G2 Linkplus Aux outputs

Recommended Posts

Help please to correct an inaccurate speedo,  If an auxiliary output is set to speedometer , can it still drive a positive 12v signal to my SD1 rover digital speedo?

I have configured a digital input D1 for speedo with a drive high input, thus to accept a positive 12v inpulse from the 2 wire speed transducer.

Cheers

Snow.

Yep it will be able to do that.

Normally the speedo will have an internal pullup and the ECU switches the ground.

If this isn't the case you can add an external 1K pull up between 12V and the signal.

Thanks Simon,

Just to be sure, is that 12volt supplied resister  hooked to the links output to the speedo?

1985 Rover speedo`s not like the modern electronic`s where all imputs switch to ground.

Cheers.
