Connector Description
SERVICE For use by Service personnel only
Using the SY-HDBT-662
Up to four HDMI sources, one DisplayPort source and one VGA source may be connected to the
SY-HDBT-662. Each of these inputs can be independently selected to the two output zones. The
output connectors in a single Zone will all show the same input signal, but each output Zone can
show different inputs.
For example, the HDMI and HDBaseT outputs in Zone 1 can all be showing HDMI input 2, while the
HDMI and HDBaseT outputs in Zone 2 are showing HDMI input 4.
The Zone 1 L+R Audio Output will output the audio from the selected input for Zone 1, and the Zone
2 L+R Audio Output will output the audio from the selected input for Zone 2. So, using the above
example, Zone 1 Audio Out will have the de-embedded audio from HDMI input 2, and Zone 2 Audio
Out will have the de-embedded audio from HDMI input 4.
The input selection to each Zone may done using any of the following control methods:

Front Panel buttons

RS232 commands

Ethernet port

I/O Control
RS232 and IR control signals can also be passed between the HDBT-662 and the connected
HDBaseT receivers.
Front Panel LED Indications
The front panel selection LEDs (and those on the external switch box, if fitted) provide feedback on
the input signal status:

A valid input signal is indicated by a solid LED

A no signal state is indicated by a flashing LED
Using an External Switches
The SY-HDBT-662 has an interface for Input selection, using simple external Push Button switches,
as shown in the following schematic:
For each connector, pin 1 is left-most when viewed from the rear of the HDBT-662.
