hello arci

Hi

I see a module transceiver MAX232 (convert interface for RS232 to TTL UART signal) ... Is it of your receiver ?

If yes !?!

On the connector (CON 3 PS103) there are the TX/RX signal converted to RS232 EIA (PC- standard) ...

[CON 3] You can take RXD (IN pin 1) - TXD (OUT pin 2) - GND (pin 3) for connected to RS232 DIP9 (serial comunication port) of your PC ...

For right connection on PC RS232 DIP 9 Female ... refer to standard pinout (RX/TX) !

P.S. On attached image ... there is the pinout of the MAX232 IC!
