ABOUT YOUR MT103-121

MT103-121

1-in 6-out CAT5 Distribution Amplifier

2

The MT103-121 is a CAT5 audio/video distribution amplifier (DA). It is designed to be used with Altinex

CAT5 Transmitters and Receivers, including part numbers DA1930CT, DA1931CT, DA1920SX and

DA1921SX.

The MT103-121 is a 1-in 6-out DA Card. There is one CAT5 input and there are six CAT5 outputs.

This card enables the connection of a single CAT5 transmitter to six CAT5 receivers.

The MT103-121 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 400 feet when high quality cabled is used. The total distance from source to transmitter to receiver to display is 700 feet at resolutions up to

1024x768. An on board switch allows the user to choose between hardware and software control of

Video Equalization.

Another feature available is the Loop Output. This output allows the same input to the MT103-121 to be easily connected to another MT103-121 or similar device. Switch settings allow the user to select between Loop Output or no Loop Output.

INSTALLING YOUR MT103-121 6

Step 1. Determine if the Loop Output is going to be connected to another card input. If the

Loop Output is going to be used, set switches SW2, SW3 and SW4 to the OFF position. See DIAGRAM 3 on page 7 for details.

Step 2. Determine if Video Equalization will be controlled through hardware or software. If

Equalization is to be software controlled, set switch SW5 to the SW position. See

DIAGRAM 3 on page 7 for details.

Step 3. Slide the MT103-121 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

Multi-Tasker™ by tightening the retainer screws located on the top and bottom of the card.

Step 4. If the power is ON, the LED on the card will turn red indicating that the card is in full operation. If the LED does not come on, it may be necessary to reset the system or turn the system power off and then back on. If the LED is blinking, see

Troubleshooting Guide in section 8.

Step 5. Connect a CAT5/6 cable from the CAT5

Transmitter to the input connector of the

MT103-121 card.

Step 6. Connect at least one of the output connectors to a CAT5 Receiver through a

CAT5/6 cable. The outputs are always on, so the display connected to the CAT5

Receiver should have a display present.

Step 7. Starting from the left, identify the slot number the MT103-121 card is plugged into, and note that it is for RS-232 control.

MULTI-TASKER™

OPERATION 7

7.1 RS-232 CONTROL

When used in the Multi-Tasker™ Enclosure, the

MT103-121 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 MT103-121, 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 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.

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 or Group ID

U2 = Unit ID

For Function, see a detailed explanation under each command description.

8

The Card ID is an assigned value. It is equal to the enclosure slot number in which the card is installed. The value can range from 1 to 4 up to 1 to 20 depending on the enclosure.

Card ID 0 (C0) is used for the controller. See the

MT100-100 User’s Guide for details.

The Group ID is a number representing a group of cards defined with the [WR] command. When using the Group ID, all cards in the group will perform the given instruction.

Changing the position of a card will significantly affect the commands recorded on software definitions or third party control systems.

The 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 zero, each command may be used without Ui. Use the command [SETU0], as explained in the MT100-100 User’s Guide.

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 MT103-121 card.

Command Format: [VERCnUi]

Cn = Card ID (n = slot # from 1 to max slots)

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.

NOTE: In MTSetup™, send the command [VER] from the Terminal Window. The system will respond with feedback similar to the following:

[690-0122-015 690-0123-004 690-0124-018]

Check the last three digits against the numbers above to determine if the MENU MODE option is available.

TROUBLESHOOTING GUIDE 8

We have carefully tested and have found no problems in the supplied MT103-121. However, we would like to offer suggestions for the following:

8.1 CARD IS NOT RECOGNIZED

Cause 1: The card is not recognized.

Solution: Reset the card cage by sending the

[RES] command, or turning the system power off and then on again.

Send the [C] command to see if there is communication with the card. If there is no feedback, see Cause 2.

Cause 2: Card is not plugged in all the way.

Solution: Push the card in all the way. Reset the system and send the [C] command. If the card is still not recognized, see Cause 3.

Cause 3: 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. Call ALTINEX at

(714) 990-2300.

8.2 NO DISPLAY

Cause 1: The source has a problem.

Solution: Check the source and make sure that there is a signal present and all source connections are correct. If the source is working and there is still no display, see Cause 2.

Cause 2: Cable connections are incorrect.

Solution: Make sure that cables are properly connected. Also, make sure that the continuity and wiring are good. If there is still no display present, see

Cause 3.

Cause 3: There is no input signal.

Solution: Verify the card is receiving a valid signal at the input using the Signal

Detect command, [SIG]. See RS-232 accessible commands in

Section 7. If no signal is detected, see Solution 2. If a signal is detected, see Cause 4.

Solution 2: Connect the Transmitter and

Receiver directly, bypassing the

MT103-121. If there is no display, there is a problem with the

Transmitter or Receiver. If the display is good, see Cause 4.

Cause 4: Equalization is set too high.

Solution: Make sure the equalization is set to minimum to start. If controlling the equalization using the built-in potentiometer, verify the EQ switch on the board is set to HW. See

DIAGRAM 3: JUMPER SETTINGS for details.

Cause 5: The display has a problem.

Solution: Make sure that the display has power and is turned ON. If there is still no display, call ALTINEX at

(714) 990-2300.
