Enstone should be qualifying in the top 10 on the grid
Stack ST857 & Magneti Marelli DL cable MT1005

Hello,

I'm a new member on this forum and I have few technical questions regarding specific data acquisition system.
Trough the different posts I've read here, I think I could find somebody who could help me.
I'm working on 2 cars for Hill Climb, one osella 3L bmw and F399 Dallara.
On this osella we have a dashboard Stack ST8100 and I want to fit an HR800 data acquisition system (ST857). Ok it's a little bit old, but for the moment I will be ok for us. I can't found the Data Pro software to download and set-up the system. Maybe somebody on the forum has an old version of this software ?

My other question is about a magneti marelli MT930 data acquisition system which is fitted on F399 Dallara. We are missing the download cable MT1005 (centronic connector)! I can't find a 2nd hand cable (and MM doesn't want build new cable, they only want sell me a 4000 € new data acquisition system). If somebody on the forum could give me some indication to find a 2nd hand cable, it will be really helpfull !
The other way is to build my own cable. But it’s not a direct cable link; there is control board within the cable so I can’t build my own cable for the moment. And then I’m looking for a kind person who will agree to carefully open his parallel connector and take some pictures & made some wiring draft?
Maybe there is electronic specialist on the forum and somebody could help me to build my own cable.
I know the MT930 have 4 outputs to communicate with computer:
=> Rx (receipting data);
=> Tx (transmitting data);
=> Clk : clock (synchronization)
=> Ground
And as the DL cable is fitted on parallel port, I asked my if the transmission is done with a CAN protocol (if yes I will be completely lost , but I think the Centronic connector is too small to fit all electronic component for CAN protocol). If the transmission is done with a parallel way on the port (data on 4 / 8 bytes on pin 2 to 9 of the parallel port) I need an IC such 74HC595 or any else UART to convert serial transmission (Tx or Rx from MT930) to the computer. The last solution of transmission could maybe made trough RS232 protocol (Tx,Rx,Ground).What do you think about it?

Anayway, many thanks for all your kind help & answer!

Bye
