The connection to the PC is done using a cable which converts the optical signal (IR) on the multimeter to RS232.
See [[Multimeter_ICs#Fortune_Semiconductor_FS9721_LP3]].


The serial connection uses '''2400 baud''' (hardcoded, cannot be changed) with 8n1 settings. The multimeter transmits 14-byte data packets periodically, the host can '''not''' send any commands whatsoever, only read the transmitted data.
