Programming cable for COM1
You can use a 1:1 cable for programming the BX Controllers (socket/plug, and only connect the pins listed below). On the BX side you need a nine-pin connector, and on the PC side usually a nine-pin socket. The wiring is 1:1, and the necessary pins can be found in the table below. The length of the cable should not exceed 5 meters!
