ETH-2wire-A-SET Set for 10/100Mbps LAN + PoE transmission over 2 wires

ETH-2wire-A-SET is a set of active converters for Ethernet data and PoE power transmission using 2 wires such as one pair of twisted pair UTP cable. The set allows the installation of cameras or other IP PoE devices in places where it is impossible or uneconomical to replace the existing cabling.

Basic applications:

• installation of IP PoE cameras in place of existing analog cameras
• for LAN + PoE transmission using UTP cable in which some of the wires have been mechanically damaged
• replacement of an intercom with an IP video intercom
• use of existing telephone cable for Ethernet data transmission
• installation of VOIP phones on the existing telephone wiring

ETH-2wire-A-TX transmitter is powered from any PoE switch (RJ45 port), and then using 2 wires, allows two-way network communication and powering the ETH-2wire-A-RX receiver along with the IP PoE camera. The LAN output port operates under the 802.3af/at/bt standard.

Using a single pair of UTP cable, we can achieve a transmission range:

• up to 800m for 10Mbps throughput
• up to 300m for 100Mbps throughput

The throughput of the 2wire path is set automatically depending on the stability of the connection. Throughput reduced to 10Mbps is indicated by switching on an additional 10M LED at the network connector. It allows quick diagnostics of the connection status.

For cables other than twisted-pair UTP, the maximum range and throughput may differ from those specified. Factors such as the quality of the cable, the number of connectors in the cable run, insulation damage, and environmental conditions present at the installation site may affect the actual transmission distance and should be taken into account when designing.

Transmission, bandwidth and voltage control are indicated by LEDs:

• PWR - The device is powered
• LED LINK - Signaling transmission between modules
• LED 10M - Available bandwidth is 10Mbps
• LED LV - Low voltage, low voltage (<44V) on the device

LV LED latches and indicates a voltage drop below 44V DC on the ETH-2wire-A-RX receiver. It can be reset by turning off the device and applying power again. Its lighting signals the need to verify the correctness of the power supply to the set. A voltage drop below 44V DC may be the cause of unstable operation or will prevent PoE receivers connected to the ETH-2wire-A-RX from starting up after restart.

ETH-2wire-A-SET modules have the ability to be powered from external power supplies via additional POWER screw connectors. For proper power supply of PoE receivers, the voltage must be higher than 44V.

Key features and function:

• Ethernet transmission capability over any 2 wires of the cable
• transmission at 100Mbps up to 300m and 10Mbps up to 800m over UTP cable wires
• ability to be powered by PoE switch in 802.3af, 802.3at or PoE Passive standard (PoE IN port)
• clear signaling of operation status, throughput and transmission
• small size of the device allowing installation in small spaces, e.g.: in the base of the camera
• low power consumption of the device (< 1.35W)
• easy and quick startup without configuration of parameters
• wide operating temperature range

The device has a protection level of IP20, a suitable enclosure (minimum IP44) is required to ensure protection from the elements and condensation.

If the device will be used in a small space, it is possible to cut and break the mounting brackets of the base to reduce the dimensions of the module.

ETH-2wire-A-SET comes with a universal mounting base that allows mounting in several ways:

• with the use of mounting studs on the 10.8mm raster, which is in all ABOX enclosures
• with the use of mounting studs for RACK 19“ and RACK 10” adapters
• by screwing through additional holes to any flat surface
• using additional ADD-TH35 adapter you can mount the module on TH35 (DIN) rail

Installation notes

• The throughput values and distances given are for a single pair of wires of UTP cable, in reality they may vary depending on the cable used on the 2wire track.
• The bandwidth of the 2wire path is set automatically depending on the stability of the connection.
• Transmission and power is transmitted through the DATA connector, the POWER connector should only be used for power from an external power supply
• The modules are connected by a pair of wires using DATA connectors, which transmits both data and power.
