I have a big problem with a Denford Zeroturn from 1988 and Fanuc OT.
I want to upload my g-codes by the serial port.
The upload works and the pragram can be run, but not all characters are accepted.

Accepted Denied
A C
B E
D F
G I
H J
K L
M O
N Q
P R
S T
U W
V X
Y
Z

- :
:
,

0 1
3 2
5 4
6 7
9 8

As a result I have this. This code is one that woks:
%
S0500;
M03;
G00;
Z010.0000;
%

But if I change the G00 to G01 ...
%
S0500;
M03;
G01;
Z010.0000;
%
... I don't get an error, but Fanuc show me just "G0" ...
%
S0500;
M03;
G0;
Z010.0000;
%
... the "1" is missing. This happens with all denied numbers.
S0400; results in --> S000;
But if I send just "G0" or "G1" I get en error #002(odd number), so I assume that the missing number is actually send and checked, but then somehow missing.

The characters result in an error 004. I can't make a tool change.
T03 gives me an error. In MDI everything works.

Had somebody a problem like this???
Thanks for your Help

Sounds like it may be dropping characters. What is your baud rate set to? How long is your cable? Have you tried sending a program from the CNC to the PC?

[Miguel_07]

I thought the same, but the transfer seems stable, because there are really just this specific characters missing. I tried with 2400 and 4800, with 1 and 2 stop bits. The result is exactly the same. The cable is self made just 20cm. I assume that the Bytes are received from the machine, because if a byte is missing, the machine would give me the error 002 (odd number).

Check prm #2 bit 3 (if I/O = 0) or prm #12 bit 3 (if I/O = 1) I believe that selects ISO vs EIA/ASCII on input. Just a shot in the dark.

Thank for your help. I played with your parameters and pram 50 and 51. Actually I don't know what I've done, the numbers are working now, but I have now a new Error.
I get the error 11.
If I send Z123.4567;
I get in the machine Z123.4567 ; ;
and the error 11
How can I get rid of it???

delete ";" you don't need it

All the characters that you say the Fanuc does not accept require a parity bit in channel 8. The other characters do not require the parity bit. If your DNC software is sending ASCII with NO parity, that would explain it.

Be sure that your DNC software is configured to send 7 data bits and EVEN parity.
