Command Structure

4.3Command String

A command string consists of multiple commands on one line. The maximum length of a command string is 32 characters. All command strings are terminated by the Carriage Return <CR> code (0DH hex).

Example : FR2000SE 2300PL<CR>

NOTE: Assign the following commands individually.

•The Real Time Clock Set [WW]

•Print Character [PR]

•Blackboard/Stack Data Upload [BU]

•Blackboard/Stack Data Download [BD]

•Weekly Timer Data Upload [WU]

•Weekly Timer Data Download [WD]

•Text File Data Upload [UU]

•Memory Data Upload [MU]

Once the <CR> termination command is added to the string, the command string is executes from left to right in sequential order.

If an error occurs during the execution of a String, the remainder of the string following that command is ignored.

If a new command string is input before the current string executes completely, the current string is aborted and the remaining commands are cleared.

To cancel an executing string, send the termination command <CR> alone.

If a new command without Text File Data Upload [UU], [?*], [#*] or [$*] is input while playing the current command stack, the remaining commands are cleared.

The DVD-V7400 does not accept other commands during the execution of a Search command, returning an E04 error message. After issuing a Search command, wait until the Return (R) status appears before issuing another command. An exception to this rule is the Mark Frame Play command (i.e. FR1200PL), when it is unnecessary to wait for the R status before sending additional commands.

4.4Status Returns

The completion message used in the Automatic Status is R.

Example: R<CR>
