Installation

Step 1: Get ReadyUse the following check list to prepare for the installation.

� Download and install the latest version of the following:

• Global Configurator software — for setting up and configuring the controller. GC includes the Toolbelt feature and a way to upgrade the firmware of the controller. You must have an Extron Insider account and contact an Extron support representative to obtain GC software (see Locating Software, Firmware, and Driver Files on the Extron Website on page 10).

• IP Link Pro device drivers — for use with GC, to make control of other devices possible.

All are avail able from www.extron.com (see Locating Software, Firmware, and Driver Files on the Extron Website on page 10).

� Obtain network information for the unit from the network administrator. You will need the following details for each IP Link Pro device:

� DHCP setting (on or off) � Subnet mask � User name � Device (MLC Plus 84) IP address � Gateway IP address � Passwords

� Write down the MAC address of each IP Link Pro device (such as the MLC Plus 84) to be used.

� Obtain model names and setup information for devices the MLC Plus 84 will control.

Step 2: Prepare the Installation Site

ATTENTION:

• Installation and service must be performed by authorized personnel only.• L’installation et l’entretien doivent être effectués par le personnel autorisé uniquement.

• Extron recommends installing the MLC Plus 84 into a grounded, UL Listed electrical junction box.• Extron recommande d’installer le MLC Plus 84 dans un boîtier d’encastrement électrique mis à la terre, listé UL.

• If the controller will be installed into fine furniture, it is best to hire a licenced, bonded craftsperson to cut the access hole and perform the physical installation so the surface will not be damaged.

• S’il est prévu d’installer le contrôleur dans du beau mobilier, il est préférable de faire appel à un artisan autorisé et qualifié pour couper le trou d’accès et réaliser l’installation de telle façon que la surface ne soit pas endommagée.

• Follow all national and local building and electrical codes that apply to the installation site.• Respectez tous les codes électriques et du bâtiment, nationaux et locaux, qui s’appliquent au site de l’installation.
