The Service Tracker (ST-550) is a radio device that compiles and stores work/ idle, 
run and maintenance logs; connectivity is accomplished in RS232 and USB format 
via a secure radio link. The ST-550 does not support IrDA communication.  
In the operation mode, an ST-550 mounted on the dash board or on the top of the 
vehicle, has been logging in CMH (Cumulative Machine Hours), and compiling 
maintenance service times on the vehicle. Each maintenance procedure is assigned a 
Service Tracker number (up to seven different procedures can be tracked). The 
maintenance issues are displayed as service alerts. Each service alert has a designated 
identifier number (one through seven) that display on the “window eye” of the ST-
550. The number indicates that a particular maintenance procedure should be 
completed. When the service alert is satisfied the counter is reset with any supporting 
PDA (Personal Data Assistant).  
Retrieving the ST-550 data, such as the profile, service alerts, work/ idle/ run/ 
count/duration logs is accomplished with a supporting PDA, or by using the OEM 
Data Delivery manufactured mobile CPU called GoPOD. The GoPOD is configured 
with 512 MB Memory, 1 GB CF, Windows XP Embedded for ease of use. The 
housing is designed to be installed on a lube or fuel truck, low boy truck, mechanics’ 
truck or supervisor’s vehicle. The GoPOD is equipped with a GPS antenna, and a 
radio antenna. Information is collected passively, from the ST-550 and “hands-free”. 
GPS coordinates are automatically stamped into the record as hourly data is collected. 
Information is collected via drive-by, within a range of 300 ft. line of site, and 
transmitted via secure radio link.
