Making cables to mate with the Fastrack’s high-density ‘D’ connector is fiddly and labour-intensive (ie, expensive).
For normal ‘D’ connectors, it’s easy to get them with IDC (Insulation Displacement Connection) - where all connections can be made at once in one simple operation; eg:
The "The “High-Density D Connector” on Fastrack is basically same as “VGA” connector used on PC and monitors. So it is cheap and easy to find.
Actually I had make a PC-to-Fastrack cable by cutting a standard 9 pin RS-232 cable; a VGA extension cable, and then soldering apporiate cables together
Of course for large quantity you should go for cable assy factory.
Sure, the connector itself is easy to find - but only with individual wire trminations.
For high-volume applications like VGA cables, assembly could be outsourced to a low-labour-cost area.
But I’m talking about small-to-medium volumes where a one-step operation would give a significant saving over having to individually terminate the 15 wires.
I think that’s no easier than using the insertable pins 8)
