I have one of the "Chinese" E1938 modules I bought about a month ago. I
just tried it out on the bench, and have not had much luck with it. The
5 Volt supply never goes above 50 mA or so, none of the heaters seem to
be powered looking at the "hockey puck" D-sub connector pins. The four
leds up by the PIC (?) seem to flash once on switch on and then pulse
about once a second. The other led which seems to be on the 5 V supply
is on. It does oscillate, but very low since it never warms up.
Is there any point in my trying to go any further with this? It seems
pretty dead to me, the PIC maybe? :^(
Nice museum piece perhaps, but a bit expensive for only that...
