The power supply and RS232 connectors are located on the bottom of the unit.

To run on vehicle power, you can use the 12 VDC cable. The appropriate cable comes with 
the kit you ordered. The 12 VDC cable can be used with a cigarette lighter outlet.

Verify that the power source is always within the specified range and observe correct 
input voltage polarity. An improper input voltage range or reverse polarity could damage 
the power conversion circuitry.

Use a standard serial cable to connect the unit to a host device via RS232; see
