INSTALLATION
Mounting
The VIP-204B SIP Paging Gateway is designed
for rack mounting.
Rack:
Attach the brackets to the four holes
closest to the front on each side, and then mount
the unit to a 19” rack. (See Figure 1).
Figure 1
CONNECTIONS
All wiring connections (except Network) are
located behind the cover plate at the rear of the
VIP-204B. Remove two screws holding the cover
plate to access the connections. Replace the
cover plate when all connections have been
made. (See Figure 1)
Power Connections
The preferred method of powering a VIP-204B is
via a Power over Ethernet switch meeting the
802.3af specification.
If the rear panel barrel connector is used for
power, the preferred power supply is a Valcom
VIP-324D.
Make all required signal connections before
applying power to the unit.
Network Connection
The VIP-204B has one RJ-45 network connector
on the front panel.
Use a standard Ethernet patch cable to connect
the VIP-204B to an Ethernet switch. If the
Ethernet switch is 802.3af compliant, it will power
the VIP-204B.
Signal Connections
The VIP-204B has 5 signal connectors on the
rear panel:
• 1 RCA jack for AUX audio input
• 4 RJ-45 connectors for audio and relay
connections for each networked channel.
AUX Input:
Local audio may be input via the
rear panel RCA jack. Nominal input impedance
is 600 Ohms. Connect any compatible audio
source using an RCA patch cable. Audio
supplied through the rear panel RCA jack can be
programmed to broadcast to any of the Audio
Outs when they are idle. This is typically used for
background music
Output Connections:
Access to the audio
output and relay output for each of the four
channels is provided through the four RJ-45 jacks
on the rear panel of the VIP-204B. Four patch
cables and four VM-186 terminal block
connectors are included for ease of installation.
The following chart shows the pin assignments
for the four input/output connections.
(See Figure 2)
N.O. Relay Closure Output:
The Normally
Open Relay Closure Output connection can be
programmed on the VIP-204B to close the
contacts in response to paging events. The relay
will return to the open state when the event ends.
Audio Output:
Typically connects to Self
Amplified Speakers or into an amplifier. Audio
feeds connected to the AUX Input mute on any
active Audio Output.
Status Indicator Lights
The VIP-204B has 3 status indication lights on
the front panel:
STATUS:
Flashes during normal operation and
solid during system startup.
Green LED:
(Link) Indicates Ethernet connection
when illuminated.
Yellow LED:
(Activity) Indicator flashes to
indicate network activity.
