This document provides additional assistance with wiring your Extron IP Link enabled product to your device. Different components may require a different wiring scheme than those listed below. For complete operating instructions, refer to the user s manual for the specific Extron IP Link enabled product or the controlled device manufacturer supplied documentation.

Driver Notes: An example GC and corresponding Nexia configuration for a single Scaled Volume command configured to an MLC 226 volume knob: 1. Within the Nexia software, be sure to name the Level Control block s Instance ID Tag to V1 (or any number ranging from 1 all the way up to 32, i.e. V1, V2, V3. V32). Page 3 of 8
2. When you re done with the Nexia software, open up GC and configure Volume Instance ID Tag 1 along with Volume Channel 1 and Scaled Volume. 3. Control your Nexia product! Page 4 of 8
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 Tag Letter Tag Range Corresponding Nexia Control Block Auto Answer A 1 ~ 16 TC - Receive (Double Click) Dial Keypad D 1 ~ 16 TC - Dialer (Double Click) Logic State L 1 ~ 32 Logic State Mute M 1 ~ 32 Mute Phone Input Level I 1 ~ 16 TC - Receive And Receive Mute Phone Output Level O 1 ~ 16 TC - Transmit and Transmit Mute Preset Recall N/A N/A Preset Button Hook D 1 ~ 16 TC Dialer (This logic resides in the Dialer block, use this command to hang up.
