Hi,
I am trying to connect to a 1747-L542 (also an L543) via RS232.
I am using a desktop PC running windows 7 and RSLinx Classic and RSlogix installed. The PC has a native serial port in the back.
I am using a 3meter long DB9-DB9 null modem cable with a pinout similar to a 1747-CP3 that has this pin connections:
1st 2nd
DB9 DB9
1 - NC
2 - 3
3 - 2
4 - 6
5 - 5
6 - 4
7 - 8
8 - 7
9 - NC
I also have a CompactLogix 1769-L32E and using the same configuration as above, i can connect to it, see the HW config and upload the program inside.
But when I connect to the 5/04 (any of the 2) and I try adding a new DF1 driver in RSLinx I get the error in the attached foto. What am I doing wrong?? The 5/04s were used in a factory and presumably they were working before.
