Connection
To provide simple connection the Universal LINC485
uses the same connectors as all YORK ISN control-
lers-a removable, 5-screw press-in connector. In
addition to the screw connector, newer ISN controllers
utilize a USB-style connector. This additional connec-
tor provides a simple method for connecting Universal
LINCs to the controller. If within 3 ft. (1 m) of a new-
style controller equipped with a USB-style LINC port,
sufficient power is provided through the LAN connec-
tion. For installations at greater distances and older
controllers, an optional 5 VDC Power Supply is
available.
Mounting Configurations
The Universal LINC485 provides several mounting
methods for greater installation flexibility. Shipped in
a housing with a DIN rail mounting clip, the unit can
be attached to any open DIN rail space within an
existing controller. If the controller does not use DIN
rail, the Universal LINC can be removed from the
housing and secured inside the controller with small
screws (1/8 in./4 mm or smaller).
If space is unavailable inside the controller enclosure,
a small, auxiliary enclosure is available. The auxiliary
enclosure includes a DIN rail to mount the Universal
LINC and an accompanying 5 VDC Power Supply. (It
also accepts the TDCE controllers.)
