4. Install the MediaLink Controller.
TIP: Before cabling and installing the
MLC 104 IP Plus, locate the device MAC
address printed on a label on the bottom of
the controller. Write down the 12 character
alphanumeric address, (for example,
00-05-A6-03-9G-H4) and use when
configuring the IP address.
When cabling, the length of exposed wire is
critical to avoid transmission problems. Ensure
the lengths given here are adhered to when
stripping 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 at
right. To do this, strip the outer jacket back
to the length appropriate to get the red and
black leads to the switcher power supply. Trim
the white/purple/drain short enough to plug
directly in to the switcher, keeping most of the
drain covered in the jacket.
