RS-232/422/485 SEND_COMMANDs (Cont.)
Command Description
SET BAUD Set the RS-232/422/485 port's communication parameters.
NOTE: On NX-series controllers, ports 1&5 support RS-232, RS-422, or RS485. The three modes are mutually
exclusive. Setting any of the three modes disables the other two.
NOTE: The RS-232 ports on Massio ControlPads are RS-232 only, so sending the SEND_COMMAND to Enable 422 or
485 mode on a Massio ControlPad via Telnet will have no effect on the ControlPad, and the ControlPad will not
return an error message.
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,<stop> [422 Enable | 485 Enable]'"
NOTE: Serial modes are mutually exclusive. RS-232 is specified by omitting 422 Enable and 485 Enable. Enabling
422 effectively disables 232 and 485. Enabling 485 effectively disables 232 and 422.
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 = 8 data bits.
stop = 1 and 2 stop bits.
422 Enable = Enables 422 (Disables 232/485)
485 Enable = Enables 485 (Disables 232/422)
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.
SET FAULT
DETECT OFF
Disables fault detection on the port. Fault detection is turned on by default.
Syntax:
SEND_COMMAND <DEV>, "'SET FAULT DETECT OFF'"
Example:
SEND_COMMAND RS232_1,"'SET FAULT DETECT OFF'"
SET FAULT
DETECT ON
Enables fault detection on the port. Fault detection is turned on by default.
Syntax:
SEND_COMMAND <DEV>, "’SET FAULT DETECT ON’"
Example:
SEND_COMMAND RS232_1,"’SET FAULT DETECT ON’"
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.
NOTE: On NX-series controllers, ports 1&5 support RS-232, RS-422, or RS485. The three modes are mutually
exclusive. Setting any of the three modes disables the other two.
NOTE: The RS-232 ports on Massio ControlPads are RS-232 only, so sending the SEND_COMMAND to Enable 422 or
485 mode on a Massio ControlPad via Telnet will have no effect on the ControlPad, and the ControlPad will not
return an error message.
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,<stop> [422 Enable | 485 Enable]'"
NOTE: Serial modes are mutually exclusive. RS-232 is specified by omitting 422 Enable and 485 Enable. Enabling
422 effectively disables 232 and 485. Enabling 485 effectively disables 232 and 422.
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.
422 Enable = Enables 422 (Disables 232/485)
485 Enable = Enables 485 (Disables 232/422)
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.
