Introduction To Open Protocol Network Configuration - McQuay MicroTech UV1S2 Series Protocol Manual

Introduction to Open Protocol Network Configuration

This section will be used to explain how the McQuay
works so that the correct equipment and program can be chosen to communicate through
MicroTech
There are two (2) types of controllers that are used to make an Open Protocol Unit Ventilator
Network. They are the Open Protocol Master (OPM) and the Unit Ventilators (UV's).
The OPM provides a single communications port entry into the McQuay Unit Ventilator network.
The OPM panel consists of an EnergyLine model 120 controller. The automation integrator
connects to Comm port A, which will be pre configured for RS-232, 9600 baud. Port A is the
automation control integrator's Open Protocol communications port. Comm port B is a daisy
chained, multi-drop, 9600 baud RS-485 proprietary McQuay International protocol.
The main function of the OPM is to provide network communication interface for up to 64 Unit
Ventilator controllers.
The unit ventilator controller is factory mounted. The unit controller replaces all controls with pre-
programmed, pre-engineered and pre-tested stand-alone control. There is one controller for each unit
ventilator.
In addition to this hardware, McQuay's Unit Ventilator Open Protocol Monitor Software package is
needed. This software is used to configure, commission, and troubleshoot the McQuay
communications system. The software contains diagnostic routines which can be used to
troubleshoot the McQuay network.
This software is MS-DOS compatible to be used in all IBM PC's or 100% true compatibles.
The Monitor Software is installed in the IBM or compatible PC, and the PC is connected to the OPM
port "A" as shown:
