The FIFO buffers definitely needs to be disabled. That could be your problem all along. Predator Software has functionality to deal with the transmission rates of the data. It can put a slight delay...

If the PC stops half way thru, it's probably because the machine is telling it to stop because its buffer is full and you have not run anything. Doing it in DNC mode, does the machine actually start...

Have you ever gotten DNC to work with this control at all? Does loading into memory work?

What is your procedure when trying to DNC? Typically you put the control in TAPE or DNC mode, press Cycle...

You say "unlimited number of simultaneous communications with CNC's", how do you get around the operating system limitation of 256 COM ports?

If you break your program up into small chunks to get it into the memory, you can test the programming of the program itself. Yes, it's going to require putting multiple chunks of the program into...

If you're using a built in COM port on your PC, go into device manager under COM 2 and disable the FIFO buffers.

No one can sit here and tell you if you have that capability on your specific control or not. From my understanding, it's typically an option that is sold with the machine by the manufacturer. I have...

Is that just the end of the program?

that is what came out of the machine, right?

Has anyone played with the command line triggers for the TNCserver?

Can you post the first few lines of your program? and the last couple lines?

Double check your communication parameters on the machine.. Do you have the manual?

Try slowing the baud rate

The term "DNC" is usually thrown around loosely. a DNC program can be used to send programs into memory or to dripfeed into the machine. I am not sure if the freebees will drip, but I do know...

Well, You should be able to push the following softkeys
to read into the control, select READ > EXEC or you can try READ, Type the 4 digit program number, O1234, then EXEC. This will ready the...

Generally speaking, you'll put the machine in a DNC or TAPE mode, hit cycle start, then send the program from the PC. Assuming the communication parameters are set correctly and your cable is set up...

Manually typing the O number at the control before you press Read > Exec only overrides the format at the beginning of the program. Typing in the O number is a work around if you do not have the...

There is a small group of the 5000 line that requires a very special, abnormal pinout on the serial port. There is no way knowing until a professional who knows about this little quirk gets on the...

Put an RS232 breakout box (inline cable tester with LED's) on the machine side of the cable and send a program from the PC. You should see activity on RD. If you do, then it's something at the...

Has it ever worked in the past?

Those controls can sometimes be a little painful to get working. First thing is make sure you can get a program out of the control first. Rename the O number and send it right back in and see what...

If you had Fadals, the answer is yes. But you dont.

Just like mazaholic suggested, a DNC program will allow you to remotely call programs right from the machines, multiple machines all at the same...

Isn't TNCremoNT a network based communication application? Meaning, Ethernet, not RS232? My experience with those specific controls is a bit limited but I have run into them in the field in the past....

I have seen some of those "not so common" controls having a different pinout then your standard null modem cable. Something is telling me that Fagor MIGHT be one of those odd ball scenerios. Dynapath...

the google keyword should be null modem diagram db9 db25.

Are you trying to load the program into the memory of the control? What communication software are you using?

Are you a reseller or consultant?

Greco is outdated and I would be surprised if you find any support. Not sure about Enet. I have seen Predator in many shops, especially in Texas. Many of them run wireless and I havent heard many...
