Mounting the Encoder

The encoder can be mounted in a 19” rack by attaching it to the ENC-

BRK1U encoder bracket that can be purchased separately. The bracket takes up only 1U of rack space and can hold 3 encoders.

Figure: ENC-BRK1U rack mountable bracket with 3 encoders.

The encoder can be attached to the bracket by lining up the four holes on the bottom of the encoder with the hole pattern on the bracket and screwing them together with the screws provided with the bracket.

Warning —

• If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room

• ambient. Ensure that the ambient temperature inside the rack does not exceed the maximum operating temperature of the encoder.

Ensure that sufficient airflow is provided in the

• rack environment such that safe operation of the equipment is not compromised.

Mounting of the equipment in the rack should be such that a hazardous condition is not created due to uneven mechanical loading.

Connecting Power

NOTE: Do not perform this procedure if Power over Ethernet (POE) is used.

If PoE is not available, the encoder needs to be powered through the removable power connector block. Refer to the diagrams in this guide for the location of the power connector block.

The device can be powered from 12 VDC or 24 VAC. The power consumption information is listed in the product specifications.

To connect power to the power connector block, complete the following steps:

1.

Remove the power connector block from the device.

2.

Remove the insulation from ¼” (6 mm) of the power wires.

Do not nick or damage the wires.

3.

Insert the two power wires into the two terminals on the power connector block. The connection can be made with either polarity.

Use a small slotted (5/64” or 2 mm blade width) screwdriver to loosen and tighten the terminals.

4.

Attach the power connector block back into the receptacle on the device.

Warning —

• Only power the encoder using a Class 2 power supply that is UL Listed, CSA approved, or bears the

CE mark. Never connect the encoder directly to mains power.

• In installations where multiple encoders are powered from the same power supply, ensure that the power supply, wiring, and all connections are rated for the total power required by all the encoders on the circuit.

When you select the wire used to provide power, be sure to select a gauge that is heavy enough for the wiring distance. Refer to the following table for the maximum wire length for different wire gauges.

Connecting Analog Cameras to the Encoder

Connect analog video cameras to the encoder using the coax/BNC connector video inputs on the front of the encoder. The encoder supports 4 video inputs and is initially configured for a composite video input with 75 ohm termination. The video standard (NTSC/PAL) is automatically detected. The video input status LEDs will turn on if the encoder locks to the video signal. If the video source is connected in parallel with other equipment, the input termination should be turned off, this can be done through the Avigilon Control Center software.

Connecting to the Network Video Recorder

Important: To avoid networking problems, only use network switches recommended by Avigilon.

Connect the encoder to the same network as the server running the

Avigilon Control Center software. An IP address is automatically assigned to the device, and will be detected by the software. For more

6

information on how to configure the connection, see the software user guide.

The connection status LEDs show the progress in connecting to the server and are described in the following table.

IP Address Selection

Once connected to a network, the encoder will attempt to locate and obtain an IP address from a DHCP server. If this fails, an IP address will be selected using Zeroconf (APIPA).

If the IP address is set using Zeroconf, the IP address will be in the

169.254.* subnet. A static IP address can be set from the Avigilon

Control Center software, consult the software user guide for details.

Advanced Features

Upgrading the Firmware

The firmware can be field-upgraded through the Avigilon Control

Center software. Consult the software user guide for details on how firmware upgrades are performed.

It is possible for the firmware to become corrupted during an upgrade

— for example, if power is lost during the upgrade process. If this occurs, the encoder can be reverted to run from bootstrap firmware.

Once reverted, it can be upgraded as usual.

Warning — Only revert to bootstrap firmware if the device is unable to start up due to corrupted firmware.

Firmware Revert Button

Figure: Firmware revert microswitch location on the rear of the encoder

1.

Disconnect power from the encoder.

2.

Using a straightened paperclip or similar tool, gently press and hold the firmware revert microswitch.

3.

While continuing to hold the microswitch, power the device. Release the microswitch after three seconds.

Caution — Do not apply excessive force. Inserting the tool too far will damage the device.
