HELP!! Heidenhain PC interface Problems

[servocontroller]

I have been working on interfacing my TNC for more than a month.

I am new to heidenhain so please don't mind if i go wrong.

1. using "ext" mode and cable with wiring shown:

<DB9>(PC)-------------------<DB25>(TNC 155)

2 <---------------------- > 2
3 <----------------------> 3
5 <----------------------> 7
1,4,6 looped ------------------8,20,6 looped
7,8 looped-------------------4,5 looped

and using a DNC software I can receive any G code(already present) from my TNC at my PC but i am unable to send my G codes blockwise to the TNC.I have attached the G codes i received from my TNC. A point to be noted is there is no end of block "*" and no file type of it.
at the end of received G codes this * is visible on the machine.

2. I downloaded TNCremo for win98 and when i run it in win98 it gives error before the setup begins i.e "The specified service already exists".

3. According to the discussion going on the forum i tried to connect the machine in FE mode using Pro NC evaluation version (as i failed with TNCremo)and the wiring diagram given by "awemawson" but again no response.
It gives error the "End of Block missing".


when i use MP223 = 1 p
I am unable even to connect in "ext" mode.

4. what are the parameters required for using G codes and transfer blockwise.

we use a null modem

try this http://www.loop-back.com/null-mod.html

if the TNC>PC works but not PC>TNC, the comm is working, but there is a setup problem with the file. find the place for ascii setup in you program.

Attached is a tech bulletin from Bridgeport for TNC communication. And a cheat sheet for using PROCOMM with a TNC2500, and a DOS program used with an old RAdio Shack TRS-80 Model 100.
