OPERATION 7
7.1 RS-232 CONTROL
The MT110-103 has many advanced
remote-control capabilities accessible through
standard RS-232 communication. Control may be
accomplished through a computer, control system,
or any device capable of RS-232 communication.
7.1.1 RS-232 INTERFACE
The control commands for the MT110-103 are in
a simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
3. Spaces are not legal characters.
The cards in a MultiTasker are capable of
performing various functions, as well as
providing feedback to the user or control
system. Commands instruct a card to perform
specific actions or request information from the
card. Some commands do both simultaneously.
A command that instructs the card only to
perform an action will generate feedback of “[ ]”.
The open bracket immediately followed by a
closed bracket indicates the card received a
valid command. If the command requested
information from the card, the feedback
generated by the card is the acknowledgement
of having received a valid command. Invalid
commands generate feedback that includes
“ERR” plus an error code.
Example 1: [ERR001] Error number
Example 2: [ERRC04] Card error C4
After processing a command, an “OK” or error
will be returned as feedback if “F” is included at
the end of a command string.
Commands ending in “S” will be saved into
memory. Commands not ending in “S” will still
be executed, but will not be restored when the
system is reset or powered off, then on.
