Optical probe for connecting PCs and PDAs to electricity and gas tariff meters
ZVEI–CEI EN 62056-21 (previous IEC 61107) 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 by an infrared led and receiving by 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.
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 USB probe can be equipped with a USB type A connector or with a USB type C connector. It is USB 1.1 and 2.0 full speed compatible. In the “Download area” of this website, Windows 7/10 drivers are available: drivers for other operating systems can be found on the web page of the chip producer (FTDI – www.ftdichip.com/FTDrivers.htm).
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 Zvei probe is manufactured in full compliance with CEI EN 62056-21 (previous IEC 61107) standard.
