We have purchased a used 5 axis mill with a Mitsubishi M540MC controller. We received very little documentation with the machine (mainly hydraulics diagrams only).

I am trying to setup DNC for the machine, and I am really struggling to get a complete set of information of how to proceed. I have searched high and low, and have managed to get bits and pieces of information, but nothing concrete.

Currently I have done the following:

Cable wired up as follows:
15 Pin CNC end - 9 pin PC end
6Tx - 3Rx
7Rx - 2Tx
11Rts - 7Cts
12Cts - 8Rts
1Ground - 5Ground

This cable is connected to CSA21 on our QX521 board.

I am trying to send a simple program using Hyperterminal on a Win XP machine, but I cant get anything to work.

Anyone out there either with this controller or something similar who can help?
