RF Sample: Output Sample from Combiner thru Control
Board. In a CU1000, the sample level is approximately
70dB down from the output power level of the Drawer.
50Ω
The RF ON Channel output of the CU10 thru CU200 systems and the driver Drawers is at J9
the 50Ω “N” connector RF output jack located on the rear panel. In CU10 thru CU200
systems, the output of the Drawer at J9 connects to the analog filter and then to the antenna
for your system. In CU500 and higher power systems, the output of the driver Drawer at J9
is connected to J1 the 50 Ohm “N” connector RF input jack located on the rear panel of the
500 Watt digital/1000 Watt analog amplifier Drawer or to a splitter in multiple amplifier
systems. Check that the system power metering interface cable is connected from J11 the 9
position “D” connector located on the rear panel of the driver Drawer to J4 the 9 position “D”
connector located on the rear panel of the 500 Watt/1000 Watt amplifier Drawer. This cable
provides the control, status and operating parameters of the amplifier Drawer to the driver
Drawer. The RF ON Channel output of the amplifier Drawer is at J2 the 50Ω “7/16” (1.1cm)
Din connector RF output jack located on the rear panel that connects directly to the low pass
filter, the mask filter and then to the antenna for your system in single amplifier systems or
to a combiner and then the low pass filter, the mask filter and finally to the antenna in
multiple amplifier systems.
Maintenance
Innovator CXB Series Transmitters are designed with components that require little or no
periodic maintenance except for the routine cleaning of the fans and the front panels of the
modules and the periodic check of general tightness of hardware.
It is recommended that periodically, the time interval depends on the amount of movement the
cabinet receives, all mounting hardware, holding drawer slides, shelving and mounting plates
inside the cabinet are checked for tightness. All screws and bolts that are accessible should be
tightened initially when the transmitter is received and periodically thereafter if the transmitter
is moved by vehicle. All coaxial connectors, hard-line connections and hardware holding
combiners, splitters, or any other mounted items should be checked and tightened. The
amount of time between cleanings of the drawers and cabinets depends on the conditions
within the transmitter room. While the electronics have been designed to function even if
covered with dust, a heavy buildup of dust, dirt, or insects will affect the cooling of the
components. This could lead to a thermal shutdown or the premature failure of the affected
drawer. When the front panels of the drawers become dust covered, the drawer should be
pulled out and any accumulated foreign material should be removed.
NOTE:
To remove the
CXB series transmitter from the cabinet, the input and output cables must be removed from the
rear of the transmitter before the drawer can be pulled out completely from the cabinet.
A vacuum cleaner, utilizing a small, wand-type attachment, is an excellent way to suction out
any dirt from the drawer and cabinet. Alcohol and other cleaning agents should not be used
unless you are certain that the solvents will not damage components or the silk-screened
markings on the drawers and boards. Water-based cleaners can be used, but do not saturate
the components. The fans and heatsinks should be cleaned of all dust or dirt to permit the free
flow of air for cooling purposes. It is recommended that the operating parameters of the
transmitter be recorded from the LEDs and the LCD system metering on the front panel of the
drawer at least once a month to be used for comparison purposes in case of a failure. It is
suggested that this data be retained in a rugged folder or envelope and stored near the
transmitter.
