Creating a Dolphin 7200 HomeBase Network
This information applies only to the Dolphin 7200 HomeBase. The Dolphin 7200
Compact HomeBase is not networkable. Each HomeBase must have its own AC
power adapter connected to a standard AC electrical socket. The group can be placed
on a table or desk, or rail-mounted using the mounting holes on the two outside
Dolphin HomeBase units.
How to Daisy Chain the Dolphin HomeBases
To form a HomeBase network, daisy chain the HomeBases together using one of the
following methods:
•
Align adjacent units so that the MULTI-HOMEBASE PORT of one unit
will mate with the MAIN COMM PORT of the next unit until all
HomeBases in the network are connected.
OR
•
Use a RS-232 cable to connect the Multi-HomeBase Port on one terminal
to the MAIN COMM PORT on the next terminal. Repeat this step to
include each additional terminal in the chain. Connect the last terminal to
the host computer and leave the last MULTI-HOMEBASE PORT open
if it is not needed.
Programming Commands
To configure a Dolphin HomeBase network, these attributes must be programmed:
Address Assignment, Baud Rate Selection and Device Selection.
Address Assignment

HomeBase in your network. This must be done before a unit can be selected for
communications. To establish an Address Assignment:
