4.3. Command Interface
The command interface is a new addition to version 4 of the converter's firmware. This interface has been
developed primarily to support programming access to the configuration settings by an application such as our own
configuration application, but can also offer a powerful human operated (e.g. via HyperTerminal) command driven
interface in it's own right. Additionally, the commands can be placed in a Text/script file and sent (e.g. by
HyperTerminal) in one go to the converter. The <scr> command is strongly recommended for use in this scenario.
The command interface protocol is quite straightforward. Each command (see table and descriptions below) must
be sent over the COM port, followed by a Carriage return. This can be done in HyperTerminal just by typing each
command and hitting the Enter key.
There are up to 3 ways each command can be used.
1. On its own. This acts as a "query" command.
e.g. cod<CR>
Returns the current device class
2. With an "=" and parameter(s). This acts as a "set" command
e.g. cset=9600,n,1<CR>
Sets the current settings to 9600 baud, No Parity and 1 Stop Bit
Not all commands support this function as they are query commands only
3. With a "?" which acts as a "help" command
e.g. svc?<CR>
Returns a description of the command syntax and allowable parameters
The command list summary is given below.

The full command list syntax and programming examples will be given in a future edition of this manual. In the
meantime, this information can be found using the help or ? command in HyperTerminal when your converter is
attached to an available COM port.
