Setting the Baud Rate

You may use the HomeBase Configuration utility program to select the baud rate. The program can also be used to change the host system's COM port and will run a diagnostic check for optimal communications. After changing the baud rate, you must power the HomeBase off and then on again. The program is one of the utility programs that come with the Dolphin OS and Development System. For more on HomeBase Configuration, see the chapter 9.

Modes of Operation

Through the Command Mode, the host application software provides command instructions for configuring a single Dolphin HomeBase or a network of HomeBases for communications. Once configured, the HomeBase(s) is in Transparent Mode and ready for communications.

Command Mode

You can configure a single Dolphin HomeBase or a whole network and select units for communications via the host application by entering the Command Mode. Data transmission is not possible while the Dolphin HomeBase network is in this mode.

Go into Command Mode by entering an escape sequence that informs the HomeBase network that it will be receiving commands from the host device or application.

The escape string is:

<ESC>HHP [>100ms<1s] Next Command

where ESC is an ASCII 27 character.

The escape string should be followed by a >100ms<1second period of line silence. When sending commands, the escape string must precede the command string. The HomeBase automatically exits Command Mode after receiving each command.

Programming commands used for configuring single Dolphin HomeBases include Version Number and Baud Rate Selection. You configure HomeBase networks using the Baud Rate Selection, Address Assignment and Device Selection programming commands.

Transparent Mode

When the Dolphin HomeBase is selected by the host application and ready for communications, it is in Transparent Mode. In this mode, the HomeBase facilitates point-to-point communication between the host device and the Dolphin terminal. Data sent through the RS-232 link is passed directly to and from the Dolphin terminal via the Infrared Link between the terminal and the HomeBase.

Configuring a Single Dolphin 7200 HomeBase

To prepare a single Dolphin HomeBase for communications, you must enter the Command Mode to configure the version number and select the baud rate.

Version Number

To retrieve the version number for the Dolphin HomeBase:

1. Enter or send the escape and command strings:

<ESC>HHP >100ms< 1s V

This command will return the version number but is not needed for communications.

Baud Rate Selection

The Dolphin HomeBase baud rate is set to 57600 at the factory. Use the configuration switches on the HomeBase's back panel to select the network and communications modes for your Dolphin.

Note: The configuration switches are checked at power up. Changes in the switch settings will not be recognized until power is turned off and then back on.

The baud rate is stored in Non-Volatile Memory and is retained even if the power is removed from the network.
