Fadal CNC 88

[toolman1]

I cant send files to fadal I am using 9 pin to 25 wired (2 to 2) (3 to 3) (5 to 7) I do cold start CD,5 enter TA,1 enter and still will not send text file, we done a test plug on 1030 board and it comes back good we are lost would appreciate some help.

I have never been able to get my machine to COM when setting baud rate on the command line (CD5).
Go into parameters (SETP).
Set and save your desired baud rate.
Turn the main power off to the machine.
Wait 10 seconds
Turn on again
Do CS
Send text file using TA,1,1 or spacebar - 8 - 1

HTH

We had jumper issues on the cable itself...call Fadal tech and they will guide you through it.

Thanks DareBee I tried it without cd,5 and made sure it was set as default, but when I type TA,1,1 and enter it still will not transfer files. I Thank you all for trying to help me but i think I may have a problem with 1030 board even though the test shows to be good someone from fadal said that test isnt always truthful.

[DareBee]

You still need to go into the SetP and set the machine to the correct baud rate EXACTLY as I described above.
Your send software also has to match and send protocol settings must be correct.

Darebee,
My settings on my computer are same as fadal buad rate,data bits 7,parity even,stop bits 1,xonxoff, when I do cold start and then TA,1,1 and enter it still will not transfer, it dont even show that its communicating in my software on PC I have the same setup with my Haas vf3 and when I prepare the cnc to recieve then on my pc software I get % signs rolling on screen which tells me they are communicating I dont get nothing with Fadal.

Have you checked the voltage from the PC.

Between pins 3 and 7 you should have 8-10 volts DC when trying to send a program.

Unplug your cable from the back of your Fadal and check this voltage.

If it is low then check it at the back of PC.

If it is low and then serial card in the PC is bad. Try another PC to verfiy.

My SETP is set for 9600, but the darned thing will *NOT* communicate unless I do a CD,8 from the control.

With the CD,8 it is fine, but for the life of me I can't get it to work by itself on power up. It's only a minor inconvenience to keep having to CD,8 before a PU, TA, or DNC.... But if there is something I am missing, I'm all ears!

Tips fellas ?

[DareBee]

Tips - sure.
I have no trouble running 31,400 (is that the right number?) baud on my '94 machine.
Crank up the speeed.

[Shizzlemah]

Thanks DareBee, I was more wondering about tips on how to not have to always specify CD,8 before a TA,PU, or DNC command :-)

The cable here is like 9 miles long, and 9600 is adequate for DNC.

Interestingly enough, when a program has a "SPRINT" command, it send to the PC without trouble - even without a CD,8 to get started. Hmn...



Edit to add :
Got it!
And it had NOTHING to do with operator error. NOTHING !!!! *lol*

AndyB:

With relatively standard text being sent and while it is being sent you should see a fluctuating DC voltage in the range of +/-1 V from TxD (the RS-232 transmit line) relative to common. In AC position on the voltmeter the voltage reading will be maybe 5 to 12 V while transmitting and 0 at rest.

When at rest, no data being transmitted, the TxD line should be about -5 to -12 V DC depending upon the driver and load.

At the PC 9 pin connector pin 3 is TxD and this goes to RxD at the CNC which is pin 3 on the 25 pin connector. Pin 5 at the PC, and pin 7 at the CNC are the commons. Pin 1 at the CNC is cable shield.


Shizzlemah:

With our I232 Isolator System you can run at anything up to 115.2 kbaud with any reasonable length. Generally to 4000 ft.

I can not help on the Fadal procedures for communication. However, Edster may be able to help.

AndyB,

I checked the voltage on pin 3 and 7 after I type the command TA,1,1 and I just have around 5 volts dc.




Thanks,Toolman1
