This is how Truck Town Thunder’s camera will be wired. I made a custom adapter to convert the serial and power wires to a Cat5e network cable jack, and another one to convert it back. This really seems like the most efficient way to connect the camera, since all the wires are in one neat little bundle, and it’s easy to get it long enough (It has to go from the top of the robot to the bottom, routed around the frame.)
I chose a patch cable because it uses stranded wires instead of solid, so it won’t break as easily.
Here’s the pinout I used. I tried to give the serial wires a bit of shielding by putting the ground to the other half of their twisted pairs. Each power wire gets its own pair to reduce resistance by half.
1-2. Power gnd
3. Serial gnd
4. Serial white
5. Serial gnd
6. Serial red
7-8. Power +
There were specific rules regarding the wire gauge of wire used for sensors this year. Are you sure your Cat 5 complies with them?
Yeah I believe Cat5e is 23 gauge (or is that Cat6?)
Cat5E is 24AWG, and Cat6 is 23AWG
You can find it at Wikipedia.
Yeah, the cable says 24awg on it, and according to this rule that is the perfect number (I was sweating there for a second…)
<R85> You must use 24 AWG or larger diameter wire for connecting sensors such as: switches, potentiometers,
accelerometers, and other sensors. You must use 24 AWG or larger diameter wire for connecting a Vision
System to Robot Controller inputs, and for extending the PWM cables, for the small muffin fans, or for
wiring LEDs. It is acceptable to use ribbon cable smaller than 24 AWG to connect to the 9 pin ports on the
