5.1 Setttings
(2) Using RS-232C
Pin 8: Sets to 0 for RS-232C.
Pin 7: Specifies the bit length. 0: 8 bits, 1: 7 bits
Pin 6: Specifies whether parity is valid or not. 0: Invalid, 1: Valid
When 1 (Valid) is specified, the pin-5 setting becomes valid.
Pin 5: Specifies the parity. 0: Odd, 1: Even
Pin 4: Sets the stop bit. 0: 1 bit, 1: 2 bits
Pin 3: Specifies the speed for S3.
Pin 2: Specifies the speed for S2.
Pin 1: Specifies the speed for S1.

POINT
The changed DIP switch setting becomes valid after
the next power on. So, for using the MT9812B with the
changed switch setting, turn the power on again.
