Note: Power requirements for the DC 5900 F discussion unit vary depending on the configuration of the unit. Addi-
tional discussion units are supported when the loudspeaker is removed and when GM gooseneck microphones
are used instead of the MX4xx series microphones.
Using Junction Boxes
The JB 6104 junction box adds four additional outputs to a point on the DCS-LAN chain. These four outputs are
available for short-run connections to DUs, protecting the DCS-LAN chain from technical failures or hot-plugging
damage. A single DU can connect to each JB output, with a maximum cable length of 10 m.
