Power Requirements

For most installations, the DIS-CCU supplies sufficient power for the discussion units. Depending on the setup, the CCU
powers up to 50 units at a time without additional equipment. The number of supported discussion units depends on the
size and layout of the installation.
Note: maximum cable length in one chain is 120 m before a repeater unit.
① One to four outputs for discussion
unit chains
② Length from DIS-CCU to first unit
③ Distance between participants
Power Depends on Installation Variables
To maximize the unit count without adding equipment:
1. Use multiple chain outputs from the CCU. Units must be divided evenly across each chain
2. Position the CCU so that the cable distance to the discussion unit chain is as short as possible
3. Keep the total cable length as short as possible by decreasing space between units
