My shop has an older Okuma LNC-8 CNC lathe. currently we are having to input programs from the control letter by letter. the machine has the ability of using RS232 for DNC, but i am having trouble getting it to work. I have the Okuma DNC setup page and have the cables with the proper pinout and the settings on my computer and the machine are set to the specified settings, but i cannot get data to transfer to the machine from my computer and when i get data from the machine back to my computer it comes back all garbled. any time i try to send data to the machine i either get the following errors.
2505 tape parity ERROR 4F or 2505 tape parit ERROR 25. i don't know what those error codes mean. i have the error code book for the lather but it doesn't tell me what the 4F or 25 part of the error means. any thoughts?
