The computer is used for changing setpoints, monitoring data, trend logging, diagnostics, and
remotely clearing alarms within the MicroTech system. The computer is normally a dedicated personal
computer, however, the operator may choose to exit the Monitor program from time to time to perform
other functions such as word processing or data manipulation using a spreadsheet program. It
should be noted, however, that for maximum convenience and functionality, the computer should be
considered a dedicated computer for the MicroTech system.
The communications cable from the unit control panel to the personal computer is shielded, twisted
pair wire (Belden #8761 or equal). The communications adheres to the industry standards of RS232C
and the rate of communications is 9600 baud. The recommended maximum distance from the personal
computer to the control panel is 50 feet. If the required distance is in excess of 50 feet, an optional RS232 extension kit is required (contact McQuay).
A voice quality, direct dial telephone line is required if remote access and monitoring of the unit
controller is desired. The phone line should be terminated with a standard RJ-11C modular phone
plug.
