The Port Replicator
9.10.6.1 Wiring Vehicle Power To The Cradle
A 1.8 meter (6 foot) extension power cable (PN 13985) is supplied with your
powered vehicle cradle. This cable should be wired to a filtered, fused (maximum
10A) accessory supply on the vehicle. The power cradle draws no more than 8A
(less if the accessory supply is greater than 12V). Any additional wiring, connectors
or disconnects used should be rated for at least 10A.
The red lead of the power cable attaches to the positive vehicle supply. The black
lead connects to the negative supply
–this should be connected to a proper terminal
block and not to the vehicle body. The power cradle is fully isolated and can be used
with both negative and positive chassis vehicles.
You may have the option of connecting power before or after the ‘key’ switch. It is
preferable to wire the power cradle after the key switch
–that is, it cannot be turned
on without the key on. However, if the operator switches the key off repeatedly for
long periods during a shift, it may make more sense to wire the cradle before the
switch.
Keep in mind that the WORKABOUT PRO will continue to operate with or without
vehicle power as long as its battery has sufficient charge.
If an unfused power source must be used, a fuse assembly (PN 19440) must be
added to the extension power cable (the fuse and instructions are supplied with the
cable). Use only a 10A slow blow UL approved fuse in the fuse assembly.
9.10.7 The Port Replicator
The port replicator (Model# WA4005-G1) is an optional accessory that allows
tethered devices as well as mounted peripherals (e.g., bar code printers or weigh
scales) to be attached to the vehicle cradle. The replicator can be used with or
without the cradle power option.
