What other types of optical probe are there?

ABACUS ELECTRICS – IEC – What is it all about ?

The meter and hand-held unit negotiate various parameters such as the maximum frame length during transmission and reception, whether multiple frames can be sent without acknowledging individual frames windowingthe fastest communication rate that they can both manage only in case of mode E switching to HDLC etc. Entitled users will be able to obtain software from the meter manufacturer or from vendors protoco, meter reading systems.

Sorry, Ivan, Pdotocol am Ivan as well. The mode being used by the tariff device is indicated by the baud rate identification character in the identification message from the tariff device.

Remember me on this computer. Australian Standard AS Choosing IC with EN signal 2. Is it same with You must be a Control. Or of course it also means the rx side is fried.

The electricity meter to the right is typical and shows the circular retainer of the IEC port. The protocol is usually half-duplex. To communicate with a particular meter will require more specific data about a given manufaturers meter and possibly a password.


Note that common words and, that, etc. Hi Robert, I connected oscilloscope to the receive side of the sensor. Please read those terms and conditions carefully. The software specification includes data rates, character format and transmission protocol. The mode can be negotiated by the HHU and the meter. Can an IrDA port on a computer be used for reading tariff meters?

It is one part of the identification of the object. Fortune People who understand context would be steamed to have someone else dictating how they can call it. Search for the current document: Losses in inductor of a boost converter 9. Synthesized protodol, Part 2: An IEC probe fits over the port on the meter and shields the meter sensor from stray light.

IEC1107 Electricity Meter Interface

Communication in mode D is uni-directional. I am also interested in data transmision via the electric distribution network Powerline communication. I was thinking of using lirc to test the RX side of the probe. Even manufacturers continue to claim proticol be IEC compliant.

The IEC standard has been adopted by meter manufacturers throughout Europe and in some other territories. Special baud rate – as desired. For local use, National replacement code can be used.
