1.4.5 Construction
Enclosure
The MCE is robustly constructed and is housed in a shielded, self-ventilated
2U high enclosure. All external connections are via rear panel connectors.
The equipment is designed primarily for free-standing, but may be
mounted in a 19 inch rack, if required. It is lightweight and compact, and
suitable for both flyaway use (within an appropriate flight case) and truck
installation.
The equipment operates from a mains power supply, having a wide-
ranging power supply covering 100 – 120 Vac or 220 – 240 Vac at
50/60 Hz nominal. The equipment is intended to operate in ambient air
temperature conditions in the range 0°C to +40°C.
Boards/Modules in the MCE
The MCE contains a Motherboard

and a Video Compression Module which
are factory fitted in the two top tray positions provided by the enclosure
(see Table 1.6 and Figure 1.8). Video, Data and QPSK Modulator modules
are fitted in the three slots of tray three (see Table 1.7 and Figure 1.8).
