7

Example:

If one 

MT108-105

 card is plugged in slot #2 of

unit 3:

Send the command 

[VERC2U3]

, and the

Multi-Tasker™ Basic Enclosure will return the
following feedback:

MT108-105  690-0127-007

690-0127-007

 = software version

MT108-105 

= card type: MT108-105

2.  [C]

This command receives the status of the card.

Command Format: 

[CnUi]

Cn = card ID (n = from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)

Ui = unit ID (i = from 0 to 9) (refer to the
MT100-100 user’s guide for explanation)

Example:

If one 

MT108-105

 card is plugged in slot #2 of

unit 3, sending the 

[C2U3] 

command

,

 the

Multi-Tasker™ Basic Enclosure will return
feedback as:

Vol1=16/16
Vol2=12/16
Vol3=8/16
Vol4=4/16

There are 16 levels for amplitude.  In the above
example, Input 1 (Vol1) is at level 16 out of 16
or maximum amplitude.  Input 2 is at 12 or ¾
amplitude. Input 3 is at ½ volume and Input 4 is
at ¼ volume.

If there is no card plugged into slot #2 of unit 3,
the Multi-Tasker™ Basic Enclosure will not
return any feedback.

3.  [CiS]

This command saves the current status of the
card's output volume configuration. This
configuration will be restored after system is
reset or powered off then on.

Ci = card number

S = save configuration

If Outputs 1 and 2 are at volume level 16 and
outputs 3 and 4 are at level 8, the feedback
after sending the command [C4S], for slot 4,
would be:

Vol1=16/16
Vol2=16/16
Vol3=8/16
Vol4=8/16

Card Status Saved

4.  [ + ] or [ - ]

This command increases or decreases volume.
It immediately follows the [SEL] command. Any
command other than [ + ] or [ - ] will reset the
previous selection and the [SEL] command will
need to be reissued.

Example:

If the status of audio card 2 of unit zero is as
follows:

Vol1=16/16
Vol2=0/16
Vol3=0/16
Vol4=0/16

Send the commands:

[SEL1C2] [ - ] [ - ]
[SEL2C2] [ + ] [ + ]
[C2]

The new status will be as follows:
Vol1=14/16
Vol2=2/16
Vol3=0/16
Vol4=0/16

Note: The [SEL], [ + ], and [ - ] commands can
also be used to control the volume for a group
of cards.

Command Format: [SELmGkUi]

SELm = select output  (m = from 1 to 4)
Gk = group number (k = # from 1-9)
Ui  = unit id (i = # from 0-9)
