Installation
(Continued)
Note that:
If two SDU/LONs are associated with IQLs which are on the same Lan, the SDU-LONs
must be on the same segment (i.e. on the same section of LonWorks separated by routers).
If the system is installed on a LonWorks Management Tool (as in step 12), this rule does
not apply.
