Universal LINC485
REPEATER/ROUTER
SPECIFICATIONS
The Universal LINC485 Repeater/Router provides a
simple, universal method for segmenting or extending
a YORK ISN Local Area Network (LAN). This small,
economical device can be located exactly where
needed in a small space with minimal setup time and
configuration effort.
By using DIP switches on the device, the Universal
LINC485 may be configured to function as a repeater,
extending the length of the network, or as a router,
dividing the network into subnetworks. The DIP
switches are also used to set the subnetwork address.
The DIP switches eliminate the need to connect a
computer and set software, as required for many types
of devices.
When functioning as a repeater, the Uni versal
LINC485 extends a network or subnetwork beyond the
4000 ft. (1220 m) and 31 node RS485 limitation. A
maximum of 2 repeaters per network or subnetwork
allow an overall length of 12,000 ft. and maximum of
92 nodes on a network (91 for a subnetwork).
When functioning as a router, the Universal LINC485
provides communication management between sub-

Features and Benefits
• Extends network length from 4000 ft.
(1220 m) to 12,000 ft. (3660 m).
• Increases network “size” to 92 subnetworks with over 8000 controllers.
• Single device functions as either a
repeater or router, simplifying stock and
inventory requirements.
• Simple DIP switch setup facilitates a
wide variety of network configurations
without a computer interface.
• DIN rail mounting is standard.
• Visual indicators of operating and communication status.
• UL916 pending. Complies with relevant
CE EMC and safety directives.

networks and the main network. Packet information is
not transferred beyond the Universal LINC485 unless
a different subnetwork is addressed. This limits the
overall traffic throughout the network by keeping
“local” data within the local sub-network.
Connection to the LAN is completed using a twistedpair, shielded cable attached to individual screw
terminals. 5 VDC power can be supplied from either
an optional power supply or directly from the network,
if located within 3 ft. (1 m) of a newer controller
equipped with a USB-style connector.
When located in a more remote location, a separate
5 VDC Power Supply is available for connection to a
115/230 VAC power source. DIN rail mounting is
standard for the Universal LINC485 as well as the
optional Power Supply. For additional versatility, the
LINC may be attached directly to the Power Supply
and the assembly mounted on a DIN rail or fixed
directly to a panel.
The Universal LINC485 operates on ISN networks
which use Rev. 6, Rev. 7, or UCS software. A DIP
switch sets the Universal LINC485 to operate at a
network transfer speed of either 19.2 or 50 kbaud.
A System Status LED provides information on the
operating condition of the device. Two additional
LEDs at each port provide information concerning the
communication status of each port.
The Base Network may contain a combination of up to 92 subnetworks or
nodes, providing Repeaters are used between segments of 32 RS485 drivers.

Connection
To provide simple connection the Universal LINC485
uses the same connectors as all YORK ISN controllers-a removable, 5-screw press-in connector. In
addition to the screw connector, newer ISN controllers
utilize a USB-style connector. This additional connector provides a simple method for connecting Universal
LINCs to the controller. If within 3 ft. (1 m) of a newstyle controller equipped with a USB-style LINC port,
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).
sufficient power is provided through the LAN connection. For installations at greater distances and older
controllers, an optional 5 VDC Power Supply is
available.
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.)
