We see there is a jumper for EXT and NET in the EL037. Is EXT for an external power supply to the EL037 while the NET is the setting for the EL037 to draw its supply from the Enviromon Network?
We have a sensor that needs to be supplied with power. Looking at the EMW PDF manual (R5.06) on page 28, we see the connections for such a setup (middle diagram).
Just to clarify, is the 'Power' connector an input that goes into the EL037? Or is it an output that goes to the sensor? If it is the latter, where does the power come from? Is it used with the EXT jumper setting mentioned above?
Lastly, we understand the EL005 has a backup internal battery. What happens if power is not restored until after the internal battery is flat? Would data acquired so far still be stored? In short, is the memory on the data logger non-volatile?
