1. Install omni-directional antennas onto the M2T transmitter RF output port and
at the receiver end Down-Converter(s) RF input port. Note: Transmitters
should not be powered on without a load attached to the RF output
connector. The internal PA could be damaged.

connector. The internal PA could be damaged.
2. Attach an SDI video source to the M2T SDI BNC video input. A composite
signal can also be applied to the M2T I/O DB-44 connector using GMS break
out cable, however keep in mind that the video source must match the group
setting of the transmitter. Refer to the software section 6.0 on the selection of
the transmitter (M2T) video groups.

setting of the transmitter. Refer to the software section 6.0 on the selection of
the transmitter (M2T) video groups.
3. The MSR should be pre-configured from the factory (refer to the GMS web
site for the online manual). In short ensure the MSR is powered, has a cable
from the ASI out to the decoder ASI input, that each tuner has a RF cable
which runs to each block down converter (each tuner is provided power either
through the MSR or locally) and is set to the same RF frequency as the
transmitter.

4. Attach a video cable from the video out of the decoder to a video monitor.
Refer to the decoder’s operational manual for proper setup.
NOTE: Before providing power to the M2T in the following step ensure
to use a proper heat sink with adequate air flow or equivalent heat
sinking method.

5. Provide power to the M2T (+12 Volts) using GMS break out cable (780-
C0291) which connects to the I/O DB-44 pin connector. Power supply should
be able to source approximately 2 amps.

provided by the source should be displayed on the monitor. An optional
computer with the MSR control software installed can be used to monitor the
receive parameters such as BER, MER and Signal to Noise. This connection
can be through the USB or RS232 port.

The initial checkout described above is simply to check the basic video operation
of the M2T unit. For further details on monitoring and controlling the M2T using
GMS’ optional MS Windows-based M2T Configurator software program, see
Section 6.0.
