A Lot of money. Flimsy and not well supported By DONALD
I purchased this unit, and external LiFePO4 battery, cables, a special USB cable to analyze this unit's log data, and an inline PowerPole voltmeter. When all connected, I discovered my radio was shutting off at odd times. The unit instructions describe situations like this, like when the vehicle battery runs too high or too low in voltage. So I decided to run the WMRDIAGNOSTICS utility. The section in the manual, by the way, does a terrible job of telling you how to use this utility, how to read the log data, and how to change the default parameters. As an aside to this review, here is how you use the utility:
1) download the WMRDIAGNOSTICS utility
2) install it on a laptop.
3) run a USB micro B cable to the ISOpwr+.
4) run the utility.
5) check the box to save the log data. Then, double-click on the COM port row that lists the ISOpwr+
5) click once inside the black box that appears.
6) press S
Well, after spending a total of $236 for all the things I needed, I finally figured out why my radio is dropping power periodically. It's not that my car hit the High Trip or the Low Trip value; there is a loose connection around the 40 amp fuse holder on the vehicle connector. Jiggle it a bit and the power comes on. Jiggle it more and it cuts out. The fuse is fine. This was a huge disappointment and a big time-sink. :-(
