32 AVX-400 Enova Twisted Pair Presentation Switcher Operation/Reference Guide
AxLink Commands (Cont.)
RXOFF Disable the transmission of incoming received characters to the Master. This option is disabled by
default.
Syntax:
SEND_COMMAND <DEV>,"'RXOFF'"
Example:
SEND_COMMAND dvRXRS232,"'RXOFF'"
Stops the Rx serial device from transmitting received characters to the Master.
RXON Enables sending incoming received characters to the Master. This command is automatically sent by
the Master when a 'CREATE_BUFFER' program instruction is executed. The end device does not
transmit characters to the Master unless this command is activated on the device. The AVX-400 must
be in passthru mode to execute this command.
Syntax:
SEND_COMMAND <DEV>,"'RXON'"
Example:
SEND_COMMAND dvRXRS232,"'RXON'"
Sets the Rx serial port to transmit received characters to the Master.
SET BAUD Set the serial communication parameters.
Syntax:
SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,<stop>'"
Variables:
baud = baud rates are: 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200.
parity = N (none), O (odd), E (even).
data = 7 or 8 data bits.
stop = 1 and 2 stop bits.
Example:
SEND_COMMAND dvRXRS232,"'SET BAUD 9600,N,8,1'"
Sets the display port's communication parameters to 9600 baud, no parity, 8 data bits, 1 stop bit.
SSW Simulates pressing the select switch. Pressing the source select button activates the next valid
source input. This command simulates a single pressing of the source select button on the
presentation switcher.
Syntax:
SEND_COMMAND "’SSW’"
?TEMP Queries the temperature status on the display; returns the current temperature status.
Syntax:
SEND_COMMAND "'?TEMP'"
Sample Output:
"Temperature = xxxx"
where xxxx = temperature
If the system temperature cannot be determined:
"Temp = Unknown"
