    "The Modbus protocol is optional. Modbus RTU or ASCII on RS-232 (F300 = 4 or 5) or RS-485 (F315), and Modbus TCP or RTU over TCP on the LD1050 LCD network board (F300 = 11 or 12). FC03 only. Addresses are 0-based, as sent on the wire; the manual's InduSoft example numbers them from 1 (84 for 0x53).",
    "Factory serial settings: 9600 bit/s, 8 data bits, no parity, 1 stop bit (F301/F304, F308, F309). The address (F302) is 1 to 255; the manual gives no default.",
    "32-bit values are sent low word first: the manual's example frames read 500 as 01 F4 00 00 and 0.5 as 00 00 3F 00.",
    "The manual is written for the LD2051 and gives the same Modbus registers for the LD1050 LCD. Written from the manual; this map has not been tested on a device."
