We have a leadwell with a Mitsubishi Meldas 50 controller and we had a real problem getting the comms working until we found that there are two page settings if I remember correctly. There is a setting page for in and a setting page for out and you have to use a different port for in than out if that makes sense. We use a free comms from Onecnc called nclink and that works fine on ours. It was a hell of a job getting it going until we found that out and I think we emailed them and was told about it. That was a year or more ago and it has worked ever since. Maybe that is some help |
