Table 14: Maximum number of devices per LonWorks network segment
Device Type
Notes:
• Each LPT10/11 channel segment (between repeaters) requires its own power supply. Other factors, such
as power consumption of individual LPT10/11 devices, may limit a segment to fewer devices.
• The MS-NAE552x-x models that support LonWorks Network trunks do not have an internal network
terminator.
