3.4 CALCOMMS - Computer Interface (Optional)
CALCOMMS is a graphic Windows™ based software package designed for PC
supervision of CAL 3300 Controllers. It offers the capability of remote adjustment,
instrument configuration, cloning, saving and retrieving instrument settings to files
together with logging and charting in real time. Communications uses the MODBUS®
protocol via a fully isolated RS485 link.
To gain full benefit of CALCOMMS software, it is recommended that the PC be fitted
with a Pentium processor (although a 486 will work) and is running WINDOWS 95 or
Windows NT programs. A minimum of 16 MB RAM is recommended to run the program
(slightly less is OK), together with enough free hard disc space to meet logging
requirements.
