Q3. On a segment where an FVX110 works
as the LAS, another device cannot be
connected. How come?
A3-1. Check the following bus parameters that
indicate the bus parameter as being the
LAS for the FVX110 and the capabilities of
being the LAS for the device that cannot be
connected:
• V(ST), V(MID), V(MRD) of FVX110:
ConfiguredLinkSettingsRecord (index 385)
• V(ST), V(MID), V(MRD) of problematic
device: DlmeBasicInfo
Then, confirm that the following conditions
are met:
FVX110 Problematic
Device
V(ST) > V(ST)
V(MID) > V(MID)
V(MRD) > V(MRD)
A3-2. Check the node address of the problematic
device is not included in the V(FUN)+V(NUN)
