The following table outlines the configuration switch settings:

Switch

Setting

Function

 

 

 

 

 

 

1

SINGLE (UP)

Single HomeBase only

 

 

 

2

FIXED BPS (DOWN)

Baud rate fixed at 9600

 

 

 

2

PROGRAM (UP)

Baud rate can be programmed

 

 

 

To ensure communications, leave Switch 2 in the FIXED BPS position and configure your communications software for 9600 baud.

When Switch 2 is in the PROGRAM position, the baud rate can be changed by entering or sending the escape and command strings:

<ESC>HHP >100ms< 1s Bn

where n is the ASCII number corresponding to the baud rate shown in the table below.

9

5

9600

 

 

 

 

 

 

 

 

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.

Note: You can also the HomeBase Configuration Utility program to alter the baud rate.

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.

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:
