Hand Held Products Dolphin 7200 manual Communicating with the Dolphin Terminal

Page 61

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.

Baud Rate per Value of n

ASCII Value of “n”	Selected Baud Rate		ASCII Value of “n”	Selected Baud Rate


0	38400		6	19200

1	38400		7	38400

2	1200		8	57600

3	2400		9	115200

5	9600

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>HHP >100ms< 1s Sn

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.

When data transfer begins, the COMM LED on the Dolphin HomeBase will blink red and green. A unit remains selected until another unit in the network is selected. For example, the string <ESC>HHPS3 would select the unit with ID number 3 for communications. That unit would then send back an <ACK>3.

A selected unit in the Dolphin HomeBase network will assert the DSR signal of the HomeBase when a Dolphin terminal is present. The DSR signal can be used by the host application to determine if a Dolphin terminal is present and selected.

Communicating with the Dolphin Terminal

To communicate with the Dolphin and any other devices connected to the HomeBase:

1.Insert the Dolphin into the terminal well of the HomeBase. If the Dolphin is in sleep mode, it will awaken into active state.

2.The CHARGING MAINBATT LED on the HomeBase will turn on.

If the Dolphin does not turn on, or the LED does not light up, make sure that it is properly seated in the terminal well and that the power supply is properly connected to the HomeBase and plugged into a functioning AC outlet.
