Configuration Notes:

•Customer setup length L1, i.e., the total length of flat metal cables, should not exceed 16 m - L2. addition, be sure to use the flat metal cable with the core diameter of 0.65 mm.

•The modular rosette is the customer responsibility, and hence not included in the router. Procure that has the model name MJ-8S (no terminator).
