Precautionary Designations
Mounting
The VIP-204A SIP Paging Gateway is designed
for rack, shelf, or wall 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.
Shelf:
Provided with the VIP-204A SIP Paging
Gateway are four rubber stick-on pads. Peel the
pads from their carrier backing and place at the
four corners of the bottom of the unit.
Wall:
Using the brackets and wood screws
provided, secure the VIP-204A SIP Paging
Gateway to the wall.
Power Connections
The preferred method of powering a VIP-204A 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-204A has one RJ-45 network connector
on the front panel.
Use a standard Ethernet patch cables to connect
the VIP-204A to an Ethernet switch. If the
Ethernet switch is 802.3af compliant, it will power
the VIP-204A.
Signal Connections
The VIP-204A 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
broadcasts to all Audio Outs whenever they are
idle. This is typically used for background music.
Input / 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-204A. 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.
N.O. Relay Closure Output:
The Normally
Open Relay Closure Output connection can be
programmed on the VIP-204A 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
