Figure 107: Example software connection for a DT80 on an Ethernet network (DeTransfer software shown)

Note: When creating a new connection the current version of DeTransfer defaults to Port 8. It must therefore be explicitly set to Port

7700.

If you now press Connect, you should be able to send commands to the DT80 and receive data, just as you would using

USB or RS232.

Multiple Connections

Up to three client computers (or three DeTransfer sessions on the one computer) can simultaneously connect to the

DT80 command interface using the TCP/IP network. This is in addition to a possible USB and/or RS232 connection.

At any one time, only one of these interfaces/sessions can be the active interface. The active interface is the one on

which the most recent DT80 command was sent.

Whenever the DT80 transmits something over the command interface (e.g. returned/unloaded data, prompt strings,

messages, etc.), it is send to the current active interface, plus

all connected TCP/IP sessions. This provides a way to

"broadcast" data to a number of different computers, each of which operates as a passive listener.

Disconnecting

It is important to note that all Ethernet sessions will be disconnected if the DT80:

• undergoes a hard reset (

HRESET, manual reset or power failure)

• enters low power sleep mode

For this reason, the DT80 normally disables sleep mode while an Ethernet cable is connected (although this can be

overridden by setting P15 to 3 or 4.

If an Ethernet session is disconnected in this way, you may need to manually disconnect then reconnect in DeTransfer.

Using the DT80 FTP Server

The DT80 can also function as an FTP (File Transfer Protocol) server. You can use this mechanism to transfer data and

program files to and from the DT80. This is done by running an FTP client application on the host computer and using it

to connect to the DT80's FTP server (by specifying the DT80's IP address).
