Install the waterproof DB15 male connector on the RRU alarm cable with caution, preventing the pin assignment
from being damaged.
Step 3 Connect the eight cord end terminals at the other end to external alarm devices.
Use insulating adhesive tapes to wrap cord end terminals that are not in use and fix them at a proper position
based on the onsite situations. This prevents false alarm reporting and equipment damage due to contact of
exposed cables.
