RS-232/422/485 Send_Commands
Command
Description
B9MOFF
Set the port's communication
parameters for stop and data
bits according to the software
settings on the RS-232 port
(default).
Disables 9-bit in 232/422/455 mode. By default, this returns the communication
settings on the serial port to the last programmed parameters. This command
works in conjunction with the 'B9MON' command.
Syntax:
SEND_COMMAND <DEV>,"'B9MOFF'"
Example:
SEND_COMMAND RS232_1,"'B9MOFF'"
Sets the RS-232 port settings to match the port's configuration settings.
B9MON
Override and set the current
communication settings and
parameters on the RS-232
serial port to 9 data bits with
one stop bit.
Enables 9-bit in 232/422/455 mode. This command works in conjunction with
the 'B9MOFF' command.
Syntax:
SEND_COMMAND <DEV>,"'B9MON'"
Example:
SEND_COMMAND RS232_1,"'B9MON'"
Resets the RS-232 port's communication parameters to nine data bits, one
stop bit, and locks-in the baud rate.
CHARD
Set the delay time between
all transmitted characters to
the value specified (in 100
Microsecond increments).
Syntax:
SEND_COMMAND <DEV>,"'CHARD-<time>'"
Variable:
time = 0 - 255. Measured in 100 microsecond increments.
Example:
SEND_COMMAND RS232_1,"'CHARD-10'"
Sets a 1-millisecond delay between all transmitted characters.
CHARDM
Set the delay time between
all transmitted characters to
the value specified
(in 1 Millisecond increments).
Syntax:
SEND_COMMAND <DEV>,"'CHARDM-<time>'"
Variable:
time = 0 - 255. Measured in 1 millisecond increments.
Example:
SEND_COMMAND RS232_1,"'CHARDM-10'"
Sets a 10-millisecond delay between all transmitted characters.
CTSPSH
Enable Pushes, Releases,
and Status information to be
reported via channel 255
using the CTS hardware
handshake input.
This command turns On (enables) channel tracking of the handshaking pins. If
Clear To Send (CTS) is set high, then channel 255 is On.
Syntax:
SEND_COMMAND <DEV>,"'CTSPSH'"
Example:
SEND_COMMAND RS232_1,"'CTSPSH'"
Sets the RS232_1 port to detect changes on the CTS input.
CTSPSH OFF
Disable Pushes, Releases,
and Status information to be
reported via channel 255.
This command disables tracking. Turns CTSPSH Off.
Syntax:
SEND_COMMAND <DEV>,"'CTSPSH OFF'"
Example:
SEND_COMMAND RS232_1,"'CTSPSH OFF'"
Turns off CTSPSH for the specified device.
