4.3.1 Power Supply The M452 requires a +15 VDC power source capable of supplying 1.0 A.
DC power can be connected through the male DB-15 connector or through
the coaxial power jack. The coaxial power jack is configured so that the
ground connection is on the outside (shield) and the +15V connection is on
the center pin.
If power is to be supplied through the DB-15 connector, the positive
terminal of the power supply should be connected to pins 4 and 5 on the
15-pin connector and the common terminal should be connected to pins 3
and 15.
If the optional AC Power Adapter is used to provide power, it should be
connected to the coaxial power connector adjacent to the DB-15 connector
on the top of the M452. Use only the approved AC Power Adapter
provided by Teledyne API.
