    "Modbus RTU on RS-485, FC03 (read) and FC06 and FC16 (write) only. Addresses are 0-based, as sent on the wire. Every register is a holding register, including the input states.",
    "The document gives fixed serial settings of 9600 bit/s, 8 data bits, no parity and 2 stop bits. It gives no slave address; 1 is assumed here.",
    "The linked document is titled DM (Data Acquisition and Control Module) and covers the DM1, DM2 and DM3 versions with 8, 16 or 24 digital inputs (Y1 to Y24). It was requested as DMX.",
    "Input states and the memory buffer are bit fields, one entry per bit. The document leaves the register numbers of the last five rows (firmware version and release, and the three buffer reset commands) blank, so they are not in this map.",
    "The document was written for firmware 3.2. Written from that document; this map has not been tested on a device."
