RS232 for fanuc

[bryan.davis]

does anyone know the connections and pinouts for a fanuc DNC cable that is capable of drip feeding, our cables are OK for simple downloading but they cant manage drip feed.

Hi Bryan

First of all, do you use software handshake.

if not, I think this is might be your problem. Because normaly a cable that works with normal transmision will also work with dripfeed, if the handshake is correct. And most Fanucs normally runs with software handshake.

If you want a description of a standard RS232 cable, please go to http://www.dncmax.com support-knowledge database - correct cables.

Most RS232 cables jump out the Handshake signals. The best way to make sure you can DNC (Dripfeed) to a Fanuc control is to make a cable that has all the wires connected at both ends. I sent an e-mail with an attachment showing these pin outs.

Use software handshake.
