www.octagonsystems.com Page 6 of 25
The Fleet–CORE accepts a DC input voltage which can be powered from fixed supplies,
vehicle batteries or railway power systems. The internal power supply has a very robust
front end, exceeding the SAE J1113-11 and ISO 7637-2 specifications. It is also reverse
polarity protected. The input range is from 8 to 36 VDC.

Fleet–CORE major software features
Diagnostic software verifies system integrity automatically
The Fleet–CORE has built-in diagnostic software that can be used to verify on-card I/O and
memory functions. On power-up, a series of tests is performed. If a problem occurs the failed
test can be identified by the flashing Status LED. The test is performed automatically every
time the system is reset or powered up. Memory verification does not require software, test
equipment, monitor, keyboard, disks, or test fixtures.
AMIBIOS BIOS
The Fleet–CORE has an AMIBIOS BIOS. Refer to the Fleet–CORE Programmer’s Guide for
Setup information.
Boot sequence
The Fleet–CORE can be configured to boot from CompactFlash, a SATA hard disk, or a CD–
ROM; or from a USB device such as a floppy drive, hard drive, flash device, or a CD–ROM. A
USB boot allows software installation without opening the case.
Configuring and Ordering Your System
Hard Drive Options
The Fleet–CORE comes standard with a 4 GByte Compact Flash device. The Fleet–CORE
also supports SATA and USB drives.
The internal Compact Flash socket looks like a hard drive to the system. This socket accepts
Type I or Type II Compact Flash devices. The Compact Flash feature is CF 3.0 compliant,
DMA capable, and supports true IDE mode. Octagon Systems only recommends industrial
grade, error-correcting Compact Flash of the quality included with the system.
Expansion Options
The Fleet–CORE can be used in a stand-alone mode or expanded through the Mini PCI, Mini
PCI Express and PC/104-Plus interfaces. Up to two PC/104-Plus cards can be added. Nine
User Lines are available on the Option connector, as well as three SMA-F antenna
connectors.
Operating Systems
Octagon Systems can preinstall some operating systems, including drivers for the standard
features such as digital I/O and COM ports. Octagon Systems has drivers for Windows
XP/XPe and Linux for the standard Fleet–CORE features, as well as for Octagon System
expansion cards.

Installation
Recommended Installation Practices
The Fleet–CORE is designed to operate in difficult environments. Proper installation
will help ensure product longevity and adherence to the product standards.
1. The back endplate of the Fleet–CORE can be removed for access to the COM4
termination switches, PS/2 keyboard mouse, SIM socket for Mini PCI Express
SIM cards and Reset. The bolts require a 4 mm hex wrench.
CAUTION! When replacing the back cover ensure the threads on
the bolts are properly aligned before tightening. Do not over
tighten. Torque to 1.1 N-M (10 in-lbs.) Failure to follow these
precautions could strip the internal threads.
2. There are no internal repairable components. Field repair is not covered by
the Octagon warranty.
3. Do not over-tighten the antenna or GPS connectors.
4. The Fleet–CORE can be stand-alone mounted with six 4 mm hex bolts, or
attached to an optional mounting bracket which is then fastened to the
operating environment. The bolts must be 6.35 mm longer than the thickness
of the plate to which you are mounting to ensure a sufficient number of
threads are engaged. The threaded cavity in the case is 7.93 mm deep.
5. The power supply cable should be as large a gauge and as short in length as
practicable.
6. The Fleet–CORE is protected against transient voltages common in outdoor
applications. It is required that an external in-line fuse be used if a remote
power supply is used. This will prevent catastrophic damage from power
supply reversal and sustained over-voltage. A fast-acting fuse at 10A must be
used.
7. Proper ESD precautions and method must be followed when installing,
servicing, or otherwise handling the Fleet–CORE.
8. The USB signals are USB 2.0 with a maximum cable length of 5M. Cables
with built-in repeaters are available commercially if a longer cable length is
required.
9. The Fleet–CORE is rated for 12V to 24V nominal, but accepts 8V to 36V.
www.octagonsystems.com Page 8 of 25
10. The Fleet–CORE contains several switching regulators with an inrush
requirement of 15A. The external supply must be capable of supplying this
inrush current so as to not “starve” the startup of the internal supplies. If the
power supply is mounted remotely to the Fleet–CORE, the wiring gauge must
be adjusted to prevent excessive drop during startup.

The Fleet–CORE can be stand-alone mounted with six 4 mm hex bolts, or attached to an
optional mounting bracket which is then fastened to the operating environment. The bolts
must be 6.35 mm longer than the thickness of the plate to which you are mounting to ensure
a sufficient number of threads are engaged. The threaded cavity in the case is 7.93 mm deep.
Use washers to ensure the threads available are at least 6.35 mm but less than 7.93 mm.
Torque to 1.5 N/meter (14 in/lb). To ensure adequate air flow for convection cooling, mount
the Fleet–CORE so that there is a 100 mm (~4 in.) air space around the top, sides and front
of the enclosure.

www.octagonsystems.com Page 11 of 25
The Fleet–CORE provides one 10/100Base-T Ethernet port (top, LAN0) and one
10/100/1000Base-T Ethernet port (bottom, LAN1). Both ports support the IEEE 802.3
Ethernet standard. The Ethernet ports use PCI interrupts as assigned by the operating
system. Note that you must have two Ethernet drivers installed to be able to use both
Ethernet ports. The Ethernet drivers are on the Octagon Systems web site.

GPS
The front panel contains a SMA-F GPS connector. GPS receiver is a standard feature of the
Fleet-CORE system. The GPS is connected to the CPU through an internal USB interface.
The receiver supports industry standard NMEA messages, as well as the UBX packet
protocol. The protocol specifications are available from the Octagon Systems website.
