Connecting to other devices using the serial clip
The optional serial clip 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 2008 series handheld.
You can use the serial clip to:
receive differential corrections from an external real-time correction source, 
such as a Trimble GeoBeacon receiver, or a DGPS radio (see 
Using real-time 
corrections from an external correction source, page 70
)
receive GPS data from a Trimble GPS Pathfinder series or GPS Pathfinder Pro 
series receiver
connect to other external devices, such as a laser rangefinder (see 
, and select COM1 
instead of a Bluetooth COM port)
connect to a computer to supply GPS data ( for example, when running the 
Trimble GPS Analyst extension for ESRI ArcGIS software on a laptop) (see 
)
supply external power from the external power kit or a vehicle’s battery 
(see
recharge the internal battery from an external power source (see
