The HD over IP 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.
In the example below, a display is connected to Receiver unit R1. This is the RS-232 client.
We want to control this product from Sender unit S3, using an automation device (host).
The channel numbers are listed in blue. The RS-232 data is shown in orange. The video
signals have been removed, from the diagram, for clarity.

1. Connect the RS-232 automation device to the desired Sender unit.
2. Connect the display (or other RS-232 device) to the desired Receiver unit.
3. Consult the User Manual for the client device for the proper RS-232 settings.
For example, our display device requires the following RS-232 settings:
