best option for SOC for RXV ?

Hey Bob what's your take on this RXV SOC meter? http://www.ebay.com/itm/EZGO-RXV-Dig....c100290.m3507

Well, it's not an Ezgo part, so it's not good idea to plug it into the cart harness. That means running wires. As far as it's performance, never tried one myself.

Your right it's not saying plug and play. Not for me unless it is. Thanks cgtech.

I don't see the harness interface shown, and would not trust such a meter not knowing how it would interface to the controller. The controller is the smarts of the E-Z-GO SOC meter, and like cgtech, I would be concerned with anything aftermarket connected to its SOC 5V digital I/O port without knowing how that device interfaces. What complicates matters is, there are several "standards" for logic levels... The original 5V/0V, and several newer voltage points that are lower for more modern digital devices. This can be anything from 3.3V/0V down to 1.6V/0V. A 5V/0V logic interface will not function reliably with a device that has a logic level lower than 2.6V/0V

Thanks Bob.

I found this after my neighbor has already ordered the OEM one...

That's interesting. Still a little shady about non Ezgo stuff on that plug, but it does look pretty cool.

That's the same one another member here showed 3 days ago. I would not recommend it because there are no digital specs given. You can really only use a SOC meter with a 5V/0V logic level I/O state on an RXV. More modern digtal devices can have logic I/O states as low as 1.6V/0V and the Curtis controller, as a legacy digital device, will not reliably recognize a logic state of less than 2.6V as a logic 1 on it's SOC I/O port. Let's just say that not all microprocessor chips communicate at the same voltage level. The newer they are, the lower the voltage they use tends to be. Not many use a voltage level converter to keep them compatible with legacy digital devices. I hope this is not too confusing.

If enough people are interested, I would be willing to test one to see if it is compatible, after I get back from DC.

I'm interested Bob.

I did not check the sellers but the difference I saw and the only reason I posted the new link was the "plug & Play" pigtail...
