    "Addresses are the hexadecimal ones from the manual (0x9C40 = 40000); the manual's read example sends 0x9C40 as the start address, so they are used as they are (address_base 0).",
    "Function 0x03 reads. The manual lists each value as 2 bytes (one register) and marks the setpoints as read/write; it gives no scale or unit for the temperatures, so values are the raw device counts. Check the scale against the display.",
    "Serial format: 8 data bits, no parity, 1 stop bit. The manual does not give a baud rate; the device address is 1 to 127.",
    "Status bits of register 40013: bit 0 SSR, bit 1 S1, bit 2 S2, each 1 when the output is on."
