Zvei Probe

Optical probe for connecting PCs and PDAs to electricity and gas tariff meters


ZVEI – IEC 61107 (IEC 62056-21) optical probe is an interface used to connect PCs and PDAs to electricity and gas tariff meters, with galvanically insulated connection.

It allows the bidirectional communication between the two devices, transmitting with an infrared led and receiving with a phototransistor; the device power supply is provided directly via PC serial / USB interface. A special circuitry allows to limit the current absorption to few mA, granting a perfect operation with any RS232 serial port or USB port.

To simplify the implementation of the communication software, echo suppression is electronically ensured in reception. Echo would be otherwise present due to optical reflections. On request, it is available a version of the product that electronically ensures the presence of the echo of transmitted signal.

The magnet used in the device is a “rare earth elements” type, in order to ensure a better fit to the meter than a traditional ferrite magnet (F > 15N).

The serial probe can be equipped with a SUB-D 9 male pin connector for PDA connections (DCE), or with a SUB-D 9 female pin connector for PC connections (DTE).
The USB probe is equipped with a USB type A connector. It is USB 1.1 and 2.0 full speed compatible. In www.teamware.it are available Windows XP/Vista/7 drivers: drivers for other operating systems can be found on the web page of the chip producer.

The Zvei probe is manufactured in full compliance with IEC 61107 (IEC 62056-21) standards.
