Power Connections
The preferred method of powering a VIP-851 is via
a Power over Ethernet Plus (PoE+) switch meeting
the 802.3at specification.
If the rear panel barrel connector is used for power,
the preferred power supply is a Valcom VIP-1124D.
Make all required signal connections before
applying power to the unit. If powering via 802.3at,
make sure all signal connections via the back panel
are made then connect the VIP-851 to the Ethernet
switch.
If power is supplied via the barrel connector, make
sure all signal connections are secure. Attach the
unit to the network via the front panel RJ-45
Ethernet connector. Apply power by plugging the
power supply into the
connector on the rear of the VIP-851.
Network Connection
The VIP-851 has one RJ-45 network connector on
the front panel. Use a standard Ethernet patch
cable to connect the VIP-851 to an Ethernet switch.
Signal Connections
The VIP-851 has signal connectors on the rear
panel:

AUX audio input

1 Contact Closure input

2 Audio outputs (VIP-851-25)

3 Audio outputs (VIP-851-70/100)

1 Form C relay
AUX Audio Input: Line-level audio may be input
via the rear panel screw terminal block labeled
AUX. Nominal input impedance is 600 Ohms.
Audio connected on AUX can be directed to the
locally-connected speakers (Outputs connections)
or across the network to other Valcom devices.
Audio input is typically used for Background Music,
and will be muted during a Page.
Contact Closure Input: Contact closure input
labeled CC is provided for connecting an external
contact (relay, switch, etc) to trigger actions in the
VIP-851. The contact closure can be programmed
to activate the AUX Audio Input to send audio
across the network, or to remotely activate a relay
on another Valcom device across the network.
