sy.uk 2V1.1
The MTF21 is a 2-input to 1 output Multi-Format Switcher HDBaseT Transmitter. The HDBaseT
output can broadcast up to 70m @ 1080p or 40m @ 4K 30Hz using cat6a cable.
It provides the following features:
1 HDMI input
1 VGA input
1 HDBaseT output
1 x RS232-CTL – For control
1 x RS232 port for HDBT data pass through
Bi-directional IR input/output
External contact closure / pushbutton interface
EDID Management
The two inputs can be selected using the front panel button, RS232 commands (RS232-CTL) or
external contact closure / push-buttons.

Using the MFT21
1. Connect the video inputs.
2. Connect the HDBT output to an SY-HDBT-SLIM-70SR receiver.
3. Power up the MFT21.
4. Press the SEELCT button to select an input to display.
5. To use Auto input detection, press and hold either the SELECT until the AUTO LED is
lit (~ 3S). Auto Input detection is cancelled when the SELECT button is pressed.
6. An external pushbutton interface to the INPUT SELECT connector may also be used to
select either of the two inputs.
Cascade Mode
Cascade mode can be enabled/disabled via RS232 commands (SET CAS EN, SET CAS
DIS), using the RS232-CTL port. This may speed up the overall system switching speed when
several devices are cascaded together, such as MFT21 to MSUHD88 to Apollo 4K to…
De-embedded Audio output
The Remote HDBaseT output is de-embedded and presented on the phoenix L/R Stereo
output. Only PCM stereo audio streams are extracted in this way.

RS232-CTL Commands
All commands are sent at 57600 baud, 8 data bits, no parity and one stop bit.
Commands are not case sensitive, but must always be followed by a carriage-return (0x0d).
All responses are in uppercase and provide an acknowledgement of the command or reply
with the requested data, and are terminated with a carriage-return & line-feed (0x0d 0x0a).

Using an External Keypad
The MFT21 has an interface for a simple external keypad for controlling the MFT21. The
external keypad consists of a normally open momentary push button and an LED for each input
as shown in the following schematic:

System Diagram
RJ45 Wiring
Both connectors must be wired identically, to T568B standard.
Note: You may use cat5e, cat6 UTP (cat6 preferred) in conjunction with the HDBaseT output;
however for best performance use cat6a or cat7 (particularly in electrically noisy environments).
The maximum distances & transmission performance for HDMI and HDBT may be compromised
by cable quality, patch panels, poor termination, wall plates, cable kinks and electrical
interferences. Generally ensure the cat cable is solid copper core of 23AWG (avoid CCA type), in
one straight run (avoid/minimise patches) and avoid close proximity to any noisy electrical
sources.
