SY ELECTRONICS SLIM 70-PRO SY-HDBT-70SP-R (01) PDF Document

1. Connect a video source to the Transmitter (SY-HDBT-70SP-T) HDMI input connector and the remote display device to the SY ELECTRONICS SLIM 70-PRO SY-HDBT-70SP-R HDMI output connector.

2. Ensure the catx cable is wired correctly.

3. Plug the cat5e/6/6a cable into the RJ45 jacks of the Transmitter and Receiver units.

4. If needed, connect any optional inputs and outputs such as audio, IR or RS232.

5. Power up the extender by connecting the 48V DC power adaptor to either Transmitter or Receiver unit. Only one PSU is required due to the iPoC function.

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 long runs in close proximity to mains cables should be avoided. The RJ45 connector shielding ensures proper utilisation of full STP/FTP cat cables, such as cat-5e STP or cat-6a.

The iPoC function ensures safe powering of the remote unit. 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.

Both connectors must be wired identically according to the T568B standard. The RJ45 Plug Colour Code (T568B) from pin 1 to 8 is: White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown. Ensure the Cat6 cable uses 4 pairs of 23AWG solid copper wires.

There are three options available:

1. 1080p: Down-Scale any 4K signal to 1080p.

2. 4K60-420: Convert 4K50/60 4:4:4 signals to 4K50/60 4:2:0 (colour-space conversion).

3. Auto: Provides optimal resolution or colour-space option, based on cable length and display capability.

The IR IN and IR OUT ports on the rear of the units are used to send IR remote control data. The wiring connections for the 3.5mm jack terminal are as follows:

3.5mm Jack Terminal	IR Eye (Receiver)	IR Bud (Emitter)
Tip	5V	5V
Ring	IR Signal	Not applicable
Sleeve	Ground	IR Signal

The ASCII commands for the SY ELECTRONICS SLIM 70-PRO SY-HDBT-70SP-R use the following port settings: Baud Rate: 57600, Data Bits: 8, Parity: None, Stop Bits: 1. All commands must be sent in uppercase and are terminated with the ASCII carriage-return character (0x0d).

Diagnostic tools include:

Cable Length: Reports cat6 cable length between 20-70m.

Link Status: Indicates if the Transmitter and Receiver units are intercommunicating correctly.

Signal Status: Indicates video signal activity on HDMI input or output.

Signal Error: Indicative of cat6 signal line quality.

Input HDMI Signal details: Detailed information such as resolution, refresh rate, colour depth, HDR setting, compressed audio setting, audio rate, audio channels, HBR and HDCP.

Pulse HPD: Forces the HDP line low for 200ms.

Voltage Values: Reports power supply and iPoC power voltage levels.

Temperature Read: Reads temperatures closest to the main heat source.

The device is designed using the casing as a heatsink for power dissipation. This ensures chipsets run at lower temperatures. It is normal for these devices to run hot, especially the Receiver unit, so ensure adequate ventilation and avoid placing them close to other heat sources. The system also includes temperature control that allows the units to safely shut down in the event of an excessive temperature rise.
