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.
NOTE: The MLC 104 IP Plus is powered
from the PVS 305SA IP. DO NOT
connect an external power supply to
the MLC 104 IP Plus unless installing an
optional secondary control panel.
