MULTITASKER™
400-0132-005
19
Example:
There is an MT110-102 card in slot 8. Adjust the
volume level on Output 2. The current level is
set to 10. After sending the following
commands, a better level of 15 is obtained:
1. [SEL2C8]
The current output level is 10.
2. [ - ] [ - ] [ - ]
The level is now 7 and is too low.
3. [ + ] [ + ] [ + ] [ + ] [ + ] [ + ] [ + ] [ + ]
The level is now 15 and no further
adjustments are required.
32. [ + ] MT110-102 ONLY
This command increments a selected property
to be adjusted from the keyboard or front panel.
Command Format: [ + ]
[+] = Increment level by one-step
Example:
See the [SEL] command example.
33. [ - ] MT110-102 ONLY
This command decrements a selected property
to be adjusted from the keyboard or front panel.
Command Format: [ - ]
[-] = Decrement level by one-step
Example:
See the [SEL] command example.
VOLUME RAMPING FEATURE: MT110-102 ONLY
The following 7 commands are used to control the
volume of the MT110-102. They may be used with
computer control, but also are designed to be used
with the {SETVK} command using keys on the
Front Panel. The following code sample sets front
panel keys 8 and 10 to Ramp Up and Ramp Down
respectively. See your Front Panel User’s Guide
for more details.
When defined as a volume control key, the key will
respond to two conditions: press and release.
Below, subroutine 8 starts ramping up when key 8
is pressed. Subroutine 10 starts ramping down
when key 10 is pressed. Subroutine 108 stops
ramping when either key is released.
Since there are multiple outputs on this card, the
output to ramp must first be selected using the
[SEL] command. For example, send [SEL2C4] and
then [RDNC4] to ramp down the volume level on
Output 2 of C4. Then, send the [SEL2C4] and
[RUPC4] commands to ramp the level back up.
{WRS8=RUPC4} //Ramp Up
{WRK8=8,108,0,0,0} //Press= start, release= stop
{WRS10=RDNC4} //Ramp Down
{WRK10=10,108,0,0,0} //Press= start, release= stop
{WRS108=RSTC4} //STOP RAMPING
{SETVK8} //Set key 8 as volume key
{WRLK8=VOL_UP} //Define Key 8 Label
{SETVK10} //Set key 8 as volume key
{WRLK10=VOL_DN} //Define Key 8 Label
[RAMP=10C4] //Set the ramp rate.
34. [RUP] MT110-102 ONLY
This command ramps the output volume to its
maximum level at the rate defined using the
[RAMP] command.
Command Format: [RUPCnUi]
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
Ramp the output volume on Output 1 from a
starting level of 10 to the maximum level of 32
for the card in slot 8. Send the commands
[SEL1C8] then [RUPC8] and the system will
respond with the following feedback:
[11][12][13][14]…[32]
