In the following drawing example I have a CANBUS that is terminated on both ends with a 120ohm resistor giving the final ohm reading of 60ohms across the two lines. I want to connect the instrument cluster that also has a 120ohm resistor inside it. This will essentially mean instead of there being two 120ohm resistors in parallel, technically there will now be 3 120 ohm resistors. What ohm value will that give across the two lines? I need the ohm reading across the two lines to remain at 60 ohms. Any ideas how I can do this?
Thanks.
Thanks.
