Firsly, thanks for your reply. After messing withthe machine all day, I found that it will run in DNC, but at only 300 baud. It's been a long time since I milled Aluminium at 15"/min. The part should be finished by this time next month!!
To answer your question(s), I am able to upload and download programs at 9600 baud in Edit mode - no problem. I was using a PC that only had a DB9 serial connection, but I changed to another PC that has a 25 pin serial, hoping that might be the answer. The cable is connected with the 2's and 3's crossed, the 4's and 5's crossed, 6,8 and 20 tied together, and the 7's straight through. The software is set for Software Handshake, 7, even and 2. I have checked, and double checked all settings, parameters and connections - but I must be missing something.
To enable DNC on the control, aside from the parameter changes, is it enough to just choose the "Tape" key, and press start? Or could I reconfigure to use M198PO????L? in Memory mode?
Also, on board Base 1, position CA34, there is a PMC(?) cassette attached. What the hell is it? The machine has a tape reader as well. The tape reader is attached to position CD4B on the Base O board, along with the RS232 on position CD4A. Should I disable any of these?
Surely, this thing must be able to DNC faster than 300 baud. I also have a Mazak AJV that is older than this Niigata, and it will DNC at 4800.
Again, thanks for your reply.
