When a pin goes high it is at +5V (well it should, but some systems
don't make the full swing), but there is not enough current from the pin
for more than one LED. G201s are wired to use a common +5V and switch on
the LED in the opto when the pin goes low and current flows to it.
G210's can be set up to use the current from the pin with a common
ground.
