Memory

Apart from the 64KB cache, the SI-VEU3.0 has 32MB SDRAM and 8MB Page/Burst-

Mode Intel StrataFlash® for higher performance. In addition, a CF socket is provided for

additional memory. The micro controller has 128KB built-in Flash and 16KB RAM.

Operating System

The SI-VEU3.0 is built on the latest Microsoft Windows CE.NET operating system.

CE.NET version 5.0 provides enhanced real-time processing, greater interoperability and

faster performance.

Accelerometer

The SI-VEU3.0 comes with a three-axis accelerometer capable of handling up to ±6g. The

third axis eliminates any mounting limitations, which are common to 2-axis devices.

This feature can be used to detect a vehicle impact, useful for alerting a central office or

for accident reconstruction.

Real Time Clock

The SI-VEU3.0 features a battery powered Real Time Clock that comes standard.

GPRS/CDMA

The SI-VEU3.0 comes with a choice of either a GPRS or a CDMA cellular modem for

data communication. Two-way voice communication is available only with additional

equipment from Si Solutions.

The Quad-band GSM/GPRS Modem Module (Wavecom WISMO Quik Q2426) is

capable of operating at E-GSM/GPRS 900/1800 or 850/1900 bi-band. The Module has a

transmit power of 2W at EGSM 900/GSM 850 and 1W at 1800/1900MHz. The SIM card

is user-accessible through an external connector with a locking mechanism.

The 1xRTT CDMA module (Wavecom WISMO Q2438) is capable of supporting the

following four bands and modes: CDMA Band Class0 (Cellular 800MHz Band), CDMA

Band Class1 (PCS 1900 MHz Band), AMPS (Cellular 800MHz Band) and the Qualcomm

gpsOne (L1 1575.42MHz Band).
