The meter is a single-phase RS-485 device: the factory serial settings are slave address 1, 19200 bps, even parity, 8 data bits, 1 stop bit, which are the settings the gateway must use. Measurements are IEEE 754 single precision in kW/kVAr/kVA; the energy counters exist twice, as 64-bit integers in Wh/VARh at 3205-3257 and 4197-4241 (not listed, because this format has no 64-bit integer type) and as Float32 values in Wh/VARh from 45101, which are listed here. The command interface at 5251-5377 and the display and communication settings are listed as far as they are documented in the same table; the tariff command (2008) and the diagnostics block (20004) are listed with their documented values."
