cklundquist Posted March 8, 2013 Posted March 8, 2013 I experienced problems with serial ports and usb-serial port adapters under windows 7. After much trial and error the solution is run PEWin in XP compatibility mode. This solved the issue on my HP and Dell laptops, as well as my desktop machine.
Omron Forums Support Posted March 12, 2013 Posted March 12, 2013 Thanks for the information. Was this for PeWin32Pro, or PeWin32Pro2?
Faraday MC - Tony Posted March 13, 2013 Posted March 13, 2013 If your USB-RS232 converter has an FTDI chipset you need to go into device manager and find the port, double click it to bring up properties and then select port settings. Click the Advanced button and find the Latency Timer. This is usually set to 16 but if you reduce it to 4 or less the Pro2 suite programs will communicate more reliably.
