7.11.3.1 Wiring Vehicle Power to the Cradle

The Powered Vehicle Cradle uses the vehicle power outlet or the vehicle fuse box to power from the vehicle

battery system. The Vehicle Power Outlet Adaptor (Model No. RV3050) is used for the vehicle power outlet;

the Power Extension cable (model number RV1205) is used for the vehicle fuse box.

Power cables are equipped with fuses and instructions are supplied with each cable. Use only a 4 A slow

blow Safety-approved fuse in the fuse assembly.

These cables should only supply operating power from the vehicle to the Powered Vehicle Cradle from

12VDC or 24VDC systems.

• The Powered Vehicle Cradle draws no more than 1.9 A @ 12 VDC or 0.95 A @ 24 VDC. Any additional

wiring, connectors or disconnects used should be rated for at least 3A. The Powered Vehicle Cradle

and peripherals can be used with both negative ground systems when using the Power Extension

cable. Peripheral wiring should be closely examined to avoid ground loops in positive ground systems.

• There is the option of connecting power to the cradle before or after the ‘key’ switch.

- It is preferable to wire after the key switch. In this configuration, when the key is turned ON, the

vehicle will power the cradle and docked EP10, charging the internal battery when needed. When the

vehicle ignition is OFF, the EP10 docked in the cradle will run on its internal battery.

- However, if the operator switches the key off repeatedly for long periods during a shift, it may make

more sense to wire the vehicle cradle before the switch. In this case, the EP10 will always operate

from vehicle power and that power will charge the battery when needed.

- Keep in mind that the EP10 will continue to operate with or without vehicle power as long as the

internal battery has sufficient charge.

7.11.4 USB and Serial Connections

The Powered Vehicle Cradle full configuration consists of one serial DE-9M port and one micro-USB port

located at the base of the cradle. These are COM and USB ports that allow serial and USB devices to com-

municate with the EP10. These ports include:

•One powered USB micro AB.

• One full Serial port.

Peripherals such as scanners, printers, GPS, etc., may be used with the EP10 and the cradle. Check with

Psion if there is any compatibility issue with the device you want to use with the EP10 and the cradle.

7.11.5 Inserting the EP10 in the Vehicle Cradle

The Powered Vehicle Cradle has a spring action that allows it to stretch up to accommodate the EP10 and

then snap in place to hold the hand-held securely. You do not need to remove the hand-strap to insert the

hand-held in the cradle. To insert the EP10 in the Powered Vehicle Cradle:

• Insert the top of the EP10 in the cradle, and push the unit upward while you align the bottom of the

EP10 with the base of the vehicle cradle.

• Release the EP10 to allow the cradle to firmly grip the hand-held in place.

• Push down on the top of the cradle to ensure that the EP10 docking port is firmly connected to the

Powered Vehicle Cradle.

Warning: A properly trained technician must perform the power connection using Power

Extension cable, model no. RV1205 (PN 1101033) and the RV1005. Improper con-

nection can damage the vehicle or the cradle.

This cable can be used to provide power to RV1005 from a fused circuit. The

vehicle cradle should be added to a fused circuit with a new maximum load capac-

ity of the original load plus the cradle load, which is 3 A.

Important: Depending on the configuration, the RV1005 Powered Vehicle Cradle has a maximum of

two connectors and one power connector.
