This driver is not supported by the MLC62.
In order to use the MLC226/104 IP Plus/System 5 IP/TLP 700 volume knobs, configure the “Scaled Volume” command on the volume knob in Global Configurator.
Nexia uses an Instance ID number to specify the exact DSP block to be controlled. Custom names
(Instance ID Tags) may be assigned to DSP blocks, and used in lieu of Instance ID numbers within NTP (Nexia Text Protocol) command strings. Instance ID Tags may be up to 32 characters, but may not start with a number. If the
Instance ID Tag includes spaces, it must be double-quote delimited ("Instance ID Tag") when used in a command string. The Instance ID number (and Instance ID Tag) can be found by first making sure the “Properties” attribute of a control block is enabled by right-clicking the DSP block and selecting "Properties". Then hover over the
“Property Sheet” tab on the left and both identifiers are available in the DSP Attributes 1 tab.
To simplify instance ID tag naming within the driver, a capital letter and a number are used as the Instance ID Tag for a variety of control blocks.
The following Nexia configuration blocks correspond to the following driver commands: Command Name
