Hardware overview
The D400 is (see Figure 2) built on a flexible, high-performance, expandable platform
powered by a 1.6 GHz processor. It is distinguished by the noticeable lack of a hard drive
and fan, employing instead the rugged and reliable CompactFlash mass storage and
engineered heat sink and ventilation.

(I/0) adapter cards:
• Serial (up to 8 configurable 2-port adapter cards): RS-232, RS-485, Fiber Optic (Glass or
Plastic)
