Model LDVDSV2

The B&B Electronics AutoTap™ OBDII Data Streamer Model LDVDSV2 connects your PC, driver terminal, Java-enabled
phone, or other on-board computing device to the OBDII diagnostic bus of light and medium duty vehicles. It enables the
retrieval of the most commonly used parameters of value in telematics and fleet management applications.

The LDVDSV2 provides a simple operational protocol to communicate to the OBDII bus. It provides a common interface and
deterministic response time for all vehicles. The complete Command and Response protocol is published on B&B’s website

www.rvdstreamer.com.

Environmental Testing

Temperature Test:

Ten (10) temperature cycles as follows with unit operating normally

1. Room (25ºC) to Tmin in 15 minutes.

2. Soak at Tmin 1 Hour with power removed from unit

3. Start unit at Tmin, confirm successful start by executing a command/response. Power-down unit. Maintain unit un­powered for one minute between power-ups.

4. Repeat Step 3 three times

5. Start unit at Tmin and ramp Tmin to Tmax in 30 minutes

6. Operate at Tmax for 1 hour

7. Ramp Tmax to Tmin in 15 minutes

8. Repeat steps 1 through 7 nine times for a total of 10 cycles:

a. 5 cycles at Vmin input
b. 5 cycles at Vmax input

Vibration Test:

IEC 60068-2-6
10 sweeps of 10 to 500 to 10Hz at rate 0.5 oct/min. each axis.
Level to be 10 to 36Hz, 0.06 in DA 36 to 500Hz, 4g’s
Unit must remain operational during and after the test.

Shock Test:

IEC 60068-2-27
18 to 50g’s, 11ms, ½ sine pulses, 3 each direction each axis
Unit must remain operational during and after the test.

Drop Test:

IEC 60068-2-32
10 Freefall drops from 1 meter onto concrete surface.
Drop 1 time one each face (6), 1 on a corner and the 3 edges of this corner.
