SY-SE-10
18G HDMI 2.0 Up/Down Scaler (with image Enhancer),
EDID Manager, HDCP controller
& Audio De-embedder

sy.uk 2V1.2
The SY-SE-10 provides HDMI image scaling for both 2K to 4k (upscaling) and 4K to 2K
(downscaling), with image enhancement settings in the upscaling mode. The SE-10 has a wide
range of EDID settings that should cater for most situations, including a programmable EDID
setting for those more troublesome times. It also provides two test patterns at 1080p and 4K30
that can be very useful for commissioning and system test.
The EDID management provides the installer/integrator with 14 fixed EDID settings (including
HDR and Audio modes), an EDID bypass mode and one programmable EDID location. This make
the SE-10 extremely versatile in being able to cope with any HDMI EDID related issues.
The SE-10 also De-embeds the incoming audio to stereo L/R analogue audio that may be used
for either checking the audio signal or connection to a stereo power amplifier system.
All these powerful features are provided in a small package that can be discretely located.

Using the SY-SE-10
The SE-10 is placed in between the HDMI output device (Source) and the HDMI display device
(Sink) and powered via the mini USB connector by the supplied PSU - see Figure 3.
The switches provide the various options for EDID settings, Scaling mode and Scaling
Enhancement options. These are detailed on the top of the SE-10, but are also reproduced in
the following tables. For each of the tables, arrow up (↑) means that the switch is in the UP (0)
position and arrow down (↓) means that the switch is in the DOWN (1) position.

EDID Settings
The choice of EDID setting should always be determined by the requirements of the installation
as some setting are not compatible with the HDMI display device being used in a specific
situation. The following table applies only to the 4-way EDID switch.

User EDID
User programmable EDID memory
Programming USER EDID memory Using S6
S6 switch can be used to program the USER EDID memory location as follows:
1. Set all four EDID switches to ON (↓), and ensure S6 is set to OFF (↑).
2. Ensure there is an HDMI sink device connected to the HDMI OUT connector.
3. Set S6 to ON (↓).
4. Within 2 seconds set S6 to OFF (↑), the USER EDID memory is now programmed with
the EDID data read from the HDMI sink device and is ready for use.

Using the Scaler and Enhancement Modes
The Scale and Enhance switch settings are used together to provide either image upscaling
(2K→4K) or downscaling (4K→2K). The upscaling mode may also employ one of three
enhancement modes.
Note: The scaler function only affects the number of pixels and scan lines, the refresh rate
remains unaffected by the scaler setting.
Enhancement Mode Settings
Care should be used to determine the amount of image enhancement is required when using
the 2K→ 4K scaling mode, as too high a setting could make the image quality seem worse. Always
start with the Weak setting and move up from that setting until the desired image quality is
achieved.

HDBT Modes
The two HDBT modes are used to optimally limit the bandwidth when using HDBaseT extenders,
these two modes provide the following options:
HDBT Mode 1 – See Figure 4
4K30 resolutions with colour bit depths of 10 or 12 bits are reduced to 8 bits to keep the
bandwidth below 10.2Gbps. This resolution can be connected directly to the HDMI sink device.
Since this mode outputs a reduced colour specification there will be some loss of information.
HDBT Mode 2 – See Figure 5
Any 4K30 resolution with colour bit depths of 10 or 12 bits are maintained with the same colour
bit depth but the sub-sampling is reduced to 4:2:0 to keep the bandwidth below 10.2Gbps. With
these settings the HDMI signal is non-standard and cannot be directly connected to the HDMI
sink device. A second SE-10, also set to HDBT Mode 2, is required after the HDBaseT receiver to
restore the video to a standard HDMI mode that can be connected to the HDMI sink device.
In this mode, with certain resolutions and settings, there will be NO loss of image quality.
Test Patterns TP1 and TP2
The SE-10 also provides two test patterns at either 1080p60 or 4K30 (3840x2160 @ 30Hz). Note
that for 1080P the White to black stripes are repeated twice; whilst in the 4K30 mode they are
repeated 5 times. The following two images and the table below illustrate the differences
between the patterns:

RS232 Control
When the SE-10 is powered from a PC USB port, the PC will also recognise the SE-10 as having a
serial port. Use the following settings to send commands to the SE-10:
Baud Rate: 57600
Data Bits: 8
Parity Mode: None
Stop Bits: 1
Commands are not case-sensitive, but must always be terminated with a carriage-return <0x0d>
character. Any command may be typed manually using any terminal emulation software or from
the RS232 serial output port of some other control equipment.
All response messages are always in uppercase and are also terminated by a carriage-return and
line-feed character pair, <0x0d> + <0x0a>. Command response messages are also transmitted
whenever the front panel switches change, thus keeping other systems up to date on any recent
changes.
The following sections detail the available commands for the SE-10:
H – (Help)
Purpose: Get the command help text
Command: H
Response: A text listing of all available commands.
STA and GET STA – (Status)
Purpose: Get the current status info in either a detailed or simplified format.
Command: STA
Response: A text file detailing the current status of the SE-10. The output from this
command contains textual descriptions of the SE-10 status.
Command: GET STA
Response: A simpler listing of the current status of the SE-10. The output from this
command lists normal command response messages as follows:
Response Text
Description
ADDR 00
The current address of the SE-10
OUT HDCP 0
The current output HDCP mode
OUT1 VIDEO 0
The current scaler mode
OUT1 IMAGE ENH 0
The current image enhancement mode
OUT1 EXA EN
The current External Audio mode
OUT1 SGM DIS
The current test pattern signal generator mode
OUT1 SGMT 0
The current test pattern signal generator resolution setting
IN1 EDID 0
The current EDID setting for HDMI IN
The values shown above are those given when all the option switches are OFF. The actual values
will depend on the current settings of the SE-10 before the GET STA command is sent.
Note: The status information may be updated either by RS232 commands or by changing the
switches on the front panel. The status information will always be from the last change of state
that occurred before the get status request was made.
