I believe I need help with the proper cable connections to allow a 9-pin serial port on a laptoop to talk to a TI 530C Processor.
I am trying to help a customer program their TI 530C Processor. I am running TISOFT 2 Release 7.1 software. I was told to use an old computer, so I have a Windows 95 laptop. When attempting to connect, I exit windows to DOS, run the TI505.BAT file to launch TISOFT, this works fine. But I get "Communications Time Out" when selecting "Online-F4".
I have tried almost every possible baud rate. I am connecting the 9-pin serial port on the laptop to the 25 pin comm port on the bottom of the TI 530C PLC. Thought the cabling was correct but I am suspicious.
Using 2-2, 3-3, 5-7. 9-pin has 1-4-6 and 7-8 internally jumpered, 25 pin has 4-5 and 6-8-20 internally jumpered.
Any help would be greatly appreciated.
