Thanks for the replies guys, so it is not possible to connect to the controller without special connector? There is no pinout diagram that I can use to hook up my RS232 cable?

Hey guys, We have a very old compressor from a turkish company that used this HMI to control it, the problem is that now we want to modify something and I can't figure out the way to connect to the plc. There are 10 pins on the communication port and I want to connect with RS232, I am guessing that this is a very old PLC model: JZ10-R16, MFG. CODE: M80-P1 I found a pinout here https://unitronicsplc.com/Download/SoftwareHelp/U90LadderKnowledgebase/Communications/Direct_Communications-_PC_to_PLC.htm but this only describes 6 pins and mine has 10 pins. Where can I find the correct pinout for my model? I also tried looking in the help menu of VisiLogic but could not find it there. Best Regards, Tod
