The 4K Ultra HD Extender w/ RS-232 and 2-way IR supports RS-232 pass-through,

allowing the control of remote RS-232 devices. The Sender and Receiver unit which are

being used to pass-through the RS-232 data must be set to the same baud rate as the

RS-232 host and client. The example, below, shows a sample application. The video

cables have been removed for clarity.

Figure 2.1 - Sample RS-232 connection

1. Connect the RS-232 automation device to the desired Sender unit.

2. Connect the RS-232-controlled display (or other RS-232 device) to the Receiver unit.

3. Set the required baud rate using the DIP switches on the bottom of the Sender unit.

Consult the User Manual for the client device for the proper RS-232 settings.

See Baud Rate (page 16) for more information on setting the DIP switches.
