Hi and greeting from Italy. I'm writing this message on behalf of a friend who doesn't understand English. My friend works in a company that own a milling machine powered by a MELDAS 64 ASM controller.
Transferring data from the CAM program in the PC to the CNC controller via RS 232 is a process that is having problems. The data is someway corrupted and the result is obviously a wrong operation.
The RS 232 settings we are using are :
7 data bit 2 stop bits 9600 baud even parity flow control : xon/offThe cable configurations is :
MELDAS 64 ASM PC

We are using Windows Hyperterminal as comm software.
The cable is onlya couple of meters long and so cable length is not an issue. a Technician suggested to use hyperterminal to transfer the Gcode using the same communication data parameters and a VT100 terminal emulation. I'm a computer consultant and after seeing the problem I suspect that the data flow control could be the problem. Another question.... in the hyperterminal configuration options there is a check box labelled "force incoming data to
7bit ASCII". We didn't try this option and I'm wondering if this could solve the problem. Software flow control made via Xon/xoff is not affordable and I think that the parameters data could be wrong.To solve this problem in another way an expansion board for the Meldas 64 ASM capable to support flash cards has been acquired. The part # for this board is FCU6 EP203 (or at least this is the item # quoted in the invoice). The techincian was not able to make the MELDAS 64 ASM recognize this expansion board and so the flash card can't still be used. Which is the correct procedure to let the controller recognize this board ?
Do you have some idea about how to solve this ? Further info about the controller are : Part # FCU6 - MU032 version B with sw BND 39w000 rel. C5.
