I have a recording device with a 9 pin dsub connector for control.
Pin 1 == Ground
Pin 2 == TxD
Pin 3 == RxD
Pin 5 == S. Ground
4&6-9 == NC
I'd like to use the 40pin header on a raspberry pi B+ to send commands to this device.
What is the cleanest way to connect these pins to a DSub connector?
A cable with a male DE-9 connector on one end and wires connected to an IDC on the other is what I have in mind but I'm not sure how well the wire gauges match or where to order the parts.
Any advice?
