Configuration switches Use these switches to select the network and communications
modes for your Dolphin. See Chapter 8 for more on the configuration switch settings.
Service Aux Batt switch Press and hold this button for four seconds to service the
battery in the auxiliary battery well. For maximum battery life, the battery should be
serviced, or calibrated once a month. The Charging AUX BATT LED is red while the
battery is discharging and changes to blinking red when the charging cycle begins. The
battery is ready to use when the light turns green.
Power supply connector Use this connector to attach a power supply to the
HomeBase. The power supply provides 12V DC input for communications and
battery charging.
Side Panels
There is a main communications port on one side and a multi-HomeBase-port on the
other side:
Main Communications Port Use a standard serial cable
to connect this port to a host RS-232 device if the
Dolphin HomeBase is the first unit of HomeBase
network. Otherwise, the main communications port
connects to another Dolphin HomeBase Multi-
HomeBase Port to form a daisy-chained network. See
pinout definitions in the section on Setting Up the Dolphin
HomeBase later in this
chapter.
Multi-HomeBase Port Use this port to form a Dolphin
HomeBase Network. This port mates with the next
HomeBase’s main communications port to form an
addressable network. Note: The Multi-HomeBase Port
cannot be used for communications to
standard serial devices.
