I'm wanting to upload the program from a CompactLogix L31 Controller. I'm using a generic (non Allen Bradley) "C2G brand" usb -->rs232 cable coming directly off of my laptop because I don't have a serial port out. The rs232 side of the C2G cable is a "pin out" or male end, and as you can see in the attached picture, the serial port at Channel 1 on the controller is also male. I'm using a generic (non-Allen Bradley) null modem (female-->female) cable to complete the connection. Ultimately, I'm not seeing the controller on linx. But that's a result of me not being able to configure the driver. When I try to auto configure this driver, Linx gives me an error saying, "Unable to verify settings due to a NAK!"
I have used the -USB to serial- cable with some micrologix controllers and have successfully gone online and uploaded programs from them. But the secondary cable that came after the -USB to serial- cable was an Allen Bradley 1761-CBL-PM02 serial cable.
btw, the rs232 cable going into channel 0 is for the HMI on the machine. A pv600
1. How do I get online and upload the program from the controller?
2. What does NAK mean?
