2.4.1 Initial Power-Up
Before initial power up of the MM200, it is a good idea to disconnect the
transmit output from the operating ground station equipment. This is
especially true if the current modem 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 applying power (DC versions), or placing the rear panel switch (above the
power entry connector) to the ‘ON’ position (AC versions). Upon initial and subsequent power-
ups, the MM200 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.
