ECM-1220, ECM-1220.H or EML-2020 Support
Some issues have been resolved in the latest firmware
version. This also includes many new features.
It is strongly recommended to upgrade your firmware
(free of course). This consists of connecting your Energy Consumption
Monitor to a computer and re-flashing (re-programming) the firmware. The
firmware is the internal program that runs your energy monitor.
If you did not purchase the software package with your
unit, you may not have the required data cable to do this. You will need
to acquire a "USB type A, Male-to-Male" cable. You will also
require the USB drivers downloadable from the same page as that for the
firmware upgrade:
