Protocol
See Multimeter_ICs#Cyrustek ES51978 for the DMM IC protocol.
The transmission of the measurement data is disabled by default. The respective Cyrustek ES51978 pin (45, RS232) is hooked to an IR phototransitor so an IR LED has to be turned on in front of it to enable RS232 output. Pressing any button on any TV remote in front of it is enough to turn on the measurement transmission.
