RS-232 Control Tool Operation
Overview
The VS0102 / VS0104 / VS0108’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. The RS-232 Control Tool is an
application used to send operational commands from your PC – to the VS0102
/ VS0104 / VS0108 through a serial (RS-232) interface connection. RS-232
serial operations to and from the VS0102 / VS0104 / VS0108 can be managed
using ATEN’s Graphical User Interface (GUI) on computers that are running
the Microsoft Windows operating system. In order to use the RS-232 Control
Tool, two separate programs must be installed on the PC- .NET Framework 2.0

Switch Command for Cascaded Splitters
Serial port commands for cascaded splitters require identifying the chain of
ports to which the target device is connected. The formula for Switch Port
commands in a cascade are as follows:
Switch Command + Output Command + Port Number (at first stage) + Port
Number (at second stage) + Port Number (at third stage) + Control
For the example above, the command for switching off the Target Output Port
4of the splitter connected to Port 3 at the second stage of the cascade, which,
in turn, is connected to output Port 4 at the first stage unit, is as follows:
sw o04-03-04 off
This cascade command format is applied to Mute Commands, page 17, Read
Info Commands, page 20, and Reset Commands, page 23. However, the
cascade commands are not applicable for the Version or EDID commands,
which are only applied to the first stage unit.
