1) Make sure your wiring is straight through and not connected to any Telco punch
down blocks or a few as possible – they add interference. If your wiring is
spliced, use Telco butt clips or gel filled caps to bridge wire into a solid
connection. A flashing I n t e r l i n k S y n c L E D i n d i c a t e d t h e u n i t s a r e t r y i n g t o c o n n e c t t o

2) Check for a firm connection of the RJ-45 connections in each 865 unit, check any
splice points in the Interlink wiring and that the 5v power adapter is applied to the
865 CO and the 350 PoE injector is powered up.
3) You can always perform another out of the box test to prove out the equipment
and then focus on your interlink wiring.
4) If your installation has performance issues not resolved by the first two steps, you
can change the 865 CO DIP Switches (2 & 4) to the OFF position. See the
following chart for DIP switch settings.
