Document Information
ix
To help ensure safety and to help reduce risk of injury or damage, observe the following:
Warning:
1. Only qualified trained personnel should service and repair this equipment.
2. Observe local codes and laws and ensure that installation and operation are in
accordance with fire, security and safety standards.
Electrical Safety Notice and Warnings
Warning:
1. Read the installation instructions before you connect the unit to a power source.
2. Electrical safety should always be observed. All electrical connections must be
performed by a certified electrician.
3. Use the supplied power supply and protect against static electricity, ground
faults and power surges.
4. If you use an extension cord with this system, make sure that the total ampere rating
on the products plugged into the extension cord does not exceed the extension cord
ampere rating.
5. To avoid possible shock hazards or damaging the unit, assure that the positive and
negative of the power leads are properly connected to the terminal block connector
before plugging it into the unit or turning on the power source.
6. In the following situations, turn off the electric power immediately and appropriate
repairs, replacements or remedies should be taken if:
The power line or plug is damaged, frayed or shows heavy wear.
The unit has been physically crushed or deformed.
The unit has been exposed to water.
The unit has been exposed to, or shows signs of damage from, fire,
intense heat, heavy smoke, fumes, or vapors.
Electrical connections of the unit become abnormally hot or generate smoke.
The unit has been dropped, damaged or shows signs of loose internal parts.
The unit does not operate properly.
7. Failure to follow proper procedures may cause permanent damage to the unit and
may void the product warranty.
Warning:
The unit contains a lithium battery. There is a risk of severe injury if the battery is replaced
by an incorrect type. Dispose of used batteries according to instructions.

EN-216 User and Installation Guide

Caution:
To avoid damage from overheating or unit failure, assure that there is sufficient temperature
regulation to support the unit’s requirements. Operating temperature should be kept in the
range -10° to 55°C (14° to 131°F), with no more than 90% non-condensing humidity.
Minimizing EMI and RFI
When wires run for a significant distance in an electromagnetic field, electromagnetic interference (EMI)
can occur. Strong EMI (e.g. lightning or radio transmitters) can destroy the units and can pose an electrical
hazard by conducting power through lines and into the system. Poor quality or worn wiring can result in
radio frequency interference (RFI). To minimize the effects of EMI and RFI, consult your reseller.
Site Preparation
There are several requirements that should be properly addressed prior to installation at the site. The
following specifications are requirements for proper installation and operation of the unit:
Ambient Environment Conditions: Avoid positioning the unit near heaters or heating system
outputs. Avoid exposure to direct sunlight. Use proper maintenance to ensure that the unit is free
from dust, dirt, smoke, particles, chemicals, smoke, water or water condensation, and exposure to
EMI.
Accessibility: The location used should allow easy access to unit connections and cables.
Safety: Cables and electrical cords should be routed in a manner that prevents safety hazards,
such as from tripping, wire fraying, overheating, etc. Ensure that nothing rests on the unit’s cables
or power cords.
Ample Air Circulation: Leave enough space around the unit to allow free air circulation.
Cabling Considerations: Units should be placed in locations that are optimal for the type
of video cabling used between the unit and the cameras and external devices. Using a
cable longer than the manufacturer’s specifications for optimal video signal may result in
degradation of color and video parameters.
Physical Security:The unit provides threat detection for physical security systems. In order to
ensure that the unit cannot be disabled or tampered with, the system should be installed with
security measures regarding physical access by trusted and un-trusted parties.
Network Security:The unit transmits over IP to security personnel for video surveillance. Proper
network security measures should be in place to assure networks remain operating and free from
malicious interference. The unit is intended for installation on the backbone of a trusted network.
Electrostatic Safeguards:The unit as well as other equipment connected to it (relay outputs,
alarm inputs, racks, carpeting, etc.) shall be properly grounded to prevent electrostatic discharge.
The physical installation of the unit is the first phase of making the unit operational in a security plan. The
goal is to physically place the unit, connect it to other devices in the system, and to establish network
connectivity.

Introduction
This User’s Guide is intended to help you physically install, configure settings for, and operate the EN-216
encoder. The EN-216 features 16 independent dual streams (video/audio and video-only) at a maximum
resolution of D1 up to 25/30 FPS (PAL/NTSC). The encoder supports H.264, MPEG-2, MPEG-4, and MJPEG
compression. It includes 16 alarm inputs and four relay outputs. Alarms and commands can be sent by
TCP/IP, HTTP, FTP, email, or SNMP. The unit is powered by a 12VDC supply.

4.2.1 Grounding the Unit
The unit must be grounded according to local regulations and codes.
To ground the unit
Loosen the screw of the grounding terminal located on rear panel of the unit. See Figure 1: EN-216
Front Panel (page 3).
Attach a properly rated ground cable to the grounding terminal. Make sure the ring/spade terminal
of the grounding cable is properly connected between the screw and rear panel. Tighten the screw.
Ensure that the other end of the ground cable is connected to a protective earth according to local
regulations and codes.
4.2.2 Connecting the Unit to the Power Supply
The unit is delivered with a 12VDC power supply.
Caution:
Before connecting to the power, review the Electrical Safety Notice and Warnings (page ix).
Warning:
1. To prevent bodily injury or damage to the unit, only use properly rated and approved
power supplies.
2. Make sure that the power supply connection matches the positive and negative polarity
on the unit.
3. Make sure that the power supply matches the required specifications. Electrical safety
should always be observed.
To power the unit with a DC power supply
Use the provided two-pin spring clamp terminal block connector to connect the positive and
negative leads on the DC power supply to the + and –terminals on the power input terminal block
on the unit’s rear panel. See Figure 2: EN-216 Rear Panel (page 4).
Power supply specifications:
Input: 100-240V, 50/60Hz, 1.7A
Output: +12VDC, ,3.33A
For more information on how to use the spring clamp connectors to connect the power lines, see
Connecting Leads to a Spring Clamp Terminal Block (page 96).
4.2.3 Connecting the Unit to the Network
By default, the unit is shipped with DHCP enabled.
If your network uses firewalls, you must configure them to support communication among the units and
computers running the Internet browser used to connect to the unit’s web interface. After connecting the
unit to the network, check that it can be found on the network as described in this section.
Note:
To view a summary of the network settings used by the encoder, see Network Settings (page 95).

Installing and Connecting the Encoder

To connect the unit to the network
Connect the encoder’s LAN port to the same subnet (VLAN) as the PC that is running the DVTEL
DNA configuration utility. See Figure 2: EN-216 Rear Panel (page 4).
Change the IP address according to your specific requirements. See the next section.
4.2.4 Configuring the Unit’s Initial IP Address
Use the DVTEL DNA utility to discover the unit on the network and to set the unit’s initial IP address.
If the encoder is managed by DVTEL’s Horizon VMS configured as a DHCP server, Horizon
automatically assigns the encoder an IP address. Verify that the encoder is configured with DHCP-
enabled.
If the encoder is managed by DVTEL’s Latitude VMS, you must manually enter its IP address in the
DNA utility.
Note:
1. It is possible to set the IP address without changing the subnet.
2. The unit and the PC must be physically connected on the same network segment.
3. The PC browser version must be 32-bit Internet Explorer (IE 7, 8 or 9).
To manage the encoder using Horizon or on a DHCP-enabled network
Insert the CD included in the package in your computer’s disk drive.
Run the dna.exe file by clicking the icon. The DNA application opens and the device is
displayed in the DNA Discovery window.
