Altinex MT110-100/102 manual Volume Ramping Feature MT110-102 only

MULTITASKER™

Example:

There is an MT110-102card 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]
