INSTALLING YOUR MT108-102/(103)

6

Step 1.

Slide the 

MT108-102/(103)

 into an

available slot in the Multi-Tasker™ Basic
Enclosure in order to connect to the bus.
Make sure that the 

MT108-102/(103)

Stereo

 

Audio DA Card fits into place.

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

MT108-102/(103) 

Stereo

 

Audio DA Card.

Step 2.

The LED on the card panel will turn red
indicating that the card is in full operation.
A green LED indicates that an input signal
is present. An LED that is blinking red
indicates that the card is experiencing a
problem. If the LED is blinking, see the
Troubleshooting Guide in section 8.

Step 3.

Connect an audio cable from the audio
source to the input connector of the

MT108-102/(103)

. Connect any or all of

the four available outputs of the

MT108-102/(103)

 to audio equipment.

Step 4.

Starting from the left, identify the slot
number where the 

MT108-102/(103) 

card

is plugged into the Enclosure and note
that it is for RS-232 control.

OPERATION (for MT108-103 only)

7.1  RS-232 CONTROL

The outputs of the 

MT108-102

 are always

enabled; therefore, no RS-232 control is
necessary.

When used in the Multi-Tasker™ Basic
Enclosure, the 

MT108-103 

has many advanced

remote control capabilities, which are accessible
through standard RS-232 communication. The
actual control may be performed using 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 

MT108-103 

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.

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.

The Card ID is an assigned value from 1 to 19,
based on which slot the card is put in. The 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 of the 

MT108-103 

card.

Command Format:

 

[VERCnUi]

Cn = card ID number (n = # from 1 to 19)
