The NVT Model NV-EC1701 Ethernet over Coax EoC Transceiver is a compact media converter
that allows 10/100 BaseT Ethernet and PoE+ power to be transmitted using coax cable. These devices are often used in legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. 48 or 56 VDC class 2 power is delivered to one transceiver, which distributes it to up to four remote transceivers, and their PoE or PoE+ or High Power PoE cameras*.
These transceivers are extremely simple to use, with no IP or MAC addressing required. Status LEDs indicate power and link connectivity/activity for RJ45 and BNC ports. They are backed by NVT’s award winning customer support and limited lifetime warranty.
*Distance and number of devices supported will often be lower due to power delivery voltage-drop on the wire. See Wire Distance Chart on pages 8 & 9.

CONFIGURATION INSTRUCTIONS
NV-EC1701 EoC transceivers transmit high bandwidth encrypted Ethernet signals over conventional coax cables. To provide utmost signal integrity and security, the NV-EC1701 transceivers must be configured to communicate exclusively with other transceivers within their Network Group. This group typically consists of one NV-EC1701 located at the control room (usually connected to an ethernet switch or router), and up to four remote NV-EC1701 transceivers (usually connected to IP cameras).
Before connecting to the network, each NV-EC1701 must learn which other NV-EC1701 transceivers are to be part of that group. This simple process is called Joining. It is recommended that transceivers in each Network Group be configured prior to deployment using these instructions:
Step One: Gather Materials |
|
|
|
• NV-EC1701 transceivers |
|
|
|
• 48VDC power supply & line-cord (NV-PS48-60W) |
Step One: Gather Materials |
||
• Coax jumper |
|
|
|
• Small paper-clip, partially straightened |
|
|
|
• Device labels |
|
|
|
• IP Network Documentation Log |
|
|
|
Step Two: Connect Hardware |
|
|
|
• Remove and discard the “Configure Before Use” labels. |
|
|
|
|
|
|
|
• Connect two NV-EC1701 transceivers using a coax jumper. |
|
|
Connect |
• Connect a 48-56V power supply to transceiver #1; Apply power. |
|
|
|
|
|
Step Two: Remove Label Hardware |
|
• Verify that the blue POWER LED on each transceiver illuminates. |
|
|
|
|
|
||
|
|
|
|
•After 20 seconds, verify that the green BNC LED on each transceiver is off. If a BNC LED is on, the transceiver has been previously joined. Perform the un-joining process below before proceeding.
Step Three: Joining
•On transceiver #1, using the straightened paper-clip, momentarily depress the small push-button located behind and slightly above the RJ45 LED. The blue Power LED will begin blinking.
•Depress the same push-button on the transceiver #2.
•Both transceivers have now entered Join Mode.They will find each other and establish encrypted communication. In about 10 seconds, the blue Power LEDs on both transceivers will return to a steady on condition, indicating a successful Join.
Step Four: Adding Transceivers (if required)
•Disconnect transceiver #2 and replace it with a new un-joined transceiver (#3, or #4, or #5).
•Repeat steps two and three to add additional transceivers to the same Network Group.
Step Five: Documentation
•Label the configured transceivers with a unique Network Group ID of your choice. This will help you identify them after they have been deployed.
•Record this Network Group information in your IP Network Documentation Log. This log may include essential documentation which will help you identify all system devices during and after deployment:
• Camera Number |
• Camera-end NVT Transceiver MAC Address |
|
• Camera Position/Location |
• NVT Transceiver Network Group Name |
|
• Camera Make & Model |
• Control Room NVT Transceiver MAC Address |
Step Three: Transparent |
• Camera MAC & IP Address |
• Control Room Router Port Number |
view of push-button location |
• Camera Login & Password |
|
|
|
|
Un-Joining a Transceiver
If you need to move a transceiver from one Network Group to another, it must first un-learn its previous
Network Group and be returned to an un-joined state. Do this by:
•Connect a 48-56 VDC power supply to a transceiver to be un-joined.
•Wait until its green BNC LED is lit.
•Using the straightened paper-clip, momentarily depress the small push-button located behind
and slightly above the RJ45 LED until the green BNC LED goes off. The RJ45 LED should remain off.
•Release the paperclip.
• Observe that the BNC and RJ45 LEDs flash. |
|
Step Five: Transceiver MAC address |
|
•Observe that the BNC and RJ45 LEDs turn off.
•Observe that the BNC goes on solid.
•Un-joining is now complete.
If you are not sure that un-joining has been successful, remove and then re-apply power, and repeat.

