Programming Cables

[chicobatera]

Hello!

I'm currently soldering all components on my PCBs, building the 32 inputs version. However, I'm having some trouble understanding the schematics of the programming cables. In fact, I don't know how to make them. Should I solder the resistors into a cable, connect the resistors directly to my PC ports or make another PCB with resistors between wires from the digital board and the connectors? Or is there any other alternative?

Thanks a lot,
Francisco.

They are wired just as they appear in the schematic; it's a cable with a connector at each end: a female connector that plugs into the digital board header, a com/lpt connector that plugs into your pc, and resistors in between - if you solder the resistors directly to the com or lpt connector pins (the back of it that is, where the cable connects to it), you can keep it nice and tidy as they fit in the casing. Here's a photo (without resistors) so you can see where I mean they go.
