Initial Power-Up - Radyne ComStream DM240-DVB Installation And Operation Manual

DM240-DVB High-Speed Digital Modulator

2.4.1 Initial Power-Up

Before initial power up of the DM240, it is a good idea to disconnect the
transmit output from the operating ground station equipment. This is
especially true if the current modulator configuration settings are
unknown, where incorrect setting could disrupt existing communications
traffic. New units from the factory are normally shipped in a default
configuration which includes setting the transmit carrier off.
Turn the unit 'ON' by placing the rear panel switch (above the power entry connector) to the 'ON'
position. Upon initial and subsequent power-ups, the DM240 microprocessor will test itself and
several of its components before beginning its main Monitor/Control program. These power-up
diagnostics show no results if successful. If a failure is detected, the Fault LED is illuminated.
The initial field checkout of the DM240 can be accomplished from the front panel, Terminal Port,
Remote Port, or Ethernet Port.
