2. MA remote controller transmission
The communication between the MA remote controller and the indoor unit is performed with current tone burst.
(1) Symptoms caused by noise interference on the transmission line
If noise is generated on the transmission line, and the communication between the MA remote controller and the indoor unit
is interrupted for 3 minutes in a row, MA transmission error (6831) will occur.
(2) Confirmation of transmission specifications and wave pattern
A, B : No polarity
Across terminal No. 1-2
: Power supply (9V to 12VDC)
Satisfies the formula
12 msec/bit 5%
Voltage among terminals must
be between DC9 and 12 V.
