RS-232/422/485 SEND_COMMANDs (Cont.)
Command
Description
TSET BAUD
Temporarily set the RS-232/422/485 port's communication parameters for a device. TSET BAUD works the same as SET
BAUD, except that the changes are not permanent, and the previous values will be restored if the power is cycled on the
device.
Syntax:
SEND_COMMAND <DEV>,"'TSET BAUD <baud>,<parity>,<data>,<stop> [485 <Enable | Disable>]'"
Variables:
baud = baud rates are: 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200, 600, 300.
parity = N (none), O (odd), E (even), M (mark), S (space).
data = 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
Stop and clear all characters waiting in the transmit out buffer and stops transmission.
Syntax:
SEND_COMMAND <DEV>,"'TXCLR'"
Example:
SEND_COMMAND RS232_1,"'TXCLR'"
Clears and stops all characters waiting in the RS232_1 device's transmit buffer.
XOFF
Disable software handshaking (default).
Syntax:
SEND_COMMAND <DEV>,"'XOFF'"
Example:
SEND_COMMAND RS232_1,"'XOFF'"
Disables software handshaking on the RS232_1 device.
XON
Enable software handshaking.
Syntax:
SEND_COMMAND <DEV>,"'XON'"
Example:
SEND_COMMAND RS232_1,"'XON'"
Enables software handshaking on the RS232_1 device.
