On circuit diagrams, plugs are displayed as viewed from the back side, the solder side. Chips are displayed as viewed from above; also, see the small semicircular cut for finding the correct orientation. When in doubt, see the corresponding description on the legend page.
You need the following parts to build this cable:
One solderable user port plug
One solderable 25-pin male plug (PC parallel plug)
A shielded 8-wire or unshielded 9-wire cable of, preferably, at most 2 meters
Step 1. Solder one end of the cable onto the user port plug.
Step 2. Solder the other end of the cable onto the parallel plug. You should have the following connections:
|User port plug|| Parallel plug |
|A, GND||18-25, GND |
|C, PB0|| 2, Data 0 |
|D, PB1|| 3, Data 1 |
|E, PB2|| 4, Data 2 |
|F, PB3|| 5, Data 3 |
|H, PB4|| 6, Data 4 |
|J, PB5|| 7, Data 5 |
|K, PB6|| 8, Data 6 |
|L, PB7|| 9, Data 7 |
You can find the description of all parts used on the diagrams at the legend page.
