Step 2. Secure the card to the Multi-Tasker™ by
tightening the retainer screws located on
the top and bottom of the
MT105-120/121.
Step 3. Connect a VGA cable from the video
source to the input connector of the
MT105-120/121.
Step 4. Connect the output connectors of the
MT105-120/121 to the display devices
through a VGA cable.
Step 5. Starting from the left, identify the slot
number where the MT105-120/121 card
is plugged into the Enclosure and note
that it is for RS-232 control.
OPERATION 7
7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT105-120/121 has many advanced remote
control capabilities, which are accessible through
standard RS-232 communication. The actual
controlling can be accomplished through a
computer control system or any other device
capable of sending RS-232 commands.
7.1.1 RS-232 INTERFACE
The RS-232 commands, for the
MT105-120/121, are in a simple ASCII
character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
After processing a command, an OK or ER 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.
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
For Function, see a detailed explanation under
each command description.
The Card ID is an assigned value. It is equal to
the enclosure slot number in which the card is
installed. The value can range from 1 to 4 up to
1 to 20 depending on the enclosure.
Card ID 0 (C0) is used for the controller. See
the MT100-100 User’s Guide for details.
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.
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 value from 0 to 9. Unit ID 0
should be used for single unit operation. If the
Unit ID is set to zero, each command may be
used without Ui. Use the command [SETU0],
as explained in the MT100-100 User’s Guide.
Example:
[VERC3]: For Unit ID Zero
[VERC3Ui]: For Unit ID other than Zero
[VERC3]: Equivalent to [VERC3U0]
