INSTALLING YOUR MT105-110/111 6
Step 1. Slide the MT105-110/111 into an available
slot in the Multi-Tasker™ Enclosure in
order to connect to the bus. Make sure
that the MT105-110/111 card fits into
place. Secure the card to the Multi-
Tasker™ by tightening the retainer
screws located on the top and bottom of
the MT105-110/111 card.
Step 2. Connect a coaxial cable from the video
source to the input connector of the
MT105-110/111. Connect the output
connectors of the MT105-110/111 to the
display devices through a coaxial cable
Step 3. Starting from the left, identify the slot
number where the MT105-110/111 card is
plugged into the Enclosure and note that
it for RS-232 control.
OPERATION 7
7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT105-110/111 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 MT105-110/111
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).
7.2 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.
Card ID is an assigned value from 1 to 19 (1 to
8 or 1 to 2 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 MT105-110/111 card
Command Format: [VERCnUi
Cn = card ID (n = slot # from 1 to 19)
Ui = Unit ID (i = # from 0 to 9) (refer to the
MT100-100 user’s guide for explanation
