Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
SEND_STRING Escape Sequences
The DXLink Modules support several special SEND_STRING escape sequences. If any of the character combinations
listed below are found anywhere within a SEND_STRING program instruction, they will be treated as a command and
not the literal characters.
Use the ESCSEQON and ESCSEQOFF NetLinx SEND_COMMANDS to control whether these are active or not.
The ESCSEQON command must precede the Escape Sequences, otherwise the strings will be processed normally.
These commands are sent to Port 1.
DXLink System SEND_COMMANDs (Transmitters and Receivers), continued
Command Description
SET TELNET PORT 0
Sets the Telnet port to “0” (disabled
state).
Syntax:
SEND_COMMAND <DEV>,"'SET TELNET PORT 0'"
Example:
SEND_COMMAND dvRX,"'SET TELNET PORT 0'"
Note: A reboot is required after sending the SET TELNET PORT 0 command.
SET TELNET PORT 23
Sets the Telnet port to “23” (default
port).
Syntax:
SEND_COMMAND <DEV>,"'SET TELNET PORT 23'"
Example:
SEND_COMMAND dvRX,"'SET TELNET PORT 23'"
Note: A reboot is required after sending the SET TELNET PORT 23 command.
SEND_STRING Escape Sequences
Command Description
27, 17
Send a break character for
a specified duration to a
specific device.
Syntax:
27,17,<time>
Valid response:
time = 1 to 255 (measured in 100 microsecond increments)
Example:
SEND_STRING RS232_1,"27,17,10"
Sends a break character of 1 millisecond to the RS232_1 device.
27, 18, 0
Clear the ninth data bit by
setting it to 0 on all character
transmissions.
Used in conjunction with the 'B9MON' command (see page 92).
Syntax:
27,18,0
Example:
SEND_STRING RS232_1,"27,18,0"
Sets the RS232_1 device’s ninth data bit to 0 on all character transmissions.
27, 18, 1
Set the ninth data bit to 1 for
all subsequent characters to
be transmitted.
Used in conjunction with the 'B9MON' command (page 92).
Syntax:
27,18,1
Example:
SEND_STRING RS232_1,"27,18,1"
Sets the RS232_1 device’s ninth data bit to 1 on all character transmissions.
27, 19
Insert a time delay before
transmitting the next
character.
Syntax:
27,19,<time>
Valid response:
time = 1 to 255. Measured in 1 millisecond increments.
Example:
SEND_STRING RS232_1,"27,19,10"
Inserts a 10 millisecond delay before transmitting characters to the RS232_1 device.
