Bottom Panel
The power supply and RS-232 connectors are located on the bottom of the unit.
Power Supply Connector
Use this connector to attach an HHP power cable to the Dolphin 9500/9550 Mobile Base. The Mobile Base can be
powered by an external DC power source of between 11 VDC to 48 VDC.
To run on vehicle power, you can use the 12 VDC cable or 24 VDC cable option. The appropriate cable comes with the
kit you ordered. The 12 VDC cable can be used with a cigarette lighter outlet. The 24 VDC, pigtail cable can be used to
“hard-wire” into the vehicle power bus.
Verify that the power source is always within the specified range and observe correct input voltage polarity. An improper
input voltage range (above the 48 VDC maximum) or reverse polarity could damage the power conversion circuitry.
RS-232 Communications Port
Use a standard serial cable to connect the unit to a host device via RS-232; see Mobile Base Serial Connector on page
11-8.
