INSTALLING YOUR MT103-118/120 6
Step 1. Slide the MT103-118/120 into an
available slot in the Multi-Tasker™
Enclosure in order to connect to the bus.
Make sure that the MT103-118/120 card
fits into place. Secure the card to the
Multi-Tasker™ by tightening the retainer
screws located on the top and bottom of
the MT103-118/120 card.
Step 2. The LED on the card panel will turn red
indicating that the card is in full operation.
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.
Step 3. Connect a coaxial cable from the video
source to the input connector of the
MT103-118/120. Connect the output
connectors of the MT103-118/120 to the
display devices through a coaxial cable.
Step 4. Starting from the left, identify the slot
number where the MT103-118/120 card
is plugged into the Enclosure and note
that it is for RS-232 control.
OPERATION (MT103-120 ONLY) 7
7.1 RS-232 CONTROL
The MT103-120 has many advanced remote
control capabilities when used in the
Multi-Tasker™ Enclosure and 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.
7.2 RS-232 INTERFACE
The RS-232 commands for the MT103-120 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
string will be returned as feedback if "F" is
included at the end of a command string or if
the unit ID is zero.
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).
7.3 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.
Card ID is an assigned value from 1 to 19 (1 to
8 or 1 to 4 depending on which enclosure is
being used); based on which slot the card is put
in. 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.
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 displays the software version
and card type for the MT103-120 card.
