After processing a command, an OK or ER will
be returned as feedback if "F" is included at the
end of a command string or if the unit ID is zero.
INSTALLING YOUR MT104-102
6
Step 1. Slide the MT104-102 into an available slot
in the Multi-Tasker™ Enclosure in order to
connect to the bus. Make sure that the
MT104-102 card fits into place. Secure
the card to the Multi-Tasker™ by
tightening the retainer screws located on
the top and bottom of the MT104-102
card.
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
Step 2. The LED on the card panel will turn red
indicating that the card is in full operation.
A green LED indicates that a signal is
present. An LED that is blinking red
indicates that the card is experiencing a
problem. If the LED is blinking, see
Troubleshooting Guide in section 8.
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
Step 3. Connect a coaxial cable from the video
For function, see a detailed explanation under
each command description.

output
Card ID is an assigned value from 1 to 19 (1 to 8
or 1 to 2 depending on which enclosure is being
used), which represents the number of slots.
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.
connectors of the MT104-102 to the
display devices through a coaxial cable.
Step 4. Starting from the left, identify the slot
number where the MT104-102 card is
plugged into the Enclosure and note that
it is for RS-232 control.
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).
OPERATION
7
7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT104-102 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.
Example:
[VERC3]: for unit ID zero
[VERC3Ui]: for unit ID other than zero
[VERC3]: equivalent to [VERC3U0]
1. [VER]
7.1.1 RS-232 INTERFACE
This command receives the software version and
card type for the MT104-102 card.
The RS-232 commands for the MT104-102 are in
a simple ASCII character format.
