The 9pin that the spakers and volume control are soldered on too came apart from the wires. I want to solder the wires back on but i am not sure which wires go on what pin. need help.
I have a logitech z3 subwoofer with a mini-DIN-9 connector socket. It also has a volume control and 110V power cord. As best as i could trace the circuit, and using the TDA7377 stereo bridge amplifier chip datasheet, the pinout for the mini-DIN is as follows (untested):
1: L in (to vol.)
2: R in (to vol.)
3: Power (12V from transformer)
4: Standby (5V to play, 0.05mA; 0V to standby)
5: L out
6: R out
7: Ground
8: Ground
9: Ground
Connecting 3 to 4 with a large resistance (~20K ohms) should enable speaker. Pins 1 and 2 might be swapped; pins 5 and 8 might be swapped. Mini-DIN socket pin holes are numbered right to left, bottom row to top row:
9 8 7
6 5 4 3
2 1
SOURCE: logitech x-230 9 pin problem . i need to manualy
worked on this for 3 days but i finaly got it I had to open it an follow coper lines using datasheet, the connector is RS232 the pins are
1 = LED+
2 = IN R
3 = OUT R
4 = OUT L
5 = GND
6 = ON
7 = 5V
8 = GND
9 = IN L
so you have to put a swiths between pin 6 and 7
you should also put a potentiometer GND-IN-(AUDIO SOURCE)
and a led between pin 1 and GND
and that is it!
