[M-90 T connection issue]

Hi

 

I have two old units but i haven't got original cable. I dont know if they work good so i tried to connect to them with my pl2303 rs232 to USB converter and an rj11 cable. Tried it on Windows 8.1 64bit and Windows 7 64bit. Evertime it say that it can't synchronise with PLC. I use proper COM and got good drivers and good settings. 

[Windows 8 and U90Ladder]

Did you solve the problem? If yes please tell how to make it working cause i have the same problem.
