Gentlemen,
I am working with two Bavelloni CNC stone working machines equipped with NUM controllers. All are connected directly to a PC via Null modem serial cables RS232, one at 200' and the other at 50'. We recently upgraded our engineering room to an XP PC up from 2000 Pro and now we are having communication problems. I have toyed with and even turned off the FIFO buffer as per the manufacturers suggestions to know avail. Initially, a program would attempt to send, and stop, displaying a message on the NC " program exists do you wish to overwrite" to which I would key yes and then the program would continue sending. No matter, the end result would still be a serial line error being displayed or a program 0 ( not the number I sent) being displayed with nothing in it but a jarbled mess. After toying with the FIFO ( and then turinging it off) I can now get the machine(s) to recieve the programs in one continuous shot however, the result is still the same(serial line error or jumbled mess in "0")....If I reconnect the machines to the older computer ( switching nothing but the cables between PC's) the programs sends fine with no errors. All settings in the transfer software on the two machines is identical. The only two differences between the two PC's is that the older one has two serial ports that are wired directly to the motherboard ( OEM) and has windows 2000. The new one possess PCI card serial ports (both on the same card) and runs XP.....PLEASE HELP....the older machine is dying and I need to keep my engineering room rolling at full steam!!!!!!!!!
your friend in technology,
Jimbo
