Hello all. My company has a HAAS TM1P 3 axis milling machine. They will not allow us to use the ethernet interface or the wifi interface due to company policies. My colleges and I are now forced to use a serial RS232 interface. We want to drip feed programs from our laptop directly to the mill using the serial port. We have the serial board and ribbon cable which I will attach pictures. We just do not know where to plug it into on the main HAAS controller board. Or if it is even the correct serial board for our machine. It was the only one we could find and it says it is compatible on the HAAS website. Any help about where to hook the board up to and pictures/diagrams would be greatly appreciated.
