define the current draw values of the three MilSystem models, featuring either the

LittleBoard 735, COM 840 with EBX Baseboard, or the LittleBoard 800. The tables capture In-Rush, Idle,
and Burn-In-Test (BIT) currents at incremental input voltages from +14 to +32 VDC.

Table 1

lists the current draw values of the MilSystem with the LittleBoard 735.

Operating configurations:

In-rush operating configuration includes one LittleBoard 735, 2GB DDR2 RAM, AMI BIOS, AC/DC
external digital power supply, DC/DC internal power module, CRT monitor, HDD, keyboard and
mouse.

Idle operating configuration includes the same items as the In-rush configuration.

BIT (Burn-In-Test) operating configuration includes the same items as the Idle configuration as well as
four serial loop backs, one parallel port with loop back, two Ethernet connections, four external USB
flash drives, and one Compact Flash card.
