MOBL-D2 Functional Overview
Description
The Octagon MOBL-D2 is a 32-bit X86-class computer in a ruggedized enclosure. The
connectors and interfaces are located on an external panel for easy access.
The MOBL-D2 provides the following external interfaces: GPS, Wireless LAN (optional),
Wireless WAN (optional), and Bluetooth; each with front panel antenna connections. A
rugged Display connection is provided with audio output and a USB connection for devices
such as touch-screen controllers. Similar rugged connectors are also provided for
Communications (Serial & USB), Ethernet, and Digital I/O & CAN Bus as well as external
power. External power can range from 9 VDC to 36 VDC.
Internally the MOBL-D2 has a Compact Flash socket, a PCI-104interface, a Mini PCI socket
(Wireless LAN), and a Mini PCI Express socket (Wireless WAN). The MOBL-D2 can be used
in a stand-alone mode or expanded through the PCI-104, Mini PCI, or Mini PCI Express
interfaces.
MOBL-D2 major hardware features
The Vortex86MX processor has a clock speed of 800 MHz, integral graphics and memory
controller supplied with 1 GB of DDR2 SDRAM soldered to the CPU board.
An optional Compact Flash drive if ordered with the system is installed for fixed disk
storage.
A Fifty Channel GPS receiver offers location and timing information. The receiver supports
3.3V powered as well as passive antennas.
A Bluetooth interface is standard on the MOBL-D2, and is provided with an external
antenna connected to the front panel.
A rear panel USB port with tethered cover is provided for maintenance, diagnostics, updates,
or other temporary use without the need to disconnect front-panel dedicated cables to access
a USB port.
The case of the MOBL-D2 is integrally coupled to the major heat producing components,
which significantly reduces internal heating. No cooling fan is required.
Internal Functional Expansion
The PCI-104interface accepts industry-standard PCI-104boards. PCI-104expansion boards
are available from several manufacturers. The CPU card also incorporates a Mini PCI and a
Mini PCI Express slot for radios or other communication devices
. The Mini PCI Express slot
supports only USB interface devices such as Wireless WAN cards, no PCI Express bus is
presented to the socket.
Robust Internal Power Supply
The MOBL-D2 accepts a DC input voltage which can be powered from fixed supplies, vehicle
batteries or train 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 9 to 36 VDC.
