Subject: KStep - long ribbon cable
Tom,

I am trying to route my cables most efficiently with limited space in a small control panel. I have a Konnect, KStep, and KFlop. I am considering moving the KFlop to the interior of the door for access.

The Konnect manual says to keep the ribbon short because it makes a high speed connection. I am assuming that 2-3 feet would NOT be considered short. How about spitting up the KStep and the Kflop? Could I have several feet of ribbon between them without an issue? If the ribbon is a problem, would an ethernet cable with twisted pairs work okay to run the KStep remotely?

Thanks,

Scott

Hi Scott,

Its hard to give a definitive answer as it depends on the noise level in the system.  Noise and transmission line effects are complex.  All the connections are fairly high speed.  KStep might have higher noise margins.   Twisted pairs wouldn't be a good idea as the signals are not differential pairs.   Shielding may help.  Shielded ribbon cable exists that you might try if you run into problems.
