Protocol

See Multimeter_ICs#Cyrustek ES51922 for the DMM IC protocol.

Depending on the cable, additional decoding is needed, though.

TODO: Serial cable vs. the two USB HID based cables.

The transmission of the measurement data cannot be disabled, the respective Cyrustek ES51922 pin (111, RS232) is tied to GND (i.e. transmission is always enabled) on this multimeter.[1]
