Inputs

NOTE : The audio input sources (TOSLINK or analog stereo input) are mixed with Voice Lift and aux audio inputs. The TOSLINK and stereo analog audio inputs are selectable (not simultaneously mixed). The default mode is “Autos itch” which automatically switches between the two inputs upon signal detection. The 5-pole analog stereo input has priority over TOSLINK

Power input — Connect the provided power supply to this 2-pole captive screw connector. Wire the connector as shown at right.

ATTENTION :

Do not connect the power supply before reading the Attention in the Power Supply section of the PVCA 452 User Guide.

Amplified audio output — Connect speakers to this 5 mm captive screw

4-pole connector (shown below). The amplified audio is capable of outputting 50 watts (2 x 25 watts RMS) for 4 and 8 ohm speakers.
To terminate the cable, strip the end of the cable 0.2 inch (5 mm) and secure the wires into the supplied 4-pole captive screw connector as shown below.

Speaker Wire Color	To PVCA 452 Terminal(Left and Right)
Red	Positive (+)
Black	Negative (-)

HDMI/CEC/ARC — Supports HDMI ARC (Audio Return Channel) audio and CEC (Consumer Electronics Control) over a HDMI cable when connected to a display that supports these features. When configured, this allows the display to send it audio, over the HDMI cable, to the PVCA 452

Control Ports

Paging sensor port — Connect the optional Priority Page Sensor (PPS 35 or PPS 25) to this port, to enable program audio ducking during paging system broadcasts.

NOTE : The Extron Priority Page Sensor is an optional accessory, purchased separately (see the Extron website for details about the Priority Page Sensors). For page sensor installation and operation details, see the PVCA 452 User Guide available at www.extron.com

COM RS-232 port — Use this port to control external devices, such as the display device.
Control Ports

NOTE : If you use cable that has a drain wire, tie the drain wire to ground at both ends.

COM 1 Terminal	RS-232 Cable Color	Pin
Ground	Shield	5
Rx	Green	3
Tx	White	2

IR serial port — For IR control of a source device, connect an IR emitter to this 3.5 mm captive screw 2-pole connector (see figure 2). Adhere the IR emitter to the IR receive location of the source device (supports 30 kHz to 300 kHz, with or without carrier signal)

NOTE : For unidirectional RS-232 control, wire the transmit (TX) wire to the “S” port, and ground to the “G” port. Then, wire the appropriate connection to the device being controlled.

Digital I/O port — Connect two digital inputs or outputs, such as sensors or contact closure buttons, to this captive screw connector

Digital I/O (digital input/output)
Conguero each port as a digital input or output, with or without +5 VDC pull- up.

Use these ports to:

Monitor or trigger events and functions (toggle relays, issue commands, send e-mail), once congaed.
Power LEDs or other devices that accept a TTL signal.

rebus port — Connect an rebus endpoint device to this captive screw connector.

rebus Accessory Port
Connect the rest rebus device to this port, then connect other rebus devices and accessories to that device in the desired topology (daisy chain, star, or combination)

Wire the connectors the same at both ends for every rebus device.
See the rebus Technology Reference Guide for the recommended distance from the control processor to the last rebus device and maximum quantity of devices per control processor.
The PVCA 452 provides 3W of power, which can be used to power rebus button panel devices

LAN port — This port allows communication with the PVCA 452 via TCP/IP for controlling devices over the network, firmware updates over the network, as well as configuration and operation using PCS, Global Configurator, and Campus Communication Suite

NOTE : The factory configured password for this device has been set to the device serial number. Passwords are case sensitive. Performing a Reset to Factory Defaults sets the password to Extron.

PVCA 452 Configuration

The PVCA 452 amplifier can be controlled and configured using Extron Product Configuration Software (PCS), Global Configurator Pro/Plus (GCP), and Toolbelt via a host computer. Firmware updates can also be made using PCS.

PCS is used for setup and adjustment of PVCA 452 A/V functions. For information on accessing PCS, see the PVCA 452 User Guide (available at www.extron.com). For configuration details, see the embedder help file in PCS.
For Global Configurator Pro/Plus, see Configuring the PVCA 452 using Global Configurator below

NOTE : The factory configured password for this device has been set to the device serial number. Passwords are case sensitive. Performing a reset to factory defaults sets the password to Extron (see the PVCA 452 User Guide for reset instructions).

Configuring the PVCA 452 using Global Configurator

NOTE : The following are the most basic steps, outlined in the recommended order. For detailed instructions, see the Global Configurator Help File. The help file includes an introduction to the software, and instructions on starting a project.

Connect the host computer and the PVCA 452 to the same Ethernet subnetwork (see LAN port on page 4).
Start Global Configurator Pro/Plus (GCP) and open the Toolbelt feature (or use the stand-alone Toolbelt program).
Start Device Discovery, and select your PVCA 452 device from the list (use the MAC address to locate the desired device). Enter credentials, if required.
Use the Set IP feature in the Toolbelt software, or use the Toolbelt Manage > Network Settings tab to set the IP address or host name, subnet, gateway IP address, and related settings.
NOTE : If using a host name instead of an IP address, the user must enter a qualified host name (Username.HostName.Domain). For example: somename.somedomain.com
Using GC, create a new GC Plus or GC Professional project and configure the PVCA 452:
a. Configure the control ports.
b. Select device drivers and link them to each assigned serial, IR, or Ethernet port.
c. Configure settings (serial protocol, relay behavior, digital input, volume control settings) as needed.
d. Add and configure control interface (rebus, Touch Link Pro, etc.).
e. Set up monitors, schedules, macros, and local variables.
Save the project.
Build and upload the system configuration to the controller
