6.5 Connector Wiring
These are connector diagrams with pin designations. All connectors on these pages are shown looking
at them from the outside, not from the solder side. These diagrams look at the outside of the connec-
tor, as the cable sees it, not the wiring side.

This little 9-pin to RJ45 adapter is available
unwired from many computer or electronic
stores. Get one with a female 9-pin connector.
The RS232 cable must be wired straight-thru. You
can tell if a cable is wired straight-thru by looking at
its two ends side-by-side.
1. Hold the cable ends next to each other, both ends
pointing away from you. Have the clips on both
connectors pointing down so you can't see them.
2. If the color of the wires on the two connectors is
the same, left to right, the cable is straight-thru.
The order of the colors doesn't matter, as long as
they are both the same.
