AT-UHD-CAT-4 23
In pass-through mode, RS-232 commands are passed-through the AT-UHD-CAT-4, transmitted over HDBaseT to a
receiver unit, and then to the display (sink) device. Note that each RS-232 / IR port is assigned to an HDBaseT OUT
port. This assignment is fixed and cannot be changed, as shown in the table below.

LEARN
1. Connect the RS-232 cable from the control system to the desired RS-232 / IR port on the AT-UHD-CAT-4.
Refer to Cable Assembly (page 22) for instructions on preparing the cable.
2. Connect an Ethernet cable from the desired HDBaseT OUT port to a receiver. In this example, the HDBaseT
cable is connected from HDBaseT OUT 2 to an AT-UHD-EX-70C-RX receiver (the RS-232 cable is connected
from the control system to the RS-232 / IR 2 port).
3. Connect an RS-232 cable between the display (sink) and the receiver.
4. Adjust the RS-232 settings on the control system to match the requirements of the sink device. For example, if
the RS-232 settings for the display device are 9600, N, 8, 1, then set the control system to the same settings.
If the control system and sink device settings do not match, then RS-232 control will not function.
