With the Dolphin 7200 Compact HomeBase, connect each device to the RS-232
Communications Port on the back of the HomeBase. The Compact HomeBase
cannot be networked.
Connect the power supply to the Compact HomeBase. Plug the AC transformer into
the Dolphin HomeBase 12 Volt DC power supply connector. The AC wall
transformer provided can power only one Dolphin Compact HomeBase.
Hand Held Products recommends that you leave the Dolphin Compact HomeBase
connected to its power source at all times, so that it is always ready to use.
