Linking Inventor HSM to Bridgeport

[AndrewMawson]

Program format is absolutely vital - other wise it's ignored - here is an example pasted - don't seem to be able to attach as file :(

You have read the bit about setting the TNC 'mode' haven't you re EXT FE etc - sounds like your cable or setting are wrong rather than the pogram though

Yeah i think it sounds like the cable, i've been told pin layout will be different on the one i have... So ive just been to maplins for the bits to make up a new one :).

The programme the cam has generated looks absolutely fine.

Cheers,

Wired cable up 2-2, 3-3, 5-7 and still no joy. Will try with 4-8 6-4 7-5 and 20-6 aswell and see how we get on (wiring from post on cnczone).

Cheers,

There is a Heidenhain publication called

Data Interfaces
of HEIDENHAIN Devices
Service Manual

Google it and down load - if you can't find it pm me your email address and I'll send you a copy.

It describes all the parameters and setting for the various controllers for RS232 comms - this is a small extract that is probably in your manual anyway but it has far more detail

[jackpat]

Andrew,

How funny, i started looking through the interfaces manual just as you posted. Hopefully i will have some joy with it...

Cheers,

Jack

Hi Andrew,

Managed to get back to the bridgeport today, i rang heidenhain for pinouts so cable is sorted. TNC server and controller coming up with no errors, however i can only send a programme to the laptop from the controller! Which is the opposite of what im trying to do. Whenever i try to send the opposite way, TNC server just says "receiving file" for a couple of seconds then goes back to doing nothing.

Any ideas?

Cheers,

Jack

The format is crucial. I seem to remember that it has to start with CR/LF then the file name etc, but it's all described in the link I gave you. (As were the pin outs !!!!) Check what mode you are in by pressing the MOD key as per the manual - is it FE mode - I can't remember it's been a long time!

Does your TNC145 allow you to do a Directory list of available programs off the PC, and if so is the one you want showing?


.... hang on ... TNC Server says 'receiving file' ..... it should be SENDING a file - something wrong there how are you intigating the transfer - it should be done on the buttons on the TNC

In edit mode, press 'Program Number' then EXT and on the menu displayed select 'receive selected program' - press the number corresponding to the program and Enter and it should come whizzing in and show on th PC screen TNCServer panel as it does if you have the 'detail' option pressed.


Got your baud rates set the same both ends and iirc TNC145 can only do 1200 baud ??
