Several data collection systems such as WinSPC, Infinity, etc require an RS-232 Serial Communication port for connection. MSEZ/CFEZ/D2NC all have USB outputs and can not be connected directly to these systems for data collection. The solution is to use the attached USB to Serial Bridge program on a Windows OS system. Download the zip file, install Runtime.msi and then run the USB2RS232 program. Select the com port you would like to use on the PC, and connect to you data collection system using that port.
