1.
RS-232 and RS-485 baud rates: 9600bps, no odd or even calibration address, 8bit
data transmission address, 1bit stop address (96, N, 8, 1).
2. To use the above matrix function, you have to set the RS-232/LAN pin to RS-232
mode and the ID must not be 31 (ALL OFF). Refer to
6.6.5 DIP Switcher 8 Pins.
