well if the control head cable is 6 pin, then you can't use cat5 because 
cat5 is 8 conducter, and RJ45's are 8 pin.
You have to use that flat telephone or network type cable with 6 conducter, 
and the RJ12 six pin jack...which is the same size as the RJ45, but only has 
six pins instead of 8 on the plug.
I would imagine you can probably find shielded 6 conducter cable though just 
like you can get shielded 8 conducter which is cat6.
