Communicating with Other Devices
The vehicle cradle is designed with a standard serial port so you can
connect external devices such as a printer or modem. Specify COM2
when you select the communications port in your application. Connect
the external device to the serial port on the back of the cradle, and then
place the mobile computer onto the vehicle cradle. You can install or
remove the computer from the vehicle cradle without connecting or
disconnecting a printer or modem cable from the computer.
External Antennas
An external RF antenna also can be connected to the cradle using the
TNC RF connector on the back. FCC regulations require that users of
vehicle-mounted antennas must use only antennas authorized for use
with the mobile computer in order to meet FCC RF exposure limits.
Please contact your organizations’s help desk for a list of approved
vehicle-mounted antennas. For mounting installation and/or mounting
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, but the actual capacity is only 10 percent.
