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.
