G2100S-hx4700 |
G2100S Cradle kit for
iPAQ hx4700 or hx4705
This is a very nice cradle. It is small and simple and
lightweight. Includes an RJ (phone jack) connector for GPS
connection. Provides 5V power to the iPAQ. The included
cigarette lighter power cable provides 12 VDC power to the cradle and
the internal 12V to 5V converter provides power for the iPAQ.
Since most switching power converters are electrically noisy, I'm
assuming that the unit may interfere with nearby aircraft radios.
The optional Goddard Modification (see below) is highly recommended for
use in sailplanes.Included
The G2100S is designed as a "Car Kit". It ships with the items
listed below:
- 12V cigarette lighter power cable
(provides 12 VDC, There is a 12V to 5V power converter in the
cradle.)
- Locking Face Plate (slides onto back
of the cradle and has holes that can be used to mount any
RAM mounting or the
RAM-GN3-238 gooseneck adapter)
- 360 Degree Swivel Adapter
- Air Vent Pedestal
Compatibility
The G2100S cradle can be used with any RAM
mounting arm and with the Cumulus
RAM-GN3-238 gooseneck adapter and
GNeck2 gooseneck.
Comparison with RAM-HOL-CO5P Cradle
The Seidio G2100S is much more elegant than the
RAM-HOL-CO5P cradle. However,
the G2100S cradle relies on a friction fit to hold the iPAQ in the
cradle. It does not hold the iPAQ quite as securely as the
RAM-HOL-CO5P. It holds is
securely enough (in my opinion) for use in a sailplane, but not for use
in a 4x4 off-road vehicle or on a bicycle or motorcycle. Between
the 2 cradles, I would choose the Seidio G2100S for use in my sailplane.
If you are concerned that the iPAQ may slide out, I suggest using Velcro
on the cradle and iPAQ as shown in the photos below to secure it.
Suggested Velcro Modification
(Velcro not included)
I put one small piece of Velcro on the top of the cradle and another
small piece on the back of the iPAQ. I then used another piece of
Velcro to secure the iPAQ to the cradle. Click on the images below

Wiring Diagram
If you want to wire a GPS to the RJ connector on the cradle you will
need the wiring diagram below. You won't need this if you order
the Goddard Modification described below.
Note: Pin 4 is for 5V power output for powering the GPS.
Optional Goddard Modification - $79 (modification) + $49.95
(cradle) = 128.95
Highly recommended for use in sailplanes
Goddard has now made available a service for
modifying powered PDA cradles so that a single
power/data cable exits the back of the cradle and the noisy
internal power converter is removed. The Seidio G2100S cradles are
nice, but the standard connection for power and GPS data use 2 different
connectors. Also, the internal 12V to 5V power converter has
proven to be too electrically noisy for use in sailplanes because it
interferes with the aircraft radio. Since there is no connection
for 5V power on the cradle's connectors, the cradle must be modified for
use in a glider. The modified cradle setup makes for a very clean
installation. Since the internal power converter is removed, 5V
power must be provided to the cradle from a Cambridge
302, 302A,
LX1600,
LX7007, Goddard PS-5a or
SPS-1, or
Borgelt PDA-PS. To connect to any of those devices you will
want to order the DB-9m connector option. To connect to a
Cambridge CAA-127
57 mm adapter plate you will want to order one of the RJ connector
options. I will try to keep a few units with DB-9m connectors and
1m and 0.3 m cables in stock. Otherwise the lead-time for the
modification is 2 to 3 weeks.
