CHAPTER 7: RS-232 CONTROL

7.3.10 THIRD-PARTY DEVICE CONTROL 

 

The switcher supports RS-232 pass-through control. A third-party device can be controlled by an RS-232 command, and the command 
format is shown next.

TABLE 7-12. THIRD-PARTY DEVICE CONTROL

  COMMAND

  FUNCTION

COMMAND EXAMPLE

  UARTPassThrough:Y.

  RS-232 mode selection:
  •  Y=0, Local Control: The RS-232 port of the switcher is used to connect a control 

device (e.g. PC) to control the switcher.

  •  Y=1, HDBT Transmitter Pass Through: Establish RS-232 pass-through 

communication between the switcher and the HDBaseT transmitter (e.g. VX-
HDB2-TX). The RS-232 port of the switcher can be used to transfer commands to 
control the third-party device that is connected to the HDBaseT transmitter.

  •  Y=2, HDBT Receiver Pass-through: Establish RS-232 pass-through communication 

between the switcher and HDBaseT receiver (e.g. VX-HDB2-RX). The RS-232 port 
of the switcher can be used to transfer commands to control the third-party device 
that is connected to the HDBaseT receiver.

  /+[X]/[Y]:xxx.

  xxx: ASCII characters.
  • Y: Represents the RS-232 port.
    1.  Y=1: The RS-232 port of switcher.
    2. Y=2: The RS-232 port of HDBaseT receiver.
    3. Y=3: The RS-232 port of HDBaseT transmitter.
  • X: Represents the baud rate of the third-party device.
    1. X=1, 2400
    2.  X=2, 4800
    3. X=3, 9600
    4. X=4, 19200
    5. X=5, 38400
    6. X=6, 57600
    7. X=7, 115200

   Send the command 

“123456” to the third-party 
device. The baud rate is 
9600.
