The Smart GPS antenna can communicate with the office computer using a serial 
connection from the DB9 connector on the receiver to a LEMO connector on the 
computer (see 

). You can also use the supplied DB9 to DB9 cable (P/N 18532 

or 59046 (RoHS compliant). Before you connect to the office computer, ensure that the 
receiver battery is fully charged.

Connecting the SPS881 Extreme Smart GPS antenna to a computer for serial 
data transfer

Data is stored in the internal flash memory. To transfer files between the receiver and 
your office computer, connect the receiver to the office computer and use the Data 
Transfer utility to transfer files.

When you use the Data Transfer utility to transfer data files from the receiver, the Data 
Transfer utility converts the raw receiver data (.T01) files you select into the Trimble 
DAT file format.

You can convert receiver data files by using a Windows Explorer extension which is 
installed on your computer when you install the Data Transfer utility. 

You can delete files stored in the receiver at any time. Do one of the following:

Press 

E 

 for 30 seconds after the receiver is turned on. (When you use this 

method, all data is deleted.)