LAN/WAN
Most installations that use the NV-EC1701 transceiver involve the replacement of an analog camera with an IP camera, while reusing the installed coax cable. Since most IP cameras support PoE (Power over Ethernet), the legacy 24VAC distribution may no longer be needed.
Disconnect all analog equipment from the coax before installing the IP equipment. The NV-EC1701 uses the coax to deliver 48 or 56VDC. To prevent damage, never connect analog cameras or analog control-room equipment to an NV-EC1701.
Transceiver Configuration
NVT EoC transceivers must be configured to communicate exclusively with other transceivers within their Network Group. The configuration process is described on page 3.
Connecting the Camera End
Install the new IP camera. Mount the NV-EC1701 nearby. Connect an RJ45 patch cable between the network connector (PoE) of the camera and the RJ45 jack on the NV-EC1701. Connect the coax to the BNC jack on the NV-EC1701.
For most installations, the IP camera power will be low enough, and the coax distance short enough, so that the IP camera and its NV-EC1701 can receive power through the coax. In most cases, a power supply will not be needed at this end. For additional details, see “High Power Extended Distance Considerations” on page 7.
Connecting the Control-room End
Install a second NV-EC1701 at the control-room end of the coax cable.
If rack-mounting is desired, use the NV-RMEC16 tray, which supports up to four NV-EC1701 transceivers, which together can support up to 16 cameras.
Connect the coax cable to the BNC jack on the NV-EC1701.
Connect a class 2 (SELV) 48V or 56VDC power supply to the power jack on the NV-EC1701. This will provide power to the entire system, including the cameras. The Blue “Power” LEDs will illuminate on both transceivers.
Connect an RJ45 patch-cord between the RJ45 jack on the NV-EC1701 and either: 1) an IP camera video input on a Hybrid DVR, or 2) an Ethernet switch allocated for video. See “Hybrid DVR Considerations” on page 5, or “NVR Considerations” on page 6.
The Green LEDs will illuminate when a network link is established, and will blink when data traffic is present.
MULTIPLE CAMERAS
The NV-EC1701 communicates via the coax using a bus-architecture. This means that up to four remote camera-end NV-EC1701s may be connected together to a fifth NV-EC1701 at the
control-room. The coax cables are connected
NV-BNCT
together using BNC splitters, available from NVT, or elsewhere. If you purchase BNC “T” connectors from another supplier, please purchase high quality connectors. Low cost connectors have been found to have intermittent shield connections.
Multiple IP cameras draw more current. To ensure
adequate power, see “High Power Extended
NV-EC4BNCT
Distance Considerations” on page 7.
PoE CONSIDERATIONS
The NV-EC1701 transceiver has been recently updated to support full PoE, PoE+, or High-Power cameras, as well as nonpowered legacy devices.
Unlike conventional PoE, voltage-drop and load current must be confirmed by the installer. See “High Power Extended Distance Considerations” on page 7.
NVT’s Class 2 current limiting ensures safety of the installation during fault conditions, while delivering higher power (up to 90 watts) with more efficient allocation amongst loads. Up to two power supplies may be used within a network group.

Figure 2 - Hybrid DVR Installation
TRANSCEIVER-TO-TRANSCEIVER HYBRID DVR ARCHITECTURE
The NV-EC1701 transceivers provide transparent end-to-end 10baseT or 100-BaseT connectivity with auto detection and autocrossover. This means that IP cameras or other devices may be installed at one end, and their data is transparently delivered to the other end. Before installing, transceivers must be configured per the instructions on page 3.
Long coax distances are supported, although local power may be required for extended distances. See pages 7 - 9.
The NV-EC1701 supports TCP/IP, UDP, HTTP, Multi-cast, and other standard protocols. This allows for the transmission of other network traffic besides streaming video.
The NV-EC1701 is network transparent, and operates in virtually every network environment, including support for Hybrid DVRs. These DVRs have some BNC ports for analog cameras, and some RJ45 ports for IP cameras. The RJ45 “video in” port is the connection point for the NV-EC1701. See figure 2.
By deploying a Hybrid DVR, with its dedicated IP camera port(s), the network is robust and secure, with none of the traffic, hacking, or virus vulnerabilities associated with PC-like hardware on an open LAN.
Depending on the Hybrid DVR, more than one camera may be connected to its IP camera port. Check the Hybrid DVR manual for details.
