Using TachoPro Cables with Digiprog: DB25 Connector Pinout & Nec Dongle Compatibility

Question

i,m trying to figure out how to use tachopro cables to digiprog, so i mean, tacho pro has the nec dongle included , and as i,ve searched on internet they look the same, the only difference is the db25 pinout connector, so please does anyone has the tachopro db25 connector pinout ? cause for the...

D25 connector to TachoPro has diferrent configuration regardless of what eprom/processor needs to be programmed. It is on main board and there are two CMOS chips connected directly to this db25 called octal buffer/line driver 74HC541D. Depending on what processor/eprom needs to be programmed internal processing unit on tachopro sending diferrent signals to 74HC541D and diferrent pins on db25 actually works (eg diferrent pins works on c66 memory cable than on 9s12 processor cable / dongle). It is about aplication - internal software choosing how to drive db25 to work with specific cable.
I bet to find cable #37 nec dongle schematic to tachopro and take a look on db25 pins.
Hope it helps.

i have 2 #37 cables they are a bit different but not so much, and based on atmega32L pinout the db25 pinout of #37 cable is:
1=nc
2=nc
3=nc
4=reset
5=nc
6=nc
7=tx
8=rx
9=nc
10=nc
11=nc
12=nc
13=nc
14=nc
15=nc
16=nc
17=ss
18=nc
19=nc
20=nc
21=vcc
22=nc
23=nc
24=nc
25=gnd

hope someone know how to connect this adapter to digiprog3

As you see cable 37 has tx/rx pins to be driven by tachopro. Digiprog has them not. It only has Eeprom pins (to direct programming) and Can network output. So in this case some kind of interface is needed to decode signals from digiprog to language of tachopro cable #37. I do not see any way to directly connect both devices.

hi friend, ok can we recruit someone to build this kind of interface adapter between digiprog and tachopro cables? if yes, just tell me what is needed and how much will cost, so we can try out to find that cash

gabik001 · Answer

I think it needs to be built with some kind of interface based on atmega. First of all schematic is needed and main problem is to write software that will transfer languages between those two diferrent programmers. IMHO this is pointless. Better to buy good working tachopro and use it for programming. It will be cheaper and less time consuming.

tacho pro has its car list limitation, and digiprog3 has its own car list limitation, combining those two will be great, anyway i understand it, but i compare the nec dongle of tacho pro and nec dongle which is in sale for digiprog3 , they look the same , same chips and components, it could be only db25 different connection i think

gabik001 · Answer

It might be same aplication for both. But main problem is as I wrote few posts over adapter driver has diferrent way that is controlled by tachopro or digiprog. I mean adapter might have same chip in it but chip might have such diferrent software inside.
I will look in my db I should have tachopro nec dongle schematic. If you will find digiprog nec dongle schematic we can do something.
