What are the cable requirements and/or cable sources for the TP/FT-10, TP/XF-78, and TP/XF-1250 twisted pairs channels?
TP/FT-10 is either a free or a bus Topology channel, TP/XF-78 and TP/XF-1250 are both bus topology channels only.
The cable requirements and/or cable sources for the these channels are found in the 'Junction Box and Wiring Guidelines' engineering bulletin at
The bulletin also contains a list of cables (along with manufacturer/supplier information) that comply with Echelon wire guidelines.
Echelon does not validate whether a cable meets our wire specification. Cable manufacturers submit their cable to be included with the 'Junction Box and Wiring Guidelines' engineering bulletin.
If you want to see if a cable meets our specification then please ask the cable manufacturer to check whether their cable meets the 'Junction Box and Wiring Guidelines' checklist. If it does then the cable manufacturer can contact Echelon to have their cable included in the next version of the 'Junction Box and Wiring Guidelines'.
