2-Wire Intercom Connectivity

Always confirm that the non-Pliant 2-Wire intercom system and the CrewCom wireless system are functioning properly separately before connecting them together. Use the procedures below to configure the 2-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 2-Wire port (CCU-22 ports 1 and 2; CCU-44 ports 1 through 4).
   1. For intercom “Type,” press Enter to view the available list of compatible types: RTS Ch 1, RTS Ch 2, AudioCom (Balanced), or Clear-Com. You can also select Off. Use the navigation buttons to scroll through the list, and press Enter when the desired setting is highlighted.
   2. Determine if you would like to send and receive Call signals from CrewCom to the connected 2-Wire intercom system. Press Enter to view and select ON or OFF. See the Call section of Intercom Settings Menu for more information.
   3. If desired, set Mic Kill to send and receive signals from a connected 2-Wire intercom system. Press Enter to view and select ON or OFF. See the Mic Kill section of Intercom Settings Menu for more information.

      Note: CrewCom does not send Mic Kill to Clear-Com 2-Wire systems.

   4. The Echo Cancellation (ECAN) setting for the 2-Wire ports is on by default. Pliant highly recommends that ECAN remain on even if a 2-Wire system is not in use. If you wish to change this setting, press Enter to view and select ON or OFF. See the Echo Cancellation section of Intercom Settings Menu for more information.
2. Now that your settings are established, connect the 2-Wire intercom system to the appropriate ports via 3-pin XLR cables/connectors.
3. After connecting the 2-Wire intercom system, initiate Auto Null for the appropriate ports or all ports of this particular CU. See for more information.
4. Adjust IN/OUT audio levels between the CrewCom System and the 2-Wire intercom system as needed.
   1. With appropriate mic gain settings and expected nominal levels from the interfaced system, the 2-Wire settings you can expect to see for RTS, Clear-Com, and AudioCom are provided in the table below.

      2-Wire Intercom Settings
      	RTS	Clear-Com	AudioCom
      2W OUT	0	0	+3
      2W IN	0	0	-3

5. If you need conferences for 2-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 Conferences Tab and for more information on creating Conferences. See Configure a 2-Wire Connection via CrewWare for more information about this process.)

Always confirm that the non-Pliant 2-Wire intercom system and the CrewCom wireless system are functioning properly separately before connecting them together. Use the procedures below to configure the 2-Wire connection from CrewWare.

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

1. Find the "2-Wire" panel.
2. Locate the desired setting for a 2-Wire port (CCU-22 ports 1 and 2; CCU-44 ports 1 through 4).
   1. Select a conference for the port in the Assigned Conference drop-down field. If you need conferences for 2-Wire other than the defaults, you will need to create new conferences from the Conferences Tab and choose the new conferences in this field.
   2. For the 2-Wire Type field, select from the list of compatible types: OFF, RTS_Ch1, RTS_Ch2, AudioCom, or Clear-Com.
   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 2-Wire intercom system as needed. Within CrewWare, adjust the CrewCom levels for each 2-Wire port via the Level In and Level Out fields.With appropriate mic gain settings and expected nominal levels from the interfaced system, the 2-Wire settings you can expect to see for RTS, Clear-Com, and AudioCom are provided in the table below.

      2-Wire Intercom Settings
      	RTS	Clear-Com	AudioCom
      2W OUT	0	0	+3
      2W IN	0	0	-3

   6. Determine if you would like to send and receive Call signals from CrewCom to the connected 2-Wire intercom system. Toggle the Call Enabled: (Inbound) and Call Enabled: (Outbound) functions on or off for each CU 2-Wire port. See Set Up Call for more information.
   7. If desired, set Mic Kill to send and receive signals from a connected 2-Wire intercom system by toggling the function to On. See the Mic Kill section of Intercom Settings Menu for more information.

      Note: CrewCom does not send Mic Kill settings to Clear-Com 2-Wire systems.

   8. The Echo Cancellation (ECAN) setting for the 2-Wire ports is On by default. Pliant highly recommends that ECAN remain on even if a 2-Wire system is not in use. If you wish to change this setting, you may toggle it to Off. See the Echo Cancellation section of Intercom Settings Menu for more information.
3. Now that your settings are established, connect the 2-Wire intercom system to the appropriate ports via 3-pin XLR cables/connectors.
4. After connecting the 2-Wire intercom system, initiate Auto Null for the appropriate ports or all ports of this particular CU. See for more information.
