120ohm terminating resistor should be placed across the CANH

Hi,

Got a Can Bus PCB designed and protoyped, we used a Freemantics MkI Emulator to test the comms, ( and yes its not takling correctly ) the question is quite simple does the Freematics Mk1 emulate or have a 120ohm terminating resistor as would a car across H and L.

Or is this not needed when testing with the V1 Emulator ? it seems it is not needed when used with a car.

We just ordered the Emulator Mk2 to see if there is a difference

Anybody have any ideas ?
