duration to a specific device.
Syntax:
SEND_STRING <DEV>,"27,17,<time>"
Variable:
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 Clear the ninth data bit by setting it to 0 on all character transmissions. Used in conjunction with the 'B9MON' command.
Syntax:
SEND_STRING <DEV>,"27,18,0"
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 Set the ninth data bit to 1 for all subsequent characters to be transmitted. Used in conjunction with the 'B9MON'
command.
Syntax:
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.
27,19,<time> Insert a time delay before transmitting the next character.
Syntax:
SEND_STRING <DEV>,"27,19,<time>"
Variable:
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 Set the RTS hardware handshake's output to high (> 3V).
Syntax:
SEND_STRING <DEV>,"27,20,0"
Example:
SEND_STRING RS232_1,"27,20,0"
Sets the RTS hardware handshake's output to high on the RS232_1 device.
27,20,1 Set the RTS hardware handshake's output to low/inactive (< 3V).
Syntax:
SEND_STRING <DEV>,"27,20,1"
Example:
SEND_STRING RS232_1,"27,20,1"
Sets the RTS hardware handshake's output to low on the RS232_1 device.
