Hello,
I am in a bind. I bought a used Mighty Comet, with a Mitsubishi Meldas M3/L3 Control on it and have some questions about how to interface the RS232. I thought one of the guys told me it uses a NULL Modem cable, but I'm not sure of the proper settings. I have the manuals, however, they remind me of reading the OKUMA Lathe manuals I had to read thru 20 years ago, and they are not well written.

I'm hoping some of the better minds here can help me out and have me making some chips soon.

My questions are the following:
1) Null or Data cable?
2) Settings? i.e. Parity? Baud Rate? Stop Bits? Hardware/Software Control? ect.
3) I've read forums where you had to set the PC Terminal's settings differently than the CNC Control settings. True or False?

Anyone in Michigan who has one of these machines or controllers, I would love to visit the shop or pay to have someone come to mine for a little tutelage.

Thanks in advance,
Rob, Mi

PS-One final question, I have the original books that came with the machine, but they say M500 not M3. Any particular reason for that?
