Star 3 multiplexer 19 pin connector wiring

[ljubomad]

Hello all,
Would you please send me with wiring diagram for Star 3 multiplexer 19 pin amphenol connector.
Multiplexer is "made in china" D4 clone.
9 wire, flat ribbon cable is connected from 10 pin connector on printed circuit board (FC-10PR) to the external 19 pin connector (on computer side).
Two ST232 C chips were used on the board (U103 and U 107).
Cable from 19 pin connector to PC is standard cable without RS485 ti RS232 interface.
Original wiring was damaged during shipping.
Thank You

You can find Mux schematic on the forum,and if you study a little you can connect without schematic too!
There are 2 Max232 converters near the pinouts.
RS232 port from PC conect directly to this 2 Max 232 .
Max convert ttl signall to rs232 standard.
Some exemple are in the pictures.
