1. Double checked my cables and pinout. They are correct.
2. Had to go into device manager (windows xp) and setup the serial to usb converter. It was set to COM 6, and baud 9600. I left it at com 6, and selected 19,200. The other settings were correct.
3. Updated the new com port number into mach, but with no luck. Still wont open the "port" when i click open.
4. Found that all my settings i "entered" into the vfd through the keypad didn't save!! After selecting a setting and changing its value, you must hit the "STR" key (Save to ram) or it will not save any of your settings. Corrected this issue.
5. In modbus test (in mach), it will still not "open" com port 6. The correct drivers are loaded for the converter, and device manager says the device is working properly. What could it be?
I have the SW7 switch on 485, and SW8 set to off like the manual states for modbus operation. I also have all the settings programmed into the VFD and saved, per the manual specs. Com port 6 at 19200 baud is my usb to serial converter. Mach simply can't open the port.
What should I do?
Check out the pictures! Thanks.
