Okuma Cadet 4020 file transfer

tamm248 · 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.

What handshaking software are you using?

What is the error message?

Man it's been a long time since I messed with that control.
I THINK you have to give it a program name then have the control read, then send it from your computer.
The program name HAS to start with a letter, and up to 16 characters max.
Has to have a .min extension
% at beginning and end of the program also.

Currently I am using Xon Xoff. The software is called PCdnc plus. My baud rate set on the computer is 9600.

9600 is way too much for OSP 5020. I would change it to 7200 or even 4800. I think the control defaults to 7200....maybe.

I'd follow Mtndews instructions. I name all my programs A.MIN for transfer, for si.plicity, then change it after. I don't store unused programs in the control. The control needs to be 'read'ing before you send from the PC.
