About the MilSystem
The MilSystem products are intended for users of turn-key embedded systems who require long life-cycle,
configuration controlled computers with MIL-STD-D38999 connectors. MilSystem models each feature one
of three Extreme Rugged™ computer boards: the LittleBoard 735 Single Board Computer (SBC), the
LittleBoard 800 SBC, or the COM 840 (Computer On Module) with the EBX baseboard. The
LittleBoard 735, LittleBoard 800, and the COM 840 are available with varieties of processors and memory.
An optional operating system (OS) can be pre-loaded onto an optional internal storage device (2 ½" hard
drive or Solid State Drive). Board Support Packages (BSPs) are provided on the optional Support Software
DVDs or QuickDrives™ to support additional OSs. Just use a USB memory device to load your application
software and you are ready to use your system.

This guide provides the most efficient way to set up your MilSystem with your desired OS. The instructions
provided in this guide include:
•Removing the MilSystem from the shipping container and inspecting the accessories
•Connecting peripherals to the MilSystem
•Military connector pin signals and descriptions
•Powering up the MilSystem
Information not provided in this User’s Guide includes:

Power Specifications
Tables 1 through 3 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.
Tabl e 1 lists the current draw values of the MilSystem with the LittleBoard 735.
