INSTALLING YOUR MT106-103 6
Step 1. Slide the MT106-103 into an available slot
in the Multi-Tasker™ Basic Enclosure in
order to connect to the bus. Make sure
that the MT106-103 card fits snugly into
place. Secure the card to the
Multi-Tasker™ by tightening the retainer
screws located on the top and bottom of
the card.
Step 2. Connect a cable from the video source to
the Composite Video input connector on
the MT106-103. Connect the output
connector of the MT106-103 to the
display device through a VGA cable.
NOTE: The Composite Video input is the
default input when powered up or first
plugged in.
Step 3. Starting from the left, identify the slot
number where the MT106-103 card is
plugged into the enclosure and note that it
is for RS-232 control.
Step 4. The default input selection is the
Composite Video port. In order to change
the input to other than Composite Video,
use MTSetup or other communication
software. Follow the instructions defined
in section 7.2 for the IN command, or
section 7.4 for MENU MODE.
OPERATION 7
7.1 RS-232 CONTROL
The MT106-103 has many advanced remote
control capabilities, which are accessible through
standard RS-232 communication. Actual control
may 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 MT106-103 are
in a simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
The cards in a Multi-Tasker™ system are
capable of performing various functions, as well
as providing feedback to the user or control
system. Some commands instruct a card to
perform specific actions. Other commands
request information about the status of the card.
Other commands do both at the same time.
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 a unique identifier. It is equal to
the enclosure slot number. The value can range
from 1 to 4 up to 1 to 20 depending on the
enclosure. (example: C1, C2, C3 … C20)
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.
Changing the position of a card will significantly
affect the commands recorded on software
definitions or third party control systems.
