Build Your Own Custom Cable without the Hassle of the Welding If you don't like soldering when make the RS232 connection, this simple DB9 solerless connector is a quick way for you to insert the wire, so much easier than melting the pins and soldering them in place. PCB board's solder joints are named pin 1 to pin 9 (DCD, RXD, TXD, DTR, GND, DSR, RTS, CTS, RI), enables you to make quick connections, and to color code per terminals. Pure copper plated joints on the PCB board and DB9 connector's gold plated contacts for you to make a reliable signal connection. The case housing is designed with folding buckle, which enables you to make a easy assembly and disassembly without tool. The DB-9 female connector are well made and have enough space inside to make it easy to connect,and then route the wire fairly easily.
