INSTALLING YOUR MULTI-TASKER™ 6
Step 1. Slide the MT104-108 into an available
slot in the Multi-Tasker™ Enclosure in
order to connect to the bus. Make sure
that the MT104-108 card fits into place.
Secure the card to the Multi-Tasker™ by
tightening the retainer screws located on
the top and bottom of the MT104-108
card.
Step 2. The LED on the card panel will turn red
indicating that the card is in full operation.
Step 3. Connect a coaxial cable from the video
source to the input connector of the
MT104-108. Connect the output
connectors of the MT104-108 to the
display devices through a coaxial cable.
Step 4. Starting from the left, identify the slot
number where the MT104-108 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
MT104-108 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 MT104-108 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 such as [ON], [OFF], and [IO] that
end 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 (power off & power on again).
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
U2 = Unit ID
For Function, see a detailed explanation under
each command description.
The Card ID is an assigned value from 1 to 19,
1 to 8, or 1 to 4 depending on which enclosure
is being used. The Card ID represents the slot
number where the board resides. Card
ID 0 (C0) is used for the controller (see user’s
guide for the MT100-100). Changing the
position of a card will significantly affect the
commands recorded on software definitions or
a third party control system.
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 0, then each command can be
used without Ui (use command [SETU0]; see
user’s guide for the MT100-100).
Example:
[VERC3]: for unit ID zero
[VERC3Ui]: for unit ID other than zero
[VERC3]: equivalent to [VERC3U0]
1. [VER]
This command receives the software version
and card type for the MT104-108 card.
Command Format: [VERCnUi]
Cn = card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9) (refer to the
MT100-100 user’s guide for explanation)
