Description
The OE-364-22 MiniLink Polling Device is
a network controller that is used to inte-
grate multiple local communication loops
into a network communications system.
Network loop terminals of the MiniLink
Polling Device are designed to be con-
nected to the CommLink and to other
MiniLink Polling Devices on the network
communications loop. Local loop termi-
nals of the MiniLink Polling Device are
designed to be connected to controllers
installed on the local communications
loop. The MiniLink Polling Device can be
connected to the communication loops
and power loop of the system controllers
via modular cables that simply plug into
the MiniLink Polling Device board. This
virtually eliminates wiring errors and
makes installation fast and easy.
The MiniLink Polling Device utilizes token
passing communication architecture. The
MiniLink Polling Device is designed to
serve as the local communications loop
master. This means that it is responsible
for sending the token to all the controllers
on the local communications loop. Net-
work communications are of the RS-485
type operating at 19,200 baud. Local
communications are also of the RS-485
type and operate at 9600 baud. The
MiniLink PD is required for zoning sys-
tems to facilitate voting of the zones to
determine the HVAC units heating and
cooling mode of operation. It also pro-
vides tenant-logging capabilities.
Mounting
The MiniLink Polling Device is factory
mounted in a galvanized sheet metal en-
closure. Mounting holes are provided in
the enclosure for surface mounting.
