    "Modbus RTU slave on RS-485. Registers are numbered from 1, as in the document. FC03 and FC04 read, FC06 and FC16 write; the on/off parameters can also be read and written as coils (FC01, FC02, FC05, FC15). The registers are mapped as holding registers here.",
    "Baud rate 9600, 19200, 38400 or 57600 bit/s, 8 data bits, 1 or 2 stop bits, parity off, odd or even (register 123). The document gives no factory default for the address, baud rate or parity; 9600 8N1 and address 1 are assumed here.",
    "Values marked u.e. in the document are whole numbers in engineering units, with the decimal places set in register 63 (1234 with one decimal place is 123.4). Values marked x10 are tenths.",
    "The ramp and soak program segments (registers 250 to 1227), the write-only calibration commands (220 to 227, 232 to 237), the output calibration (238 to 243) and the 16-character tag (registers 126 to 141, one character each) are left out. Several registers are only meaningful when the matching option is fitted.",
