Thank you for purchasing the Slim70-Pro Extender Set.
This HDBaseT extender is designed with the professional AV installers in mind. The many
extensive features assist in system integration, validation and maintenance. It is still the
slimmest HDBaseT extender in the world with tremendous flexibility and extraordinary
capabilities.
Installation precautions
This product has special circuitry to protect it against moderate surges and static discharges.
However, to ensure reliable operation and long service life, it is important to take the
necessary precautions against any spikes, surges and static discharges.
Place the units away from heat sources and allow adequate ventilation.
Shielded cable and in particular cat6, cat6a or cat7 is highly recommended. As much as
possible cables should be routed away from any noisy sources and avoiding long runs in close
proximity to mains cables.

sy.uk 4V1.0
The Slim70-Pro HDBaseT Extender set supports all input resolutions to 4K60 4:4:4, with bi-
directional IR, and two independent pass-through RS232 ports. The main RS232 channel (Tx/Rx)
is also used for controlling the many features. The second RS232 channel (T2, R2) can also be
used for RTS/CTS handshaking.
The transmitter unit (SY-HDBT-70SP), also supports de-embedded audio (L/R and Mini-Toslink
optical output), as well as many useful features such as: HDCP management, EDID settings, video
Down-Scale, Test Patterns, Video Keep Alive, Temperature & CEC control, diagnostics.

Independent second RS232 (pass-through) data port for any
baud rate up to 57600. These can also be used as RTS/CTS
handshaking lines, see Figure 1.
Mini Toslink – (SY-HDBT-70SP-T)
L/R Analogue Audio Output
3.5mm Stereo Jack. 20Hz – 20kHz, 1.5Vrms max
Mini- Toslink – Optical S/PDIF Audio Output
Notes:
1. The RJ45 connector shielding ensures proper utilisation of full STP/FTP cat cables, such as
cat-5e STP or cat-6a. Shielded cat cables are recommended for noisy environments.
2. The iPoC function ensures safe powering of the remote unit. In this way only one PSU is
required at either the Transmitter or Receiver end. The iPoC circuitry interrogates the
remote device and delivers 48V power only if a compatible device has been identified;
otherwise it does not provide any power. In this way it is much safer to connect to other
HDBaseT devices such as projectors with built-in HDBaseT.
3. Extracted Audio output is available as Analogue L/R (3.5mm stereo), as well as optical
Mini-Toslink (S/PDIF).

Using the SY-HDBT-70SP-T and SY-HDBT-70SP-R
Connect a video source to the Transmitter (SY-HDBT-70SP-T) HDMI input connector and
the remote display device to the Receiver (SY-HDBT-70SP-R) HDMI output connector.
Ensure the catx cable is wired correctly – see RJ-45 Wiring for connection details.
Plug the cat5e/6/6a cable into the RJ45 jacks of Transmitter and Receiver units.
If needed, connect any optional inputs and outputs such as audio, IR or RS232.
Power up the extender by connecting the 48V DC power adaptor to either Transmitter or
Receiver unit – Only one PSU required with iPoC function (intelligent PoC).
Audio connection can be made with either 3.5mm Stereo jack (L/R), or optical Mini-Toslink
using the combi port on the Transmitter unit.
For simple RS232 pass-through communication use Tx Rx lines. These lines are also used
for controlling the Slim70-Pro units (see RS232 Control Commands).
When RTS/CTS handshaking is also required, connect R2 to RTS and T2 to CTS of the control
device, as shown in the following wiring diagram:
Figure 1 - RS232 Wiring with optional RTS/CTS Handshakes
Slim70-Pro can support two independent RS232 channels. T2/R2 can be used as a second
independent pass-through RS232 channel, as per below diagram:
Figure 2 - Dual Independent RS232 Wiring
If the R2/T2 terminals are not required, they can be left as not connected.

