Due to communication speed limitations it is recommended thattemplate distribution is only performed on TCP/IP networks.2.4.12.4.12.4.12.4.1 TCP/IPTCP/IPTCP/IPTCP/IPDIGIgarde PLUS is supplied with a connected and configured PoE-capable RJ45socket (for PIN assignments, see Table 6).Power over Ethernet (PoE) extends the functionality of Ethernet by supplyingreliable DC power over the same Category 5/5e twisted-pair cable that currentlycarries Ethernet data. PoE can supply reliable power to low power Ethernetnetwork devices such as wireless access points (WAP) and security cameras.To use PoE to power the DIGIgarde PLUS, you must connect the unit to a PoE-enabled network device such as an Ethernet switch. Alternatively, power can beinjected into the cable from a midspan power supply or PoE injector.Table 6 shows the Ethernet RJ45 connector pin assignments for the DIGIgardePLUS. Pins 4&5 provide the DC supply with pins 7&8 being the GND connections.Data is communicated on pins 1&2 and pins 3&6.Table 6 Ethernet RJ-45 connector pin number (From left to right)Number Wire Colour Purpose1 White/Orange TX+2 Orange TX-3 White/Green RX+4 Blue Power5 White/Blue Power6 Green RX-7 White/Brown GND8 Brown GNDCAUTION! It is strongly recommended that if the reader is connected to anaccess control unit it is also powered from this to prevent damage resultingfrom any difference in earth potentials.
