Mitsubishi Meldas 300-V

[firestaromega]

So I am trying to hook up a Meldas 300-V to my laptop to run it with Mill9

I have a db25 cable out of the cnc machine into my parallel port. but I can't seem to be able to connect to it. I am pretty familiar with computers but very unfamiliar with cnc hook ups

any help would be appreciated.

thanks

Thats your first problem, using the Parallel port, The transmission uses RS232-c Serial port, go to the Cadem.com site and the cable config, and parameters are there.

ok so I need to get a RS232-c Serial port to parallel converter?

excuse me if I am misunderstanding.
thanks

The serial port on a PC was originally 25pin, now it is 9 pin D, CNC machines traditionally have kept the 25 pin so you need a 25 to 9 pin cable or use gender changer.
I would recommend that you use the 3 wire cable with handshake jumpered out, the pin-out is here or several places on the web, including a good one on the previous link I mentioned.
Google RS232 to get an idea what the protocol is.
If you run into further problems after getting the right cable, pose your questions here.
If you need a communication program there is also one on the link. Do not use Win. Hyperterminal, make sure the Transmission setting are the same for both ends and use software handshaking.
I just though of something, if you have a modern laptop you may not have a 9 pin serial port, only usb, in that case you may have to get a usb to RS232 converter and hope it works.
