7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT103-122 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.
Step 2. Slide the MT103-122 into an available slot
in the Multi-Tasker™ Enclosure in order to
connect to the bus. Make sure that the card
fits into place. Secure the card to the MultiTasker™ by tightening the retainer screws
located on the top and bottom of the card.
7.1.1 RS-232 INTERFACE
The RS-232 commands, for the MT103-122, are
in a simple ASCII character format.
Step 3. Turn the enclosure power on or reset the
enclosure and verify the LED near the top
of the unit is illuminated RED indicating
power is applied.
Step 4. Connect the video source to the
MT103-122,
either
RGBHV/YPbPr,
S-Video or Composite Video. Verify the
LED turns green if using an RGBHV signal.

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 ending 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 or powered OFF then ON.
Step 5. Connect the audio source to the AUDIO
INPUT jack.
Step 6. Connect the CAT-5/6 cable from the video
output of the MT103-122 Transmitter to the
CAT-5 Input port on the MT103-123 or
equivalent receiver.
7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts: Function,
Card ID, and Unit ID.
[ Function , Card ID , Unit ID ]
Step 7. Verify the picture quality on the receiving
monitor is equivalent to the quality as
displayed on a local monitor. If the quality
of the image is poor or non-existent, it may
be necessary to adjust the Video
Equalization on the MT103-122 and/or
MT103-123. If hardware controlled, adjust
from the knob on the panel. For software
control, see the OPERATION section that
follows for details on the [EQ] command.

7.4.2 USING MENU MODE
SUGGESTION: Before using the menu mode, it
is best to disable the automatic feedback feature.
The values and current settings will be displayed
in the menu mode, but the automatic feature will
display after each setting change making the
menus difficult to read.
7.4 MENU MODE
MENU MODE commands are RS-232 commands
that allow virtually the same functionality as
programming commands. Unlike the programming
commands in the previous sections, 7.2 and 7.3,
MENU commands prompt the user to select from a
list of available options. The system then responds
based upon selections made by the user.
MENU commands may be issued in response to
prompts from within MTSetup™ or other RS-232
communication software.
The MENU driven commands are only available with
Multi-Tasker™ Front Panel systems that have the
following firmware:
690-0122-015 = Version 015 or later.
690-0123-004 = Version 004 or later.
690-0124-015 = Version 018 or later.

adjustments
on
the
MT103-122 and MT103-123 work together to
provide equalization for maximum cable lengths.
For example, for cable runs less than 50 feet,
both equalization settings may be set to
approximately minimum, since on the short
distances no equalization is required. Where as
cable runs of 400 feet will see equalization
settings at about the three-quarter position.

Card cage slot has a problem.
Solution 1: Test the card in other slots of the
card cage. If the slot was damaged,
the card may work in other slots. If
other slots work and the card is
recognized, the problem is the card
cage slot. The card cage may require
service.
Call
ALTINEX
at
(714) 990-2300. If the other slots do
not work, see Solution 2.
Solution 2: Take any other known good card and
verify that the slot used is good by
seeing if the other car is recognized
in that slot. If it is, then the original
card may be the source of the
problem.
