POE PTP/NTP DISPLAY CLOCK 4 INCH 4 DIGIT

The PoE displays require a connection to a PoE (Power over Ethernet) enabled LAN (Local Area Network) through a Cat5 Ethernet cable. The power for these clocks is managed through the LAN with either a PoE switch, or a PoE injector. Ask your IT specialist if your have a powered LAN, as there is no other way to provide power to these units. If you do not have a PoE enabled LAN, then you can purchase a PoE injector from TimeMachines as an accessory.
