Problems when sending .min files back to osp5000 control - it misses random chars.

[nikolaiownz]

Hey

I got a problem with my DNC - i use cimco and i have no problem sending from the okuma to the pc but when i want to send them back there will be missing some chars.. it seems random and not very easy to locate.

here is an example of the program on the pc and what it looks like when its on the control again.


PC Program that i send to the Okuma(it was made on the okuma and send to the pc for backup)

The rest text is what's missing - i see no pattern..

Add a small delay on Cimco. There is a setting for it after each block, like 1-2ms. This is a typical handshake problem, especially on early 5000s. The 5000 LGs or Mg's got better.

[deadlykitten]

hi, i have no experience with cimco, but maybe you should use a shorter buffer and a greater time window ?

i don't know how relevant it is, but there may be something hitting arround 255 chars; check attached / kindly

[OkumaWiz]

Like under the tire says, xon/xoff is not functioning or CTS/RTS is not connected so that when the Okuma says pause while I store data, the PC keeps transmitting thus characters get lost.

Tryed this with no luck.. still missing chars.. tryed removing spaces aswell without luck.

I dont even know what that means

[nikolaiownz]

And its strage with the program name - it will transfer with the correct file name the first time, after that all the transfers will be put in A.MIN program.

[kurmay]

A.MIN is default filename of OSP unit

[underthetire]

Are you sure the word length is correct? (7 or 8)
And what handshake are you using? Early controls like hardwire

Word length? On the program name?

I use hardware

Yep I know. It's just strange that first time it uses the name in the file and next time I send it doesn't. Even though it's exactly the same program. Doesn't ask to overwrite or anything.

If you are using hardware handshaking, is your PC set up to do it as well? File name loss could also be related to that.

typical pattern:

READ
See $ to %
STOP
CREATE FILE
START
READ 256 CHARCTERS
STOP
STORE CHARACTERS
START
READ 256 CHARCTERS
STOP
STORE CHARACTERS
START
READ 256 CHARCTERS
STOP
STORE CHARACTERS
START

REPEAT UNTIL %
STOP
STORE AND CLOSE FILE

IF No hardware handshaking, PC keeps transmitting during STOP and STORE and I guarantee data will be lost.
Same holds true for software handshaking with Xon/Xoff.

Best regards,

[underthetire]

No, it's with parity stop bits, etc. 7 or 8 is the two options.

Okay there might be something into that.

Deadly kitten says that there is something every 256 char op on the post.

I use hardware on the pc if I don't it's not receiving anything at all.

hy nikolaiownz, i really have no clue about cimco, but please look into those 7&8 bits like underthetire said, and also look over xon/xoff like mr Wizard said ... those guys know what they are saying

i am not sure, but maybe you can use a floppy emulator ? please check this out :

some people are replacing the floppy drives with Floppy to USB conversions. They have USB ports and they show up as multiple FD drives of 1.4Mb each so then it becomes possible to run more than even 1 floppy can hold. I think as much as 99 floppy drives can be accessed from 1 usb. You can find them on ebay for about 10 times less than you can get them from your dealer

No floppy to emulate on a 5000 early 5000 were still tape to load osp software and a little later they were huge 8" floppies.

Have you tried adjusting the baud rate? I've seen where some of the 5000 controls will pick up wierd glitches at certain baud rates. Bumping the rate up or down a bit might clear this up.

Like I sayd I tried but it not sending at all with any other rates. Just get an error
