Fagor wont read from serial port

[PinMan]

I am trying to load programs from a CncGcoder handheld to my Fagor 8055M Mill and I'm not having any luck. After trying all the solutions presented by Fagor Automation, I am turning here for help

When I set up the controller to recieve the program, it waits and then I get the 'End of Attempts' message. I have checked the DNC parameters in the control and on the handheld, they all are matched up correctly. The handheld appears to be sending the program but it is not being recieved by the CNC.

I have also checked the 9pin to 25pin serial connections for any loose or default there. Nothing seems to be wrong with the connections.

I have followed all the guidelines from http://www.fagor-automation.com/CNC/..._232_Setup.pdf unfortunately this is the only help that I have found so far.

Thank you in advance for any assistance I recieve

I take it you have the correct pins jumpered out on the 25 pin, I would suggest the more common jumpers of 4-5 and 6-8-20 on the 25 pin end.
If the unit is bi-directional, does it take an upload from the Fagor to the unit?
The alternative is to either get hold of a break-out box or try a PC portable with a 9 pin serial port and one of the free comm programs.

I did make sure the correct pins where jumpered. It is a bi-directional connection but I am unable to upload from the Fagor.

Update: After a little bit of adjusting to the parameters for the serial port, I was able to get the controller to recognize that the handheld is connected. Unfortunately, I am still unable to load a program into the controller or vise-versa. I have made a little bit of progress though lol.

I had issues with my 8040. It turned out it wouldn't read because my baud rate was too LOW.
The control has settings for the low baud but i couldn't get it to work until i cranked it way up.
The machine manufacturer also had the serial port wired wrong but you said you have checked yours.

Hi:
Fagor automation has a WinDNC application for free, that allows a straight through serial cable from a PC to be used. The program is easy to use, and I had it up and running uploading and downloading from the 8055M in minutes.It also alllows you to backup all of the parameters
Also: The tech support for Fagor is really good here in Ontario, look them up and ask for Mohit, this guy is really sharp.He has walked me through many problems.

Suggesting a straight thru cable means nothing without further clarification.

To be helpful provide information with the exact wiring and pinouts.

Hi: A non cross over serial cable, the kind you would purchase at Best Buy etc.
Pin 1 to 1 etc.

cheers

PS I'm trying to be helpful, so ease up on the "to be helpul comments"

Suggest you go direct from the 9 pin connector at the back of the Controller Module and by pass the 25 pin plug.

Now that you have provided a Fagor circuit diagram there is some useful information.

Since Fagor is using a 9 pin RS232 connector with the same definitions as as a 9 pin PC connector, and since the most likely connector on most moderately new, last 20 years, PCs is a 9 pin connector, then it is not a straight thru cable defined by pin X to pin X. Furthermore, Fagor shows a cable for use with software handshake.

This is why a more complete definition of a cable is important.

I see too many comments like "do this ---- " and you are "good to go." with inadequate supporting evidence of why.

The reason for my suggestion was my controller had a 25 pin connection on the front which was installed by the mill manufacturer but not as Fagors recommendations.

My Fagor 8055M is wired as per the illustration on the web site link on post #8 by Cam1.

I connect to mine using a "handshake cable". If I remember correctly it is because Mohit (Fagor) provided the electrical connection defining such.
This same cable also works my 94 Fadal and my 81 Sodick.

Kiwi and I share the same experience. My machine had a 25 pin connector attached to Fagor's 9 Pin. The 25 pin WAS wired wrong. I rewired it and I have used the 25 pin with no issues.

I use Fagor's version of WinDNC and I had to set the baud rate very high or comm would not work.

Theoretically I could use a "straight through" cable if I rewired the machine builders "scab" cable into a crossover configuration.
