Okuma Cadet 4020 file transfer


Jul 6, 2020
I just bought a 1995 Okuma Cadet 4020 w/OSP 5020m control and I don't know how to transfer a program to the machine. I can get the programs out of the machine just fine. The connection is rs232 25 pin to 9 pin with an adapter to usb. I am not sure if there is something special you need to put in after you push read just before you hit write. If I just hit write I get error 2131. I have tried cn0: and hit write and it calls for the program because i can see the software start to send the program but it never gets to the control.

Any help would be great. Thanks.
