1. Install Omni-directional antennas onto the M2TE 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.
2. Attach an SDI video source to the M2TE’s SDI 1.0/2.3 video input #1. A composite signal can
also be applied to the M2TE’s I/O – Control VHDCI-68 connector using Cobham break out cable,
3. The MSR should be pre-configured from the factory (refer to the Cobham 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 M2TE 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 M2TE (+12 Volts) using Cobham break out cable which connects to the I/O
– Control VHDCI-68 connector. Power supply should be able to source approximately 2 amps.
6. Turn on the video source and video monitor equipment.
7. Insure that the M2TE is set to Set-up Config Group #1. Refer to Section 6 for full Local Control
Panel operating instructions.
8. After approximately 30 seconds the link should be established and video 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 M2TE unit. For
further details on monitoring and controlling the M2TE using the M2TE’s WEB-based control and status
indicator, see section 7.
