4-Wire Intercom Connectivity

Always confirm that the non-Pliant 4-Wire intercom system and the CrewCom wireless system are functioning properly separately before connecting them together. Use the procedures below to configure the 4-Wire connection from the CU's Wired Settings menu.

TIP: See Intercom Settings Menu for more information about navigating this CU menu.

Under the Wired Settings menu, select Intercom Settings:

1. Use the Navigational controls to navigate to the desired setting for a 4-Wire port (CCU-22 ports 3 and 4; CCU-44 ports 5 through 8; CCU-08 ports 1 through 8).
   1. For intercom type, press Enter to turn the port on or off; use the navigation buttons to scroll through the list, and press Enter when the desired setting is highlighted.
   2. If desired, enable Echo Cancellation (ECAN) for the 4-Wire ports. See the Echo Cancellation section of Intercom Settings Menu for more information.
2. Now that your settings are established, connect the 4-Wire intercom system to the appropriate ports via RJ-45 cables/connectors.
3. Adjust in/out audio levels between the CrewCom System and the 4-Wire intercom system as needed.
   1. With appropriate mic gain settings and expected nominal levels from the interfaced system, the 4-wire settings you can expect to see for RTS, Clear-Com, and Riedel are provided in the table below.

      4-Wire Intercom Settings
      	RTS	Clear-Com	Riedel
      4W OUT	+2	-3	+1
      4W IN	-2	+3	-1

4. If you need conferences for 4-Wire other than the default conferences, you will need to create new conferences in CrewWare and assign the new conferences to the wired ports. (See Conference Management Tab and for more information on creating Conferences. See Configure a 4-Wire Connection via CrewWare for more information about this process.)

Always confirm that the non-Pliant 4-Wire intercom system and the CrewCom wireless system are functioning properly separately before connecting them together. Use the procedures below to configure the 4-Wire connection from CrewWare.

On the Device Management tab, open the Control Unit's detail view:

1. Find the "4-Wire" panel.
2. Locate the desired setting for a 4-Wire port (CCU-22 ports 3 and 4; CCU-44 ports 5 through 8).
   1. Select a conference for the port in the Assigned Conference drop-down field. If you need conferences for 4-Wire other than the default conferences, you will need to create new conferences from the Conference Management Tab and choose the new conferences in this field.
   2. For the 4-Wire Type field, select either ON or OFF.
   3. The Audio Mode field is limited to only selecting Duplex at this time.
   4. If desired, type a 16-characters or less Port Name in that field.
   5. Adjust in/out audio levels between the CrewCom System and the 4-Wire intercom system as needed. Within CrewWare, adjust the CrewCom levels for each 4-Wire port via the Level In and Level Out fields.

      With appropriate mic gain settings and expected nominal levels from the interfaced system, the 4-wire settings you can expect to see for RTS, Clear-Com, and Riedel are provided in the table below.

      4-Wire Intercom Settings
      	RTS	Clear-Com	Riedel
      4W OUT	+2	-3	+1
      4W IN	-2	+3	-1

   6. If desired, enable Echo Cancellation (ECAN) for the 4-Wire ports. See the Echo Cancellation section of Intercom Settings Menu for more information.
3. Now that your settings are established, connect the 4-Wire intercom system to the appropriate ports via RJ-45 cables/connectors.
