Protocol
The connection to the PC is done using a cable which converts the optical signal (IR) on the multimeter to RS232.
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.
A short protocol description is available from Voltcraft/Conrad.
