7. Operation
7.1 RS-232 Control
The MT115-111 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 MT115-111 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
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.
7.2 Description of Commands
Each command consists of three parts: Function, Card ID, and Unit ID.
[ Function , Card ID , Unit ID ]
Example: [VERC3U2]
VER = Function
C3 = Card ID or Group ID
U2 = Unit ID (optional for Unit ID 0)
For Function, see a detailed explanation under each command
description.
The card ID is a unique identifier. It is equal to the enclosure slot
number, or it may be an assigned value. As the slot number, the value
can range from 1-4 up to 1-20 depending on the enclosure. If the value
is assigned, the ID may be a maximum of 99. Card ID 0 (C0) is used for
the controller and cannot be reassigned.
The group ID is a number representing a group of cards defined with
the [WR] command. When using the group ID, all cards in the group
will perform the given instruction.
NOTE: In this guide, cards are referenced by their IDs (C1, C2...C99).
Typically, the ID number will be equivalent to the slot number.
Groups will be referenced by their IDs (G1-G8).
Changing the position of a card will significantly affect the commands
recorded on software definitions or third-party control systems.
The unit ID has a range from U0 to U20. U0 should be used for single
unit operation. If the ID is set to U0, each command may be used
without Ui. Use the command [SETU0], as explained in the
MT101-101 User’s Guide.
Example:
[VERC3]: For U0
[VERC3Ui]: For ID other than U0
[VERC3]: Equivalent to [VERC3U0].
Command Organization
The RS-232 commands in this section are organized into the following 5
categories:
Basic Commands
Feedback Control
Card Control
Card IDs
Groups
See the Summary of Commands (Section 7.3) for one line descriptions of
each command.
Basic Commands
The basic commands are used to provide general information about the
card. These commands are most useful during the initial stages of setting
up and operating the card.
1. [VER]
This command displays the software version and card type for the
MT115-111 card.
Command Format: [VERCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
An MT115-111 card is in slot 4. Send the command [VERC4], and the
system will return feedback similar to the following:
[MT115-111 690-0231-001 C04]
MT115-111 = Card model number
690-0231-001 = Firmware version
C04 = Card ID
