    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 (www.echelon.com). 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.

No such topology rule applies to the use of TP/XF-78 control modules, TPT/XF-78 transceivers, or TPM-78 SMX transceivers. Referred to as the “8-in-16” topology rule, this rule requires that no more than 8 TP/XF-1250 Control Modules, TP/XF-1250 Transceivers, or TPM-1250 SMX Transceivers be located within any 16 meter length of cable.

    Figure 12. Using a Router to Meet the 8-in-16 Topology Rule The second remedy to a violation of the 8-in-16 rule is to add additional cable to the bus such that the rule is no longer violated (see Figure 13). It is important to ensure that the maximum bus length (130 meters of 22 AWG [0.65 mm] Level IV or AWG 24 [0.511 mm] ANSI/TIA/EIA-568-B.2-2001 Category 5 or Category 6 twisted-pair cable) is not exceeded by the additional cable.

For a 4-layer PCB, the ground plane serves to distribute ground from the center of the star ground out to the various function blocks in the floorplan. For a 2-layer PCB, ground pours should be placed on the bottom layer (and also on the top layer where possible) in order to connect the grounds of the various function blocks to the center of the star ground.
