1.1. General description.
The EXT-POE4H extender is a device designed to increase the PoE and Ethernet range by additional 100 meters
using UTP Cat. 5 cable. The Extender can be powered using a another PoE-compliant device (PoE IN input) or an external
44-57 V DC power supply unit (DC IN input). The power source is selected using the Power Source jumper (see Fig. 1).
The output voltage and data are available at the PoE OUT1 and OUT2 outputs designed for connecting cameras or other
IP devices using PoE power supply. The maximum load current is 0,3 A (total =0,4 A max.). The PoE OUT1 and PoE
OUT2 ports are supplied over 4/5 (+) and 7/8 (-) pairs, which, according to the Ethernet standard, are not used for data
transmission (data transmission uses 1/2 and 3/6 twisted pairs).
This device cannot be used on Gigabit Ethernet networks, where all twisted pairs are involved in data
transmission.
