k-pod data cable

[Jean-François Ménard]

Hi Noel

Usually, such typical serial communication, like RS-232, could handle 15m with proper cable gauge and shielding. This cable has short transmission distance because of noise limiting the transmission of high numbers of bits per second.

But in our case here, strong RF field is involved when transmitting, so the distance could be much shorter than 15m to avoid data corruption. I would strongly suggest to try using a cable made with shielded CAT6 cable, not standard ribbon cable usually used for phone,etc. Adding a few clip-on ferrite at both ends with as much turns you can could be a great addition too avoid misleading with unwanted noise in the communication line and ground path.

Hope this help.

This is a station design problem beyond K-Pod wiring.

Hi,

Unfortunately, something I did not mentioned in my previous post, it was implicite for me, but by using CAT6 cable, I was thinking about making our own cable and connectors to avoid using flat ribbon cable.

The twisted part of the cable will improve communication reliability for sure. Noel mentioned to me that he needs a cable run approximately 25 feet long. My guess, this should work. But many other factors must be involved, like "how the station has been properly setup? », and so on.

Experimentation here is the key…. an important part in our hobby. :-)

Not to mention, are the signals in the K-POD on the same pins as Ethernet, therefore, you’re using the pairs on the +ve & -ve sides of the signals, or if different, you be mixing signals across the pairs?

And also a knowledge of fundamental concepts.
