INSTALLATION AND OPERATION SET-UP
The DMAU is easy to operate and use, requiring no special cabling since the main
input/output and + 26 VDC @ 15 A power connections are all blind mated into a
backplane. An inrush limiting circuit on the power supply section even allows for
‘hot’ insertion into the backplane. Transmission of RF power can be turned off
with a mechanical switch located on the front panel to allow for manual override
of software settings. Finally, an RS232 serial port on the front face-plate allows
for local communications to the amplifier microprocessor to enable field
diagnostics.
Upon initial power-up or reset, the tri-color unit status LED on the front panel of
the DMAU will be red. Normal operation, with RF enabled, will be indicated by
“flashing” green. Three states of alarm are also indicated by the LED. Red for
“critical,” Amber for “major,” and green for “minor” alarms.
