The OP has correlated the pinout of the DB9M serial connector to the
pinout of the IC.
Contact pin DB9M - pinU4:
pin1 - pin15 SDI;
pin2 - pin4 SDD; <----- should this be SDO ?
pin3 - pin 5 ONBAT NO;
pin4, 9GND - pin7, 8 GND;
pin5 - pin9 LOBAT NO;
pin6 - pin6 ONBAT NO;
pin7 - pin13 REMOT IN;
pin8 - svoboden (= free, not connected)
