DB9 on EQ6's much easier to get right. Mind you, I KNEW I should have had glasses back then
Thanks Rob.

Meant to say also splicing a network cable with TTL possibly safer if you're struggling with pinouts for the RJ45. The other issue I had was eventually my outer covering pulled out of the RJ45 socket, whereas the sealed "all in one" commerical network cables generally have "industrial strength" socket fittings - one more reason to consider splicing for HEQ5 cable.

Also another reason to suspect I didn't have skills to be making the RJ45 crimp in first place ("how hard could it be", I have a friend that says!?)

Here is the pin diagram of RJ45 and RS232.


Pin 1 of RJ45 connected to Pin 5 of RS232
Pin 4 ..............................Pin 5 ..
Pin 5 ... ... .. .................. Pin 9 ..
Pin 6 ..............................Pin 6 ..
Pin 7 ..............................Pin 1 ..
Pin 8 ..............................Pin 8 ..

It looks like pin 4 of RJ45 was connected to Pin 5 of rs232, but I am not sure. Can some tell me where should I connect or is there any easy diagram which shows connections between these two connector.

Thanks
Arif
Figured out the problem, Pin 4 of RJ45 was connected to Pin 5 of RS232. Tested yesterday and working ok.
