Suggested limits. A person must confirm every limit before this device can be written.
Eastron ships the meter at Modbus address 1 and 9600 baud. This file expects address 2, so it can share an
RS-485 bus with the SDM120 file at address 1. Set the address in the meter's setup menu, or change unit
and match.modbus_id to 1. Registers are the zero-based input register offsets from Eastron's protocol
document, as IEEE 754 floats. This file only reads.
