User Manual/1. Chordata parts/1.2. Cables
The cables used to interconnect the sensing units on the Chordata system strongly resemble those used on domestic telephones. They are almost the same, just for the fact that in chordata they should have 6 cores, and the ones you normally use for telefones come with 4 or 2 cores.
If you are part of the beta-testing program you will receive the cables with your kit, otherwise you can crimp them your own.
Just make sure you have enough for the capture gear that are planning to use. For example for the default biped configuration you will be using 15 cables, but is better to have a couple of spare ones. For example this would be a good set:
- 7 cables of ~80cm
- 5 cables of ~40cm
- 5 cables of ~30cm
Crimp your cables
The easiest and cheapest way to get a flexible 6cores cable is to strip the jacket off from a regular Ethernet cable. It is important to get the cable with Stranded cores, since the solid ones are too rigid.
So, you will end up with a bunch of twisted pairs. Pick just three of them.
Twist them together and crimp the connectors using an RJ12 crimping tool.
The result should be something like this
Order of the wires
The order on both ends should be mirrored. The colors you pick are not important, but it is better to use the same twisted pair for adjacent pins. This table is just one example of a possible color configuration
