Hall Research Technologies UHBX-8X, User Manual

8-Port HDMI Extender with Power, IR, and RS-232

To generate IR commands using RS232 or IP commands, the user must know
the protocol (NEC, Sony, RC5, etc), IR address, and IR command bytes. If
these are not known the UHBX does provide the means to send “learned” IR
codes, but to learn the codes a Hall Research model HR-4P may be needed.
The IR send command for “learned” codes are typically a series of 64 Hex
bytes that precisely define the IR signal to be generated.

If there are IR detector cables plugged in at the remote receivers, those signals
are extended to the UHBX-8X and are available at the IR Output connectors.

IR Detector Cable
The UHBX-8X uses “pass-thru” IR detector cable that maintains the IR
modulation. Compatible cables are available from Hall Research (Model
Number CIR-DET-P2). Pin out: Tip=Data, Ring=+5V DC, Sleeve=GND
