Diagnostic lead

[GTOBEN]

Hi all.
I suspect one of my sensors are playing up on the cerb and need to diagnose the problem. Does anyone have a serial diagnostic lead i can buy, beg borrow or steel? I have looked at the diagram to make one and its all a little Greek to me.

You should beable to buy the cable outta any decent pc shop, there a very common item(well used to be, not so much now i think as i had to order mine online)

its a bog standard serial adaptor lead, Maplins, PC World, Dixons, Staples etc

I "belled" my original 1 metre cable out at the weekend. It's a straight 1 to 1 cable i.e. pin 1 on the MBE to pin 1 on the PC serial port etc. I made up a 4 metre lead at work so you can have the laptop on the bench.

so do you need to include the resistors as shown on the SBD Motorsport diagram?

Do you need the resisters - well that depends.
Most people report a straight serial lead works fine, but a couple of people have said they needed the resistors.

Ok thanks, seems to be getting a bit simpler now.
What sort of cable should i buy?

DB9 Serial Cable - Female connection one end, Male connection the other end.
