User Manual Part 1

Routine Operation 3-7MTX5000 User and Technical Manual
If the RF IN connector option is a Type “N” or TNC, DC power to
the ODU is provided from the IDU via the ODU POWER
connector. If the RF IN connector is a Triax connector, DC
power and control is provided to the ODU from the IDU via the
RF IN connector.
POWER Connector The POWER connector receives DC
power from the IDU via the wiring harness between the IDU and
the ODU. The POWER connector is present on the ODU only if
your MTX5000 system contains either the TNC or Type “N” RF
IN connector options.
3.3 Preparing for Operation
The procedures required to use the color LCD display panel with
touch screen and function keys locally, in the normal user mode
of operation, are contained in the following paragraphs.
The color LCD display panel is used in conjunction with the color
LCD display panel touch screen or the function keys to make
selections displayed on the color LCD display panel.
The normal user mode is designed for you to recall existing
system Presets in order to properly transmit the video stream
back to the studio from a remote location.
Along with recalling a Preset that is appropriate for a given
broadcast situation, you can select between two antennas,
select between two ODUs (if your system contains two ODUs),
select an operating band, select a channel within the operating
band, select a channel offset, and select antenna polarization.
You can also select between high and low power operation of the
transmitter, you can turn the transmitter on and off, and you can
monitor any fault conditions that may exist within the MTX5000
IDU and/or ODU.
When power is applied to the MTX5000, it automatically enters
the local normal user operation mode. The MTX5000 will
remember the last settings that were in use, regardless if they
were a stored Preset or user-defined settings, and will return to
those settings. If the MTX5000 was transmitting when power
was removed, the IDU will not automatically return to the
transmit mode. If the MTX5000 was in the remote mode when
power was removed, the IDU will not return to the remote mode.
3.3.1 Mobile Installation
For mobile applications, the MTX5000 is typically mounted in a
bulkhead or compartment in a 19-inch (48.3 cm) rack and the
ODU is mounted on the vehicle antenna mast. The cabling is
permanently installed and power comes from the mobile AC
power source.
Each installation or deployment will have its own specific tasks
according to the application and the installed hardware options.
For additional information, refer to the “ Installation” section on
page 6-1.
3.3.2 Powering the MTX5000 System
CAUTION
Corruption of software contained in the
MTX5000 may occur if proper power down
or power up of the MTX5000 does not
occur.
The MTX5000 must be properly powered up and powered down
to prevent possible corruption of the software contained in the
radio. It will take approximately 60 seconds for the MTX5000 to
power up properly. As with a personal computer, it takes time for
the internal software to become initialized and the Main screen to
be displayed.
