RU & RM will not fully LINK to a Gateway (GWE) if the communication bus of the RU/RM mainboard to the DPS module is defective.
With the DPS COM fault, the LINK symptom after OK LINKING is an incomplete and partial link,
1) Gateway "Managed Linked devices" shows RU/RM LINKED in the GWE "Linked Devices" list; but with no signal, only a gray triangle with a slash, regardless of the signal strength
2) RU/RM behaves like it is not LINKED, the RU/RM shows in the "In Range" and allows connection with the Mobile APP; without de-LINKING first.
As a Corrective action, fix the DPS communication serial bus by repairing the wires or connector for the DPS module.
After fixing the DPS COM; FDR the RU/RM, and LINK again to the GWE. Signal should now display correctly, and the LINKED RU/RM will not be listed in the "Nearby" list;
