8

Example:

If cards 1, 2, and 3 are grouped as group 5 of
unit 1, send the command [SEL1G5U1].  Then
send the commands [ + ], and [ - ] to increase
or decrease the volume for cards 1, 2, and 3
simultaneously.

5.  [SEL]

This command selects the individual input for
adjusting the volume level of each output.

Command Format: [SELmCnUi]

SELm = volume select for output m. (m = 1-4)

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)

After the [SEL] command is executed, the [ + ]
and [ - ] commands must be executed
immediately in order to increase or decrease
the volume.  Any other command (or an empty
command such as [ ] ) will terminate the [SEL]
command.

6.  [VOL]

This command allows the Multi-Tasker to send
an absolute volume level to the 

MT108-105

.

Command Format: [VOLmAnCi]

VOLm = output select (m = 1 to 4)

An = amplitude level (n = 0 to 16)

Ci = card ID (i = from 1 to 19)

(1-8 for MT100-101 or 1-4 for MT100-106)

Ui  = unit ID (i = from 0 to 9)

Example:

If there is an MT108-105 card in Slot 4 of
Unit 0, sending the command [VOL1A16C4] will
set the volume of output 1 to the maximum level
of 16.

7.  [CLR] - Card

The command clears all volumes to maximum
for a single card. With this command, 200ms is

needed for execution. Insert a 200ms delay
[WAIT] time after sending this command.

[CLRCnUi]

Cn = card ID No. (n = slot # from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)

Ui = Unit ID number (i = 0 to 9)

After [CLR] is executed, send [Cn] and receive
feedback as:

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

8.  […S] – Save

This command will save the volume
configuration command being sent in memory.
When sending the command [VOL1A10C4

S

],

after reset or power up, the volume level of
output 1 on C4 will be level 10.

9.  [CLR] - Group

This command clears the members for all nine
groups.

[CLRGkUi]

Gk = group number (k = # from 1-9)

Ui = unit number (i = # from 0-9)

Example:

a)

To clear group #1, send the command
[CLRG1U1].  This command clears the
members for the specified group only.

b)

To clear all groups of unit 1, send the
command [CLR G

[

U1].

10.  [WR]

This command groups multiple cards in the
MT100-100 Enclosure. Each unit contains a
maximum of nine groups.

Command Format: [WRCn…GkUi]

Cn = card ID No. (n = slot # from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)

Gk = group number (k = # from 1-9)