RJ-45 Wiring
Both connectors must be wired identically.
HDBaseT signals will NOT pass through any Ethernet device, the HDBaseT port on the SY-HDBT-
70SP-T must be connected directly to the HDBaseT port on the SY-HDBT-70SP-R.
Please do make sure that the Cat6 cable uses 4 pairs of 23AWG solid copper wires. Do not use
inferior copper clad cables as these exhibit much higher resistances.
Test Pattern and Keep-Alive Features
The Slim70-Pro extenders also provide a built-in Test Pattern generator that is useful to verify
the integrity of connections from the transmitter through to the display device. Several test
patterns at different resolutions are provided. See Test Pattern in the RS232 Control Commands
section. Test pattern can be generated using the transmitter front panel switch (TP).
The Video Keep Alive (No Signal Handling) feature also uses the saved test pattern setting,
ensuring a video signal is always present at the receiver HDMI output in the event of input video
loss.
See Video Keep Alive (No Signal Handling) in the RS232 Control Commands section.
Down-Scaling
The Slim70-Pro transmitter can accept 4K50/4K60 4:4:4 (18G) HDMI 2.0 signals. The built-in
down-scaler ensures appropriate scaling to maximum HDBaseT bandwidth of 10.2G, whilst
providing compatibility with of the display unit. Three scale options are available as per below:
1. Down-Scale any 4K resolution to 1080p
2. Convert 4K60 4:4:4 signals to 4K60 4:2:0 (colour-space conversion)
3. Auto: Provides optimal resolution / colour-space option, based on cable length and
display capability.
See 4K Down-Scaling in the RS232 Control Commands section.
Connecting to the IR Ports
The IR IN and IR OUT ports on the rear of the Transmitter/Receiver units may be used to send IR
remote control data between the two units. The following table details the wiring connections

RS232 Control Commands
The many features of Slim70-Pro transmitter/receiver units can be managed using RS232
commands (Tx, Rx port). The ASCII commands given in this section use the following port settings:
Baud Rate: 57600
Data Bits: 8
Parity: None
Stop Bits: 1
Notes:
1. All commands in this section must be sent in uppercase and are always terminated with
the ASCII carriage-return character, 0x0d (represented by the  symbol).
2. All responses are terminated with the ASCII carriage-return character, 0x0d.
3. All spaces shown in the commands are required. Lowercase letters are used as value
placement indicators, the required value or identifier is given in the Details panel for the
respective command.
4. The RS232 commands can be sent to either the SY-HDBT-70SP-T or SY-HDBT-70SP-R
without regard for the actual unit being controlled. Any command containing TX is
always routed to the SY-HDBT-70SP-T and all RX commands routed to SY-HDBT-70SP-R.
5. All RS232 communications are passed through regardless of baud rate or other settings.
This allows the use of third-party RS232 communication without having to set the
protocol specifics – Just pass-through.
SY-PCTools
SY-PCTools is a PC software package that allows the user to interface/control most of SY products,
all within one Tool. Please interface with RS232 (Tx, Rx) port of Slim70-Pro (transmitter or
receiver) via a com-port (or USB to RS232 dongle). The control panel provides a very simple and
easy interface for managing /monitoring the Slim70-Pro set. This is highly recommended for
installation as well as possible maintenance requirements.
All the following commands, except for the HELP command are included in the SY-PCTools
software, downloadable from the SY website.

4K Down-Scaling
Compatibility with 1080p display units is assured by down-scaling any 4K (24/25/30/50/60Hz)
signal to 1080p. All 1080p or less signals are simply passed through.
For 4K display requirements, 4K60 4:4:4 (or 4K50 4:4:4) input signals can be down-scaled to
4K50/60 4:2:0, ensuring the 10.2Gbps maximum output bandwidth is not exceeded (Max. 40m).
All lower bandwidth signals (< 10.2Gbps) such as 4K30 4:4:4, 1080p are just passed through.
There are three options available:
1080p: Down-Scale any 4K signal to 1080p
4K60-420: Convert 4K50/60 4:4:4 to 4K50/60 4:2:0 - (colour space conversion)
Auto: cat5e/6/6a cable and the display capabilities are analysed for optimal resolution /
colour space (4K 4:2:0 or 1080p) for 4K50/60 4:4:4 input.
Note: The frame rate is not altered – only the resolution or colour space is changed.
The following command selects the 4K handling mode:

2. When the device enters the Temperature Warning condition, the red PWR LED will
slow flash once every two seconds. When the device enters the power off condition
due to excessive overheating, the red PWR LED will fast flash three times a second.
3. An automatic GET TX/RX SAFE_TEMP_VALUE RS232 response is reported (sent), in
case of Temperature Warning / Power Off condition.
