Wire Characteristics
Due to the many cabling and termination options available for the TP/FT-10
channel, please refer to the
Series 5000 Chip Data Book
,
FTT-10 Free Topology
Transceiver User's Guide
, or
FTT-10A Free Topology Transceiver User's Guide
, as
applicable, for information on wire characteristics and terminations.
The
Junction Box and Wiring Guidelines for Twisted Pair LonWorks Networks
engineering bulletin (005-0023-01) provides a list of cable vendors for each type of
supported cable. This bulletin is available from the Echelon Web site
Cable Terminations – Free Topology
In a TP/FT-10 free topology segment, only one termination is required and can be
placed anywhere on the free topology segment. There are two choices for the
termination:
1.
RC network (see
), with R1 = 52.3
Ω
.
2.
LPI-10 or LPI-11 Link Power Interface, with jumper at "1 CPLR" setting.

Cable Terminations – Doubly Terminated Bus
In a TP/FT-10 doubly terminated bus topology, two terminations are required,
one at each end of the bus. There are two choices for each termination:
1.
RC network (see
), with R1 = 105
Ω
.
2.
LPI-10 or LPI-11 Link Power Interface, with jumper at "2 CPLR" setting
if resident on a link power segment. Only one LPI-10 or LPI-11 Interface
