DMD2050 Universal Satellite Modem

5.1 Compact Flash

The compact flash slot is located on the right side as viewed from the rear of the unit. A 128 Mbit
flash memory card stores all the modem M&C and operational data. It must be present when the
modem is operating.

5.2 Power Input Modules

5.2.1 AC Power Input Module

AC Input Module (Figure 5-1) is located on the left side of the unit. Power applied to the port with
the supplied power cable is 100 – 240 VAC, 50 – 60 Hz. Integrated into the Power Input Module
is the Power On/Off Rocker Switch. Power consumption for the unit is 1A. A chassis ground
connection (#10-32 threaded stud), is located to the lower right of the module.

5.2.2 DC Power Input/Switch

The Optional DC Power Input and Switch (Figure 5-1) is available for the DMD2050 products.
The unit may be powered from a 48V ± 5VDC source with a maximum unit power consumption of
3 A. Refer to Table 5-1 for pinouts.
