The SY-HDBT-231-70 and SY-HDBT-231-100 provide a selection from one of two HDMI input
sources and distributes that selection to three HDBaseT outputs and a local HDMI output. The
HDBaseT outputs can respectively broadcast up to 70m / 100m @ 1080p or 40m / 70m @ 4K
30Hz using cat6a cable (using SY-HDBT-70-SLIM-R or SY-HDBT-100-SLIM-R receivers).
Features
2x selectable HDMI inputs
3x HDBaseT outputs
1x HDMI output
All outputs show the same HDMI input selection
De-Embedded audio output
RS232 and IR control through the HDBaseT outputs
Controllable from front panel or via RS232 commands
EDID Management
PoC on HDBT outputs. Each port can power a receiver unit

Using the SY-HDBT-231-70 / 100
1. Connect the two HDMI inputs to any HDMI sources. Connect to the HDBaseT and Local
HDMI outputs as needed. The HDBaseT outputs should be connected to the receivers
using Cat6 cabling to ensure the best signal quality over the maximum cable length.
2. Connect the 48V power supply.
3. Use the SELECT button to switch between the two HDMI inputs.
Using the Auto-Detect Mode
Hold down the SELECT button until the AUTO LED lights up (~3S) – Auto-detection enabled.
Hold down the SELECT button until the AUTO LED goes out (~3S) – Auto-detection disabled.
When in Auto mode, the unit will automatically switch to a newly active HDMI input and will fall
back to the other active input if no signal on current selection detected.
When in Manual mode (Auto off), either input can be selected regardless of being active or not.

Set Cascade Mode
Notes:
1. These three settings are commands and should not be used as EDID settings. When the switch is
set to these commands, the EDID remains as the last valid EDID setting until another EDID setting
is chosen.
2. The USER 1 EDID Memory can also be programmed using the appropriate RS232 command, see
the RS232-CTL Commands section for details of this command.
3. The Copy from Output 1 switch setting reads the EDID data from the display device connected to
the HDMI output to the User 1 EDID memory of both inputs.
4. The Copy from 1st Connected Output switch setting will copy the EDID data from the first display
device that is connected to the SY-HDBT-231 to the User 1 EDID of both inputs. This can be from
either the HDMI output or any of the HDBT outputs.
Cascade Mode
Cascade mode can be enabled/disabled via RS232 commands (SET CAS EN, SET CAS DIS), using
RS232-CTL port. This may speed up the overall system switching speed when several devices
are cascaded together (such as HDBT-231 to MSUHD88 to Apollo 4K to…).
Be sure to wire the RS232 connections correctly when using D-type connectors, as given in the
following table:

RS232-CTL Commands
All commands are sent at 57600 baud, 8 data bits, no parity and one stop bit.
Commands are not case sensitive, but must always be followed by a carriage-return (0x0d).
All responses are in uppercase and provide an acknowledgement of the command or reply
with the requested data, and are terminated with a carriage-return & line-feed (0x0d 0x0a).

RS232
The RS232 port is a direct data pass-through to the HDBT outputs.
The Tx data are broadcasted to all the remote receivers (via HDBT 1, 2, 3); whilst the Rx
receives data only from the HDBT 1 port.
IR IN / OUT
By attaching an IR eye (receiver) to the IR IN connector, IR signals from a remote controller can
be broadcasted to all the HDBT outputs.
All the IR signals from the remote HDBT receivers are summed together and brought to the
IR OUT connector. Connect an IR emitter (blaster) to this port for controlling a local device.

Note: You may use cat5e, cat6 UTP in conjunction with the HDBaseT outputs; however for best
performance use cat6a or cat7 (particularly in electrically noisy environments). The maximum
distances & transmission performance for HDMI and HDBT may be compromised by cable
quality, patch panels, poor termination, wall plates, cable kinks and electrical interferences.
Generally ensure the cat cable is solid copper core (avoid CCA type), in one straight run
(avoid/minimise patches) and avoid close proximity to any noisy electrical sources.
