Configure a 4-Wire Connection
Always confirm that the non-Pliant 4-Wire intercom system and the CB2 wireless system are functioning properly separately before connecting them together. Use the procedures below to configure the 4-Wire connection from the BaseStation's Wired Settings menu.
Under the Wired Settings menu, select Intercom Settings:
- Use the Navigational controls to navigate to the desired setting for a 4-Wire port.
- 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.
- If desired, enable Echo Cancellation (ECAN) for the 4-Wire ports. See the Echo Cancellation section of Intercom Settings Menu for more information.
- Now that your settings are established, connect the 4-Wire intercom system to the appropriate ports via RJ-45 cables/connectors.
- Adjust in/out audio levels between the CrewCom System and the 4-Wire intercom system as needed.
- 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.

More About the CrewCom 4-Wire / RJ-45 Connection
Wiring schemes vary, and it is important to ensure that the cable is wired correctly for proper system operation. The CB2 BaseStation utilizes RJ-45 jacks for connection to a 4-Wire port. Only two pairs of wires are utilized—one to send audio and one to receive audio. Any twisted pair wiring can be used to connect between the 4-Wire and the CB2 wireless system. See the table below for a list of the 4-Wire RJ-45 pin connection list.
Note: Pins 1 and 8 are tied, and pins 2 and 7 are tied.
