Connecting to Ethernet

IV.  Connections

ETHERNET CONNECTION (ALL MODELS)

A female modular RJ-45 jack on the rear panel is for connecting the RAVE unit to a 100baseTX Ethernet.

To connect the network cable to the RAVE unit, insert the RJ-45 male connector—with its locking tab

facing down, the only way the connector will fit into the jack—into the jack until the tab clicks into

place, just like connecting a modular telephone cable to a telephone.

To disconnect the network cable from the RAVE unit, grasp the connector and squeeze

up on the locking tab, then pull it out of the RJ-45 jack.

A 100baseTX network connection requires CAT-5 grade cable. The cable length between the

RAVE unit and a 100baseTX hub should not exceed 100 meters (328 feet).

Suitable Ethernet cable is readily available at most computer suppliers. To make your own, see

the Appendix for connector pinouts.

ANALOG AUDIO CONNECTIONS

Analog audio inputs and outputs connect through detachable terminal strip headers on the rear panel of the RAVE

unit. These detachable headers allow for pre-wiring of racks and quick connecting and disconnecting for

installation, removal, reconfiguration, or replacement.

The illustration at right shows how the detachable headers work. To connect a wire to a terminal:

RACK MOUNTING (ALL MODELS)

A RAVE unit is 1 RU (1 rack space) high and mounts in any standard 19-inch equipment rack. The top cover of

the chassis must be in place and properly secured with screws before you can mount the RAVE unit.

Use four mounting screws to fasten the front ears of the RAVE unit to the mounting rails of the rack.

The chassis of a RAVE unit also has mounting ears on its rear corners; if the rack also has rear rails,

it’s a good idea to support the RAVE unit in the rear, too. If you have several units stacked in the rack,

at least support the bottom one at the rear corners.

Dress and support any cables that are to attach to the RAVE unit so that their weight doesn’t put an

undue strain on their connectors when you attach them.

Be careful when installing the unit in an equipment rack; its cooling vents must not be obstructed.
Prendre soin lors de l'installation de l'unité dans un bâti d'équipement; on ne doit pas obstruer les bouches de ventilation.

Strip back the insulation on the wire about ¼ inch (approximately 6.3 mm).

Loosen the screw above the header terminal, then insert the wire fully.

Tighten the screw until the wire is firmly anchored. Do not overtighten.

Use a wire tie to secure the cable to the grip of the header block.

The detachable headers connect to and disconnect from the pins simply by pushing

on and pulling off.
