The ABACUS ELECTRICS IEC optical probes are bi-directional interface devices utilising infra-red light. Connecting to the serial port of a computer or hand-held terminal they permit galvanically isolated communication with utility tariff meters as specified in European Standard IEC 62056-21:2002.
Probes are available for use with lap-top or desk-top computers, and also for use with a variety of the hand-held computers commonly used for field data collection.
