RS-232 Serial Interface

The VM0404H’s built-in bi-directional RS-232 serial interface allows system control through a high-end controller, PC, and/or home automation / home theater software package.

Configuring the Serial Port

The controller’s serial port should be configured as follows:

Baud Rate

19200

 

 

Data Bits

8

 

 

Parity

None

 

 

Stop Bits

1

 

 

Flow Control

None

 

 

Switch Port Commands

The formula for Switch Port commands are as follows:

Switch Command + Input Command + Port number + Output Command + Port Number + Control + [Enter]

1.For example, to switch input port 02 (audio and video) to output port 03, type the following:

sw i02 o03 [Enter]

2.To turn off video and audio on port 03, type the following: sw o3 off [Enter]

3.To switch the next output to port 2, type the following: sw i02 + [Enter]

The following tables show the possible values for commands:
