DM240XR High-Speed Digital Modulator

2.4.1 Initial Power-Up
Before initial power up of the DM240XR, 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 DM240XR 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 DM240XR can be accomplished from the front panel, Terminal
Port, Remote Port, or Ethernet Port.
