2.3.2.1 Commentary Control Unit connection
When the CU is working with a CCU, in addition to the micro-headphones for
commentators 1, 2 and 3, and the guest commentator microphone or tape
input, the links with the CCU also have to be wired.
When it works in conjunction with the CCU, a single 4 pair cable fitted with RJ
45 connectors receives and sends all the digitally multiplexed CCU working
signals, including the power supply and the analog telephone line.
The cable used must be a AWG24, STP or FTP Category 5 type, with four
twisted pairs. The connection at both sides will include the ground connection.
The male connector used will be a RJ-45, shielded, AMP-5-569530-4 or similar.
If a female-female extension is used, the ground connection (shield) continuity
must be granted.
With the wire described above a distance of 300 m. can be covered. In 2.3.2.5.
section, the equalization switch is described which must be set depending on
the length of the cable to be greater or less than 150 m.

The connections between the CCU and each of the C Us
are made without crossing the wires, maintaining the
relative position of the conductor in the RJ 45 connector.
The connector wiring is given below, showing the signals
carried by each conductor.
