4.2 EDID Management
One of the distinguishing features of the UHBX-3S is EDID management. It
supports two modes of operation Pass-Through & Emulate. In Pass-through
mode the EDID of the TV connected to the output(s) is passed to the source. In
Emulate mode the UHBX-3S allows the user to send an EDID table that is stored
in the splitter itself (independent of the sinks). The EDID mode is selectable from
the front panel. The internal EDID table can be modified in two ways.
1. It can be "learned" from the display connected to the local HDMI output (by
holding the SEL button for 5 seconds, or using the GUI software
2. The user can upload any valid EDID table from a PC through the USB port
To switch between EMULATE and PASS-THRU modes, simply press the SEL
button. To "LEARN" the EDID from locally connected TV press and hold the
SEL button for 3 seconds.

5.0 Serial (RS-232) Commands
The UHBX-3S has special commands that can be used to selectively send data to
the HDBaseT outputs. This section describes serial port settings, command
syntax and expected response from the unit.
Note - If daisy-chaining more than one box, prior to using serial commands
please assign a unique port number to each output port using the UHBX-3S
Manager Software. Please refer to the software guide for more details.
5.1 Serial Setup
Connect one end of M/F serial (RS-232) cable shipped with the product to the
RS-232 In port of UHBX-3S and the other end to the RS-232 port of your
computer (or USB to RS-232 adapter). Open a serial terminal program (e.g.
HyperTerminal or Realterm, TeraTerm etc.) and set up the serial port using the
following settings.
Baud Rate: 19200, Bits: 8, Parity: None, Stop Bits: 1, Flow Control: Off
PASS Solid On means current EDID configuration is in Pass-Thru mode
EMUL Solid On means current EDID configuration is in EMULATE mode
Blinking means the selected mode is Pass-Thru (PASS LED will be solidly
lit), but the splitter could not find any sinks at any of its 4 outputs so it has
decided to emulate EDID from internal table. In this case as soon as you
plug a display to any of the 4 outputs, the EMUL LED will stop blinking
