Review
by Dave Burrows
Introduction
The Leadtek 9532 supersedes the original Leadtek
9531. The 9532 has a nice bright new design, rather than the old boxy gray
style, the new Leadtek has a radical round design with a light blue/cyan colour
to the receiver. Leadtek is a good name behind GPS Receivers, and one that
both TomTom and PowerLOC have partnered with to bundle the receiver with their
latest products.

Connecting the Leadtek
The Leadtek 9532 plugs into the bottom Sync Port
of the Pocket PC. This is the same interface that the Pocket PC cradle
uses which is designated as COM1. This does mean that you do have to make
sure that any external keyboard drivers that use this same sync port, or any
third party accessory drivers will have to be disabled to use the Leadtek, but
this is the same with all GPS receivers that use the bottom Sync Port.
The Leadtek 9532 is both small
and light weight and also very portable. This
useful antenna complies with the NMEA-0183 data message standard and SiRF II
binary data protocol and can be configured to work with a variety of PC's, Pocket PC, and Palm devices.

So what does the Leadtek 9532 look
like ?
The Leadtek has a new bright design, it
doesn't look like most GPS Mouse Receivers which are gray ans square,
Leadtek have added colour to this, colour coded the RJ11 plug, and
even included a light to tell you if the receiver has acquired a 3D
Lock!
The cable that comes out of the GPS receiver has a suction cup moulded
around the cable. Although the base of the receiver is both
magnetic and has a rubbery felt to stop the receiver slipping around
the dashboard, the suction cup can help by suctioning the cable to the
windscreen to hold the receiver firmly in place.

Cable Sets
The end of the GPS receiver cable
terminates in an RJ11 plug, which then plugs into an RJ11 socket.
From this point on is considered a cable set (as seen in the following
photo).
The RJ11 plug, plugs into the RJ11
socket which is on the right of the dual cable box. This then
splits into two cables. One goes straight to the accessory
socket plug which gives you the power to the receiver, and the other
cable then goes straight to the Pocket PC.
The reason why the cable set has been
designed this way is not only does it give you power to the GPS
receiver, but it charges the Pocket PC at the same time giving you the
best of both worlds.
