1. Grounding pin. This pin is for grounding the chassis of the expander.
2. AC Power inlet
3. AVB/ Control Connection. Uses a standard RJ-45 connector with CAT-5, CAT-5e, CAT-6 or CAT-7
cabling. The maximum distance between any unit and an Ethernet switch is 328 feet (100 meters).
This connection is for sending and receiving AVB audio signals as well as sending and receiving data
between the expander device and the Tesira system. An expander will not operate if it is not on a network
that includes a Server-Class Tesira device.
4. Audio Slots. These slots may be optionally factory loaded or field loaded with EX-MOD audio cards. The
audio connection on the cards are electrically balanced and are configured for use with shielded-twisted-
pair wiring. The wires are to be terminated in the three-pin removable connectors according to the wiring
diagram shown on the unit. The wiring diagram is also displayed on the connectors themselves. The
connectors may then be inserted into the mating connectors on the expander. In the illustration above,
channel one on the card in Slot 1 is shown without the removable connector inserted.
