Command Description
RXOFF
Disable the transmission of
incoming received
characters to the Master
(default).
Syntax:
SEND_COMMAND <DEV>,"'RXOFF'"
Example:
SEND_COMMAND RS232_1,"'RXOFF'"
Stops the RS232_1 device from transmitting received characters to the Master.
RXON
Start transmitting received
characters to the
Master (default).
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:
SEND_COMMAND <DEV>,"'RXON'"
Example:
SEND_COMMAND RS232_1,"'RXON'"
Sets the RS232_1 device to transmit received characters to the Master.
SET BAUD
Set the RS-232/422/485
port's communication
parameters.
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD
<baud>,<parity>,<data>,<stop> [485 <Enable |
Disable>]'"
Variables:
baud = baud rates are: 115200, 76800, 57600, 38400, 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 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.
