Ground while running wire has a constant 12v reading

Question

After installing a Prestige APS787E alarm w/ my Evo-All bypass module on my 2012 Nissan Rogue (Non-Push2Start), my lock, unlock & trunk buttone on the aftermarket keyfob work but the remote start doesn't work. I updated my Evo-All to the latest firmware & hardware available & flashed it to D2D protocol.

I also programmed the Prestige alarm using the install guide to get the Tach signal via D2D mode. But when I attempt to follow the "Tach rate progarmming" section of the manual, it is clear the alarm might not be getting a tach signal.

Is it possible to hardwire the tach signal to my alarm while using data mode w/ the Evo-All?

Secondly, I test the "ground while running" wire connection btw the Evo-all & Prestige alarm with a multimeter and I get a constant 12V even when trying to remote start. Is this normal? I thought it would/should give me a 0V or ground signal when I attempy to remote start the car.

Lastly, also just noticed that my Prestige key fob arms the aftermarket alarm but locking my doors w/ the OEM Nissan keyfob doesn't. Thus when I arm the car w/ the Prestige keyfob & unlock & open the doors w/ my Nissan key, the siren goes off. Is this normal? 

Thanks in advance

Make sure option F2 is enabled in the evo-all. This will allow proper datalink communication between the auto-page unit and the evo-all. If not, datalink will not be 100% functional (such as that tach not working). Similarly, you can just use the wire-to-wire configuration.

This will be normal on this vehicle since there is no way for the Prestige to detect the oem remote commands.

Pink wire on the 20-pin connector is an analog tach signal.

The GWR coming from the remote starter should definitly be a ground signal when the remote starter is activated. Maybe the remote starter is actually not activating? If ignition does not turn on, chances are the remote starter is actually not activating. Might need to contact autopage for this part.

Sorry for the late reply but thanks for this info. You were extremely helpful. The remote start works fine now.
