xCOAX4-SET A set of active converters for Ethernet and PoE transmission via coax

xCOAX4-SET is a set of active converters for Ethernet data and PoE power transmission over coaxial cable used in analogue surveillance. The set allows the installation of cameras or other IP PoE devices in places where the replacement of the existing cabling is impossible or uneconomical.

The primary application of the xCOAX4-SET converters is the installation of PoE IP cameras via the coaxial cables used in analogue installations.

xCOAX4-SW module is powered from any PoE switch (RJ45 port) and, via the coaxial cable, enables bi-directional network communication and powering of the xCOAX4-CAM module. An IP camera or any network device can be connected to the RJ45 port of the xCOAX4-CAM module at the end of the line.

Using a coaxial cable, we can achieve a transmission range of:

• up to 1000m for 10Mbps throughput
• up to 500m for 100Mbps throughput

The maximum distance of data transmission and PoE power supply depends on the length and cross-section of the cables used and the quality of the BNC connectors used. The presence of other cables in the cable route and additional intermediate connections have a large impact on the stability of transmission. The maximum length of a coaxial cable is 1000m. In the case of poor cable quality, the transmission speed may be reduced to 10Mbps, which will be signalled by the 10M LED lighting up at the network connector.

Transmission, bandwidth and voltage control are indicated by LEDs:

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

LV LED snaps on and indicates a voltage drop below 44V DC on the XCOAX-CAM receiver. It can be reset by removing and re-applying power. Its lighting signals the need to verify that the power supply to the set is correct. A voltage drop below 44V DC may be the cause of unstable operation or will prevent PoE receivers connected to the XCOAX-CAM from starting up after restart.

xCOAX4-SET modules are capable of being powered from external power supplies via additional POWER screw connectors. For correct power supply to PoE receivers, the voltage must be higher than 44V.

Key features and functions:

• ethernet transmission via coaxial cable
• transmission at the level of 100Mbps up to 500m and 10Mbps up to 1000m
• power supply from a PoE switch in 802.3af, 802.3at or PoE passive standard (PoE IN port)
• clear signalling of operation, throughput and transmission status.
• small size of the device enabling installation in small spaces, e.g.: in a camera base
• low power consumption of the device (< 1.35W)
• easy and quick start-up without configuring 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.

xCOAX4-SET is equipped with a universal mounting base, which allows mounting in several ways:

• using the mounting studs on the 10.8mm grid, as found in all ABOX enclosures
• using mounting studs for 19‘ and 10’ rack adapters
• by screwing through the additional holes to any flat surface
• using additional adapter ADD-TH35 it is possible to mount the module on the TH35 rail (DIN)

Installation notes

• If a connection could not be established, verify the quality of the BNC connectors at the ends of the XCOAX path. Additional connections and branches of the XCOAX path may prevent stable transmission. Verify their correctness and remove any unnecessary ones.
• The bandwidth of the device is set automatically depending on the stability of the connection.
