68 GeoExplorer 2005 Series Getting Started Guide
Using the Optional Serial Clip 15
The optional serial clip (P/N 53550-00) attaches to the
communication swipes on the back of the handheld. When the serial
clip is attached, it adds a serial port (COM1) to the GeoExplorer 2005
series handheld.
Note – The GeoExplorer 2005 series handheld is not compatible with the
serial clip supplied with previous versions of the handheld. You must use
the gray serial clip (P/N 53550-00) provided with the GeoExplorer 2005
series handheld.
You can use the serial clip to:
• supply external power from the external power kit or a vehicle’s
battery (see Using external power, page 36).
• recharge the internal battery from an external power source
(see Using external power, page 36).
• receive differential corrections from an external real-time
correction source, such as a Trimble GeoBeacon or
Beacon-on-a-Belt (BoB
™
) receiver, or a DGPS radio
• receive GPS data from a Trimble GPS Pathfinder series or GPS
Pathfinder Pro series receiver
• connect to an external modem or mobile phone for wireless
Internet access
• connect to other external devices, such as a laser rangefinder
• connect to a computer to supply GPS data ( for example, when
running the Trimble GPS Analyst extension for ESRI ArcGIS
software on a laptop)
Note – When connecting to an office computer using the serial clip, you
cannot use ActiveSync technology to establish the connection or
synchronize data. To use ActiveSync, you need to use a support module
USB or a Bluetooth connection (see ActiveSync Connections, page 15) .
