Description
DC822 is a LoRa ↔ RS485 converter
The DC822 is used for remote reading and parameter setting of the meter with built-in RS485 communication. Wireless communication enabled by LoRa communication. The module can read up to 32 counters that prophesically sequentially and automatically transmits data to the server. The programmable reading interval of the meter, at least 1 minute, must be greater than the number of counters entered.
Power from the power grid.
The EN 62056-61 Object Identification System (OBIS) is used.
DC822 can be parameterized in two ways: LoRa by calling, or locally via serial bus. Parameters that can be read or parameterized are the serial numbers of the connected meters and the frequency of the module reporting. Module serial numbers, hardware and firmware versions can only be read.
Parameter setting or readout settings are protected by a unique 16-digit cipher for each DC822 module, so settings can only be accessed by authorized persons.
