M-PC2

With thousands of systems installed, Microbus is established in the supply of PCs for the mobile environment.

The fastest M-PC system available, M-PC2, is based on the Centrino Pentium M processor technology.

With a mass of interfaces, the M-PC2 offers high performance and low power consumption.

High connectivity and feature rich design allow M-PC2 systems to support future expansion requirements.

The M-PC2 In-vehicle PC offers users further flexibility for their various mobile data projects whilst maintaining the design basics Microbus feels are fundamentally crucial for a PC to continue to operate effectively within a harsh mobile environment.

M-PC2M-PC2 Specsheet
The M-PC2 Windows 2000/XP system offers the range of interfaces to enable the use of many types of peripherals such as fingerprint readers, rugged printers, rugged keyboards, camera input and vehicle tracking systems. Externally the M-PC range is the same, internally the processors are different. The M-PC2 comes with either the 1.8GHz Pentium M Dothan or the 1.3GHz Pentium M Celeron along with a choice of memory from 128MB to 2GB thus offering users higher performance whilst maintaining low power usage.
The M-PC2 will support GPS for navigation, GPRS, Mini PCI, optional flash disk, Ethernet, video inputs, and disk heater. The full list of features and build options are shown below:

Ethernet 10/100Mbs with RJ45 twisted pair connector.
Hard Drive IDE: 80G or 40G Enhanced Secure Disk
Flash Disk Option 32MB to 20GB non-volatile IDE flash disk built in to the main unit.
Disk Heater The heater switches on when the disk temperature falls below 7°C, and switches off when it rises to 8°C. If the external voltage (usually from the vehicle battery) is below the system-defined Battery Low level (which is between 9.6 and 10.6V), the heater cannot be turned on. Users cannot enable or disable the disk heater if fitted.
Sound AC/97 Sound Blaster®-compatible sound system with a 1W speaker amplifier and audio jacks for: stereo line input and output, stereo speaker output, and mono microphone input. Sound output levels: Line output is 1V maximum root mean square into 10K Ohm minimum. Speaker output is 340mW maximum per channel into 8 Ohms.
Digital I/O (DIDO) 8 input and 8 output channels, optically isolated to protect the main unit. Optical isolators: Hewlett Packard HCPL-0701 devices or equivalent.The outputs are open collector transistors in two banks of four channels, numbered 0-3 and 4-7. Each bank has its own set of power and ground pins to power the optically isolated output stages. The maximum voltage on the power pin is 18V referenced to ground. The input signals are a differential pair with a 1K Ohm series resistor. The LED needs more than 0.5mA passing through it to turn it on.
Analogue I/O Four analogue input channels.
Parallel Port One standard 8-bit parallel port. Enhanced Parallel Port (EPP) or Enhanced Capability Port (ECP).
Serial Ports

There are up to 8 serial ports.
Two external RS232 serial ports with modem control lines.
Two optional external RS232 serial ports with transmit and receive data only. Four internal serial ports, one for touch screen, one for optional GPS and two for optional GPRS/GSM modem modules.

ESD protection:
Human body model: +/-15KV
IEC 1000-4-2 contact discharge: +/-8KV
IEC 1000-4-2 air-gap discharge: +/-15KV
A human body model specifies 5.33A at 8KV and 10A at 15KV.
IEC 1000-4-2 specifies 30A at 8KV and 56.25A at 15KV.

Keyboard & Mouse

PS/2 input provided by rugged combined D9 connector. Optional 5m cable and mouse/keyboard splitter available.

ESD protection:
Keyboard and mouse ports have 300W 5V transient suppressors.

GPS Module 12 Channel GPS receiver module mounted in the main unit and connecting to an external active (3.3V) GPS aerial. This option uses one of the serial ports (COM4). Antenna gain 12-18dB, max 23dB.The module is based on the SirfstarII low power chipset. The factory default configuration for this module is NMEA-0183 running at 4800 baud.

Backup Battery A backup service battery option stops the computer losing power immediately if the vehicle battery fails. The computer monitors the primary power source (usually the vehicle battery). If primary power is lost or interrupted, the computer switches to the backup service battery. The computer can then run on the backup until primary power is restored or the backup is exhausted. When it switches over, the computer can:- display a message, or sound a warning and shut Windows down in an orderly way.The computer controls charging of the backup battery.
Cage option A perforated metal cage protects the system unit from damage from other objects in the boot/vehicle. The cage also ensures that the shock mounts can work unhindered.
Operating Systems Microsoft Windows 2000 or Microsoft Windows XP. Also available with no operating system installed.
Relay Box Option Provides connection to the vehicle’s controls. For example, the relay box can be used to control a lightbar, or power to other equipment e.g. radios.
