FCI Communication > Commands to/from USC-Card

The general form to send data to the USC-3 is as follows:

•<Command> is an ASCII based command as described in this manual. All commands are not case sensitive.

•<Par1> to <ParN> are parameters 1 to N. The number of required and optional parameters depends on the FCI command.

Each command has a response by the USC-3 – please refer to section Commands From USC-3. It is not allowed to send a new command as long as the end of the return from a previous command is not received. Appropriate time out loops must be implemented. Please refer to the specific commands for more details on typical response times. Unless otherwise stated, response times are in the order of a few ms after the <END> is sent until the first character is returned.

Examples:

Send	JN 1<CR>	Select job number 1
Return	0:<CR>	Returns the error code '0' (Success)
Send	JN<CR>	Get current selected job.
Return	0:1<CR>	Returns the error code '0' (Success) and the current selected job which is the job '1'.

Command help:

A command followed by --HELP as parameter Par1 returns a short help to the specified command. Parameters in brackets, e.g. [<par1>], are optional.

Example:

Send	M --HELP<CR>	Request the command help of the M command.
Return	0: M [<par1>]: mark; 0 (stop), 1 (start)	Returns the error code '0' (Success) and the command help of the M command.
