Thank you for purchasing the MFS31-H (Omega 3) Multi-format Switcher.
This product is designed with professional AV installers in mind. The many extensive features
assist with system integration, validation and maintenance. Please carefully read this manual
prior to installation and keep for future reference. You can download further supporting
documentations from our web site (sy.co.uk)
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, lightening and static discharges.
Place the unit away from heat sources and allow adequate ventilation.
Shielded cables and in particular cat6, cat6a or cat7 are 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.

Using the MFS31-H
Connect the desired video sources (HDBaseT / HDMI) to MFS31-H input ports and connect the
display device to the HDMI output port. If needed, user can also connect any optional inputs
and outputs such as audio and RS232 port. Power up the device by connecting the 48V power
adaptor into MFS31-H 48V port.
NOTE: There is no need to power either of the HDBaseT transmitters alone, as MFS31-H support
iPoC function and can supply power to the remote transmitters (SY-HDBT-70-SP-T).

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.
Four options are available to allow handling of 4K HDMI signals:
Scale down to 1080p
Convert to 4K60-4:2:0
Auto: the system analyses the capabilities of the displayer to decide on the best option.
Off (default value): Pass input to output directly
The following command selects the4K60 handling mode:

Diagnostic Commands
Diagnostic tools such as Cable Length, Signal Error, Link/Signal Status, Test Pattern, Voltage
Values, are most useful during installation, using a PC (or laptop) together with an RS232
interface (or USB to RS232 dongle).
As well as these, other diagnostic commands such as, Input HDMI signal details, Pulse HPD,
Temperature values, can be invaluable for overall system fault finding and trouble shooting.

Note:
MFT31-H is designed to power the remote transmitters (iPoC capable) using the provided
48V PSU. It can also power non iPoC transmitters by using appropriate 24V PSU.
The MFT31-H can’t be powered by the remote transmitters.
RJ-45 Wiring
Both connectors must be wired identically.
HDBaseT signals will NOT pass through any Ethernet device. The HDBaseT ports on this device
must be connected directly to the HDBaseT port of the remote Transmitters.
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.
