Hand Held Products 7900 Series 用户手册

The terminal requires 9.5 Volts DC input for communications and battery charging; the Hand Held Products power cable contains 
a power adapter that converts the power source voltage accordingly. Only the power adapter cable from Hand Held Products 
converts the voltage appropriately.

We recommend that you leave the Dolphin HomeBase connected to its power source at all times, so that it is always ready to use.

1. Connect the power cable to the DC jack on the rear panel of the HomeBase. 

2. Connect the power cable to the power adapter.

3. Plug the power adapter cable into the power source.

4. The Dolphin HomeBase is now powered. 

The following diagram displays the pin diagram of the serial connector of the HomeBase. 

Note: Signals referenced are for a DTE device. The HomeBase is at a right-angle to the printed circuit board (PCB). The ninth 

pin has a ring indicator (RI).
