    "Teltonika TRB140 LTE gateway: the Modbus TCP server and the serial Modbus server both answer with the same system values. The registers are holding registers (function 3 to read, 6 and 16 to write).",
    "The manual lists a register address (0-based, as sent on the bus) and a register number (address + 1). This map uses the address.",
    "Text values take 2 characters per register. Numbers take 2 registers; the manual gives no word order, so big is assumed.",
    "Mobile data counters are in bytes, kilobytes or megabytes, as chosen by the Mobile data type setting of the Modbus server.",
    "The server is off by default. Factory settings: TCP port 502, device ID 1 (0 answers to any ID), serial 9600 baud, 8 data bits, no parity, 1 stop bit.",
    "With 'Enable custom register block' on, registers from 1025 onward are a user-defined block that is not in this map.",
    "Left out because the manual is not clear: Mobile data received last month (SIM1), Mobile data sent last month (SIM1), Mobile data received last week (SIM1), Mobile data sent last week (SIM1), Change APN (length not fixed)."
