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 are as follows:
Switch Command + Output Command + Port Number (at first stage) + Port
Number (at second stage) + Port Number (at third stage) + Control [Enter]
For the example above, the command for switching off the Target Output Port
4 of 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 [Enter]
This cascade command format is applied to Mute Commands, page 15, Read
Commands, page 17, and Reset Commands,page 18. However, this is not
applicable to EDID commands, which apply only to the first stage unit splitter,
as well as the Firmware commands.
