Communicating with Other Devices
The vehicle cradle is designed with a standard serial port and an
external USB bus so you can connect external devices such as a printer
or modem. Upon initial start-up, the serial port is the default for this
computer. To change SCU settings, see Section 5 “Customizing
Settings” in this manual, or contact your companies help desk for
assistance. The USB port is not supported under NT.
Important
•
A temperature of -20ºC to +60ºC (-4ºF to +140ºF) is
recommended when charging batteries with the vehicle cradle.
Batteries may not charge successfully outside this temperature
range.
•
If you charge your battery daily, rely on the gas gauge reading to
determine battery capacity. The gas gauge displayed by Battery
Status may show that the battery is full, but the external power
indicator light may still be blinking. This typically occurs if the
charge mode switched from Fast to Slow because the battery
became too hot. The charging process is trying to put a little
more capacity into the battery; however, external power can be
removed since the battery is virtually full.
•
If your battery is new or has not been used for several weeks,
rely on the indicator light to determine when the battery is fully
charged. The gas gauge is unreliable in these cases; it may read
100 percent, when the actual capacity is only 10 percent.
