RS-232/422/485 SEND_COMMANDs (Cont.)
Command Description
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.
GET BAUD Get the RS-232/422/485 port’s current communication parameters. The port sends the parameters to the
device that requested the information.
The port responds with:
<port #>,<baud>,<parity>,<data>,<stop> 485 <ENABLED | DISABLED>
Syntax:
SEND_COMMAND <DEV>,"'GET BAUD'"
Example:
SEND_COMMAND RS232_1,"'GET BAUD'"
System response example:
Device 1,38400,N,8,1 485 DISABLED
HSOFF Disable hardware handshaking (default).
Syntax:
SEND_COMMAND <DEV>,"'HSOFF'"
Example:
SEND_COMMAND RS232_1,"'HSOFF'"
Disables hardware handshaking on the RS232_1 device.
