HDMI to HDBaseT Splitter
with
Audio De-Embedder

SY-HDBT-282-S
www.sy.co.uk 2V1.0
The SY-HDBT-282-S takes two HDMI inputs and splits the selected input equally to all
eight HDBaseT outputs as well as to both HDMI outputs. This switch splitter allows any
source to be shown on any of the connected displays, these sources can include
BluRay or UHD BluRay players, satellite receivers, gaming consoles, or PCs.
RS232 and IR control is also routed to all HDBaseT outputs allowing control of the
switch splitter, the source device, or the display device.
The HDMI from the selected input is also de-embedded to analogue stereo, optical
S/PDIF and coaxial S/PDIF
Features
Switches between two HDMI input sources
Splits the selected input to eight HDBaseT outputs and two HDMI outputs
Advanced EDID management
Supports HDMI 2.0
Supports HDMI resolutions up to 4K60 4:2:0
IR and RS232 control options
IR and RS232 routed to all HDBaseT outputs

Operation of the SY-HDBT-282-S
The SELECT button on the front panel switches between the two HDMI inputs. The
selected input then appears on the two HDMI outputs as well as the eight HDBaseT
outputs, but the signal is only presented if there is an HDMI sink device connected to
either or both the HDMI outputs or to any HDBaseT output that has an HDBaseT receiver
with an HDMI sink device attached to the receiver.
Any output that has a valid sink device connected will be indicated by a blue LED on the
front panel for that output.
EDID Management
EDID management allows you to set a specific EDID default to ensure a certain
resolution is being sent from a HDMI source. The EDID setting can be different from
each input.
The following procedure detail how to use the EDID Management function:
1. Press the SELECT button to select the input to program, HDMI 1 or HDMI 2.
2. Press and hold the SELECT button for three seconds to enter the EDID
Management mode. Both the HDMI output LEDs will start to flash.
3. The first five HDBT output LEDs indicate the EDID option according to the
following table, press the SELECT button repeatedly until the desired setting
is displayed by the LEDs:

within that time.
RS232 Commands
The SY-HDBT-282-S can also be controlled or configured using RS232 commands. The
RS232 settings for control and configuration commands are:
57600 baud, no parity, 8 data bits, and 1 stop bit.
The default address of the SY-HDBT-282-S is 00. If this address is not 00 then each
RS232 command must be preceded by Azz, where zz is the address of the SY-HDBT-

SY-HDBT-282-S
V1.0 5www.sy.co.uk
282-S you wish to control.
All commands are in ASCII, are not case-sensitive and are always terminated by a
carriage-return (0x0d) character.
Control and configuration of the SY-HDBT-282-S is only possible when the RS232
bypass mode is set to its disabled state (SET RS BP 1).
Upon power-up, the SY-HDBT-282-S will output the following RS232 text. Note that this
text will vary as it is dependent upon the installed software version.

Help
RS232 Command: H
This command generates a list of all the available RS232 commands with a brief
description for each command.
Status
RS232 Command: STA
This command outputs the current status of the SY-HDBT-282-S, the status info for the
HDMI inputs, HDBaseT outputs (OUT01 to OUT08 in the status report) and the two HDMI
outputs (OUT09 and OUT10 in the status report).
For each output the following information is included: The selected input, HDCP status,
and whether there is a link to a Slim 70 Rx receiver unit.
RS232 Command: GET STA
This command outputs a shorter version of the status report that is easier for a computer
program to parse as it does not produce the page formatted layout of the STA command.
Set System Address
RS232 Command: SET ADDR xx
Use this command to change the device address of the SY-HDBT-282-S where xx is
decimal value in the range 00 to 99. This command should be used with caution as any
address other than 00 will require the address value before any RS232 command. The
address prefix is Axx, where xx is a decimal value in the range 01 to 99.
Get System Address
RS232 Command: GET ADDR
RS232 Response: ADDR xx

