AUTO| Signifies auto detection mode is active
SELECT button| Input selection for HD1 & HD2. > 3s for Auto mode

Rear Panel

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.

EDID Switch Settings

The four-way switch on the rear of the SY-HDBT-231 provides twelve fixed EDID settings, one programmable setting and three EDID copying modes. The switch settings are given in the following table. (Switch position: U = Up, D= Down)

EDID

7| U D D D| 4K@30Hz 3D 6CH| –| D D D D 1| 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:

SY-HDBT-

231

| DE-9 Pin
---|---
TX| 2
Gnd| 5
RX| 3

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.
