4 wire interface cable for Telex BTR 800/80N
Increasingly, wireless intercoms are attached to fiber systems which necessitates utilizing “four wire” operation of the Telex BTR800 and BTR 80N RF intercoms. A four wire interface cable separates the send and receive portions of the party line between male and female XLR connectors. The send and the receive is connected to the intercoms four wire input via an RJ 11 connector. This is the ideal situation for interfacing with modern digital matrix intercom systems.