SY-HDBT-282-S
www.sy.co.uk 6V1.0
Where xx is the actual address of the device in the range 00 to 99. The factory default
value is 00.
Set RS232 Bypass Mode
RS232 Command: SET RS BP x
RS232 Response: RS BP x
Where x is either 0 to enable RS232 bypass mode or 1 to disable RS232 bypass mode.
Bypass Enabled
In this mode the HDBT-282-S will only respond to the SET RS BP 1 command. All other
control commands are ignored and no RS232 data is passed through to the Slim 70 Rx
receiver unit.
Bypass Disabled
In this mode, the HDBT-282-S will respond to all its control commands and pass through
all commands through to the Slim 70 Rx receiver unit. This is the factory default mode.
Get RS232 Bypass Mode
RS232 Command: GET RS BP 1
RS232 Response: RS BP x
Where x is the 0 when bypass mode is enabled or 1 when bypass mode is disabled.
Select Input for All Outputs
RS232 Command: SET OUT 0 VS INx
RS232 Response: OUT 0 VS INx
Where x is either 1 or 2 for the desired input number.
This command selects the desired input to show on all outputs. Note that all outputs will
always show the same input source selected by this command.
Get the Selected Input Number
RS232 Command: GET OUT 0 VS
RS232 Response: OUT 0 VS INx
Where x is either 1 or 2 for the desired input number.
Set the Output HDCP Mode

the specified output.
When z is 0, the output HDCP mode to auto, where it follows the HDCP mode of the
input source device. When z it 1, the output HDCP mode is disabled.
Get HDCP the Output Mode
RS232 Command: GET OUT y HDCP
Where y is in the range 0 to 10. 0 means get the HDCP status for all outputs together
(10 lines) and 1 to 10 means get the HDCP status for the specified output only (1 line).
Set External Audio Status
RS232 Command: SET OUT 0 EA x
Where x is either 0 to turn off the audio de-embedder, or 1 to enable the audio de-
embedder.
All three external audio outputs, when enabled, each output the same audio signal from
the selected HDMI input.
Get External Audio Status
RS232 Command: GET OUT 0 EA
RS232 Response: OUT 0 EA x
Where x is either 0 if the audio de-embedder is off, or 1 if the audio de-embedder is on.
The factory default is on.
Set Input EDID Data
RS232 Command: SET IN x EDID y
RS232 Response: INx EDID y
Where x is either 1 or 2 for the desired input number, and y is in the range 0 to 14 (in
decimal).
This command sets one of the 12 factory defined EDID data sets, or one of the three
user data sets. Each user data set are factory set to contain a valid EDID data block, but
they can be re-programmed by either the SET INx EDID CY OUTy command for
USER1 EDID memory only, or the SET INx Uy DATAz RS232 command for any of
the three USER memory locations.
Please note that each input may be set to different EDID settings

Copy EDID Data from an Output to an Input USER1 Memory
RS232 Command: SET IN x EDID CY OUT y
Where x is one of 0, 1 or 2 for the desired input number, and y is in the range 1 to 10.
When x is 0, the USER1 memory of both inputs receives the copied data from the
specified output. For this command only one output can be specified as the source for
the EDID data to copy.
Write EDID Data to the User Memories
RS232 Command: SET IN x EDID Uy DATA <z>
Where x is either 0 or 2 for the desired input number, and y is in the range 1 to 3 for the
desired User memory.
When x is 0, the USERy memory of both inputs receives the data specified by z.
For this command <z> must contain 256 bytes of a valid EDID data block. The data block
is specified in ASCII hexadecimal notation with each byte value separated by one space
character (0x20). Programming invalid data will produce an incorrect video format, or
the HDMI source may not produce any output at all.
Get the Current EDID Memory Index Value
RS232 Command: GET IN x EDID
RS232 Response: INx EDID y
Where x is one of 0, 1 or 2 for the desired input number, and 0 means get the index

Set IR Codes
Set IR System Code
RS232 Command: SET IR SYS xx.yy
RS232 Response: IR SYS xx.yy
This command sets the common values that prefix every IR command intended for the
SY-HDBT-282-S. The values for x and y are in ASCII hexadecimal notation and must
match the codes of the IR controller that is to be used to control the input selections. The
factory default values for x and y are 00 and FF.

RS232 Response: IR OUT 0 IN x Code yy
Where x is either 1 or 2 for inputs 1 and 2 respectively, and y is an ASCII hexadecimal
value in the range 00 to FF that represents the command code value to select the desired
input. To ensure correct operation of the SY-HDBT-282-S, the Code y values for input 1
and input 2 must be different. The factory default values are 57 for input 1, and 41 for
input 2.
