ABOUT YOUR MT103-118/120 2
MT103-118/MT103-120
Dual 1-in 3-out Video & S-Video Distribution
Amplifier Card
The MT103-118/120 is a dual 1-in 3-out Composite
(C) Video and S-Video Distribution Amplifier (DA)
Card. There is one BNC C-Video input with three
BNC C-Video outputs and one S-Video input with
3 S-Video outputs. It is designed for use in
Multi-Taskerenclosures. When installed in a
Multi-Taskerenclosure, this DA card enables the
connection of a single S-Video and/or Composite
video source to up to three displays or recording
devices each. On the MT103-120, each output
may be individually enable or disabled through
RS-232 control.
A variety of video signal formats can be
accommodated by using multiple DA cards in a
Multi-Taskerenclosure. For example, two
S-Video DA cards can be used to handle the two
components of an S-Video signal (Chroma and
Luma). To create a component S-Video distribution
amplifier, simply install three of the MT S-Video DA
cards, one each for the Y, Pr, and Pb (or Y, R-Y,
B-Y) signal components. Similarly, the MT S-Video
DA series cards can also be used to pass
computer video signals: 4 cards for RGBS and 5
for RGBHV.
The MT103-120 also features Equalization
adjustment. The equalization allows the user to
adjust the signal when long cable lengths are
involved. The Equalization circuitry is good for
cable runs up to about 250 feet when a high
quality 75 ohm coaxial cabled is used.

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 theMT103-120 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 theMT103-120 card.

Ui = Unit ID (i = # from 0 to 9) (refer to the
MT100-100 user’s guide for explanation)
Example:
If one MT103-120 card is in slot #2 of unit 3:
When sending command[VERC2U3],the Multi-
Tasker™ Enclosure will return feedback as
MT103-120 690-0125-010
MT103-120 = card type
690-0125-010 = software version
2. [C]
This command receives the status of the card.
Command Format: [CnUi]
Cn = card ID (n = a slot # from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)
Ui = unit id (i = 0 to 9) (refer to the MT100-100
user’s guide for explanation)
Example:
If one MT103-120 card is in slot #2 of unit 3
with S-Video outputs 1 and 2 ON and Video
Output 3 ON:
When sending the command[C2U3],the Multi-
Tasker™ Enclosure will return feedback as
SVID: 1,2 CVID: 3 C02
SVID: 1,2 = S-Video Outputs 1, 2 are enabled
CVID: 3 = Video Output 3 is enabled
C02 = card is in slot 2
If there is no card in slot #2 of unit 3, sending
the [C2U3] command will not return any
feedback.
3. [CiS]
This command saves the current status of the
card's output enable configuration. This
configuration will be restored after system is
reset or powered off then on.
Ci = card number
S = save configuration
If S-Video Outputs 1,2,3 and Video Outputs
1,2,3 are enabled, the feedback after sending
the command [C4S], for slot 4, would be:
SVID: 1,2,3 CVID: 1,2,3 C04 Saved
4. [ONnSCi]
This command enables one or more of the
S-Video outputs to be turned ON.
