I have a 1996 VF-2 that will not send programs back to the computer. It was that way since the day I got it about 5 years ago. I would like to get this fixed and I want to know what board the RS-232 function is on.
It receives programs fine, but when you attempt to send, it beeps but nothing gets sent or maybe a few characters. To save a program I have to send it to the floppy drive and take it to the computer by hand.
Can someone tell me please?
Thanks in advance----Mike

Why are you sending me to a BobCad site to fund out what board it is on, they know nothing about Haas electronics. I have been running Haas mills for thirty years, I know how to hook them up and do all of my own repairs, have not seen a Haas tech since about 1998. What BOARD is the RS-232 electronics on?
Thanks---Mike

There is no need to be rude, I would have thought someone with your apparent experience would be fully aware of what board the RS232 is on!
Before blaming the machine make sure your RS232 setting are the same on both the machine and whatever your using to send and receive programs.
If everything is ok and you do suspect a faulty board it's on the other side of the connector you plug into on the electrical cabinet. A machine of that vintage should have 2, try swopping the boards around.

Obviously, based on the answers I am receiving, I am unable to properly explain the problem. So please disregard this thread, since I am not able to delete it.

If you think the problem is on the hardware side, look for an RS-232 driver (or driver/receiver) chip. In the equipment of that vintage, it could be something like MC1488 (also known as SN75188).
...So much for the easy fix if all the Parameters are set correctly. Looks like the RS232 chip is on the main board. Here is link to someone with VF-3 that might be what you are looking for.
