The VL-CONF-4 is designed for wall, table or rack

mounting.

Table: Provided with the VL-CONF-4 are four

rubber pads. Peel the pads from their carrier

backing and place at the four corners of the bottom

of the unit.

Wall: Using the template on last page of this

document, mark the location of the bracket screw

holes on the wall. Drill 5/64" pilot holes, 3/4" deep,

at each screw location and use the wood screws

provided to attach the brackets to the wall. For

surfaces other than wood, use hardware

appropriate for the surface (not included). With the

brackets securely attached to the wall, attach the

VL-CONF-4 to the brackets using the included

hardware. Figure 2 illustrates the bracket

assembly.

Rack: Following the assembly drawing, attach the

two mounting brackets to the VL-CONF-4 unit.

used connect an audio patch cable with male

phono connectors between the conference

bridges.

Setup

Information specific to your application will need

to be programmed into the gateways and audio

ports using a computer. The PC used for

programming should be connected to the same

subnet as the Valcom gateways and audio ports.

Setup will be done using the IP Solutions Setup

Tool. Download the latest version of the free IP

Solutions Setup Tool from the Valcom web site at

www.valcom.com/vipsetuptool.

OPERATION

Port 1 of the conference bridge is the activation

port. The initial user lifts the handset on a

conference telephone. At that time the remaining

telephones on the bridge begin to ring. When the

telephones are answered the users are connected

together in a conference call. When a user hangs

up from the conference call they cannot rejoin the

call.
