A 50-Ohm bulkhead SMC jack is available for connecting an antenna to the

GPRS/CDMA module.

5. GPS System

A 12-channel GPS receiver (Trimble Lassen iQ) comes standard with the SI-VEU3.0. An

SMA female connector is provided for antenna connection to the GPS.

6. 802.11b WLAN

The SI-VEU3.0 offers IEEE 802.11b connectivity. The unit also supports IEEE 802.11e and

IEEE 802.11i with WMM Quality of Service enhancements and WPA Security

enhancements. This is achieved through the Philips BGW200 chip. There is an SMA jack

available for connecting to an external antenna. Alternatively, wireless LAN

connectivity could also be achieved through wireless Compact Flash card.

7. Power Switch

This is the main power switch for the unit. The Switch indicates “0” while OFF and “1”

while ON.

8. Power and Ignition Detect

The SI-VEU3.0 operates at 12/24V DC. The power connector also has an Ignition detect

line to automatically wake the SI-VEU3.0 from sleep mode. This feature is used to

conserve battery when vehicle is off. The Ignition detect line has internal protection

against over voltage. The pin-out of the connector, as viewed externally is shown in

Figure 2 and described in Table 1.

The mating connector is Molex Mini-Fit, Jr.™ P/N: 39 - 01 – 403x and crimp P/N: 44485

– 1211 with 18AWG wire.
