Base Station Specifications
Placing the Base Station
Connecting the Base Station directly to a USB port allows a maximum cable
length of 16.5'' (5 m). The Base Station is capable of communicating with the
vehicles in your fleet over a distance of at least 600' (200 m). line of sight,
without walls. See “Appendix: Advanced Connections” on page 8 for
information on advanced Base Station networks that allow for greater
distances between the computer and the Base Station.
Use the five LEDs on the Base Station to determine a location with good
signal strength between the Wireless On-Board Modules and the Base Station.
The Bottom LED displays green to indicate that the Base Station is on and
yellow to indicate it is communicating with the computer. The top four LEDs
indicate the current signal strength between the Base Station and the Wireless
On-Board Modules. Four LEDs indicate excellent signal strength. One or no
LEDs indicates poor signal strength.
If your location requires more than one Base Station for good coverage of your
fleet, repeat installation instructions 2-4 on the previous page for each
additional Base Station. The FMS system limit is 5 Base Stations.
