before the hard drive was damaged, I used an MJ20-22-CS25 cable and its usb converter together with the u90 ladder version 6.4.0 on my previous hard drive and it worked correctly.

OMG it worked!!! Thank you. I was all day trying to solve this problem. Sorry I have another PLC Jazz but JZ10. It does not have that port, it should make a new topic or I can use this topic since the error is the same.

I attach an image. I use the same COM3 port and the same cable for another plc using the visiLogic program and it works perfectly.

I'm using COM 3 on both my laptop and U90 Ladder

Hi guys, i have one problem in my plc Jazz JZ20-R31, problems the connected. I use 1- U90 Ladder V6.6.45 2- Cable MJ20-22-C525 3- Cable Adapter db9 (Serial) to usb 4- have Windows 7 Ultimate x64 bit The mistake he gives me is Communications could not be established due to one of the following: - Cable Connections are not secure - TimeOut is too short - Incorret communication settings. Check your cables and communication settings and try again. Previously it worked for me but I had some problems and I was forced to change my hard drive, without being able to obtain the information. I apologize in advance for my English, it's not very good. Thank you!
