Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Serial SEND_COMMANDs (Transmitters and Receivers), continued
GET BAUD
Get the RS-232 (serial)
port’s current communication
parameters.
The port sends the parameters to the device that requested the information.
Syntax:
SEND_COMMAND <DEV>,"'GET BAUD'"
Example:
SEND_COMMAND dvRXRS232,"'GET BAUD'"
The port responds with:
Port <port #>,<baud>,<parity>,<data>,<stop>
RXCLR
Clear all characters in the
receive buffer waiting to be
sent to the Master.
Syntax:
SEND_COMMAND <DEV>,"'RXCLR'"
Example:
SEND_COMMAND dvRXRS232,"'RXCLR'"
Clears all characters in the receive buffer waiting to be sent to the Master.
RXOFF
Disable the transmission of
incoming received
characters to the Master
(default).
Syntax:
SEND_COMMAND <DEV>,"'RXOFF'"
Example:
SEND_COMMAND dvRXRS232,"'RXOFF'"
Disables the transmission of incoming received characters to the Master.
RXON
Start transmitting received
characters to the Master.
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 dvRXRS232,"'RXON'"
Sets the RX RS-232 port to transmit received characters to the Master.
TXCLR
Stop and clear all characters
waiting in the transmit out
buffer and stops
transmission.
Syntax:
SEND_COMMAND <DEV>,"'TXCLR'"
Example:
SEND_COMMAND dvRXRS232,"'TXCLR'"
Stops and clears all characters waiting in the RX serial port’s transmit buffer.
SET BAUD
(shown in examples)
Or
TSET BAUD
Use either of these
commands to set the serial
communication parameters.
Note:
The
DXLink
Transmitters and Receiver
only support RS-232 serial
communication.
Note:
This value is not saved in non-volatile memory and is reset to default
(9600, N, 8, 1) at power-up.
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,
<stop>'"
Variables:
• baud = 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 or 2 stop bits
Note:
The only valid 9 bit combination is (baud),N,9,1.
Example:
SEND_COMMAND DEVICE_1,"'SET BAUD 115200,N,8,1'"
Sets the DEVICE_1 port’s communication parameters to 115,200 baud, no
parity, 8 data bits, and 1 stop bit.
