To use the RS-232 port, connect the RS-232 input (Female) connector to your

To daisy chain splitters, use a M/M HDMI connector to connect HDMI-OUT from
the first unit to the HDMI In of the down-stream box.
If RS-232 is used, connect the RS-232 OUT connector to RS-232 IN of the next
box. Remember that when more than one unit is daisy-chained, you must assign
the addresses for each the outputs so they can individually address a particular
RJ45 and send out a command via RS-232 to the remote receiver.

NOTE
By default, the output port numbers are assigned address 1
through 3. (Or 1 through 6). To assign a different range, the
user must connect the Splitter to a PC using the supplied USB
cable and use the appropriate "UHBX-3S or 6S Manager
Software" from the Hall Research website.
