Extron electronic 305SA Install MediaLink Controller, Connect the MLC 104 IP Plus to the switcher

4. — Install MediaLink Controller

TIP: Before cabling and installing the

MLC 104 IP Plus, locate and write down the

MAC address of the device for configuring the

IP address. The 12 character alphanumeric

address (for example, 00-05-A6-03-9G-H4)

can be found on a label on the side of the

controller. The length of exposed wire is critical

to avoid transmission problems. Ensure the

lengths given here are adhered to when strip-

ping the cables for connection.

NOTE: If a drain wire is used, both ends of the

wire must be covered by heat shrink to avoid

accidental grounding.

a.Connect the MLC power and RS-232 control cable (part number 26-626-50) as shown.
