the IF to the RF operating band required, and amplifies the RF
output, as required.
All installations will include an antenna, either directional,
omnidirectional, or both. An MRC RF switch can be mounted on
the antenna mast to select the antenna required.
When using the mast-mounted antenna(s), a Nycoil conduit
sheath covers the wiring harness between the IDU and the ODU.
The wiring harness carries the DC power, 70 MHz IF, and
antenna band and polarization switching control. Additional
wiring is contained in the Nycoil conduit sheath for controlling the
antenna pan and tilt mechanism and for implementing additional
functions such as off-air monitors, mast lights, etc.
2.4 IDU Operating Controls
All controls are located on the front panel of the MTX5000 IDU.
There are no controls on the ODU.
All transmitter functions are controlled using the color LCD
display panel touch screen and/or function keys, as shown in
Figure 2-5 on page 2-5.
The color LCD display panel with touch screen and function keys
are used to select control and diagnostic menu screens for both
the IDU and the ODU. Option buttons displayed on the color
LCD display panel are used to control Preset selection, RF band
selection, channel selection, offset selection, antenna selection,
antenna polarization, transmitter operation (on or off), power
(low or high), and to monitor the status of the IDU and ODU.
The option buttons displayed on the color LCD display panel
may be selected using either the color LCD display panel touch
screen or the function keys.
