Basic Operation
RS-232 Control
The AT-UHD-HDVS-300-KIT provides an RS-232 port on both the transmitter and the receiver. There are two modes
of RS-232 control: Pass-through and display control.
It should be noted that the AT-UHD-HDVS-300-KIT cannot be controlled using RS-232. Direct control of the
AT-UHD-HDVS-300-KIT is only supported through the TCP/IP protocol.
In pass-through mode, an automation control system is used to control an RS-232 device. The most common
configuration is connecting a control system to the
RS-232
port on the transmitter and the device to be controlled to
the
RS-232
port on the receiver. However, RS-232 is bidirectional, which allows the control system to be connected
to the receiver and the device to be controlled to the headend (where the sources are located).
