Figure 19 Configuration Switch Settings for a HomeBase Network
When Switch 2 is in the ‘PROGRAM’ position, the baud rate can be changed using
the following procedure or by using the HomeBase Configuration Utility.
Enter or send the escape and command strings:
<ESC>HHPBn
n is the ASCII number corresponding to the baud rate shown in the table below. For
example, the string <ESC>HHPB6 (which consists of the escape string and the
command B6) would set the baud rate for the network to 19200. No response will be
transmitted back to the host after executing this function.

Device Selection
Use this command to enable the host device to select a specific Dolphin HomeBase in
the network for communication.
1. Enter or send the escape and command strings:
<ESC>HHPSn
where n is the unit ID of the Dolphin HomeBase being selected
2. The Dolphin HomeBase with the unit ID corresponding to the ID number in the
Device Selection command string will respond with:
<ACK>n
to indicate to the host that it is present. N is the unit ID.
NOTE
The baud rate is stored in
Non-Volatile Memory and is
retained even if the power is
removed from the network.
