1. Introduction
NTP (Network Time Protocol) is a highly-precise and convenient way to transfer time via the
network. NTP time source is available for free on the Internet, or can be bought for
independent use.
POE (Power Over Ethernet) utilizes the technology that delivers DC power to Ethernet
connected devices. POE enables data and power transfer simultaneously through one
standard network cable, which makes the deployment of network equipment more
cost-effective.
GTD368 of GlobalTime brings together all the advantages of PoE technology and real-time
synchronized system to the market: get precise time source from the Internet, and receive
data and power over the same set of wires, which
guarantees high precision and low cost.
Moreover, GTD368 double-sided display is available. With an extra screen( rather than an
extra GTD368 device), the double-sided display effect is achieved. This innovation facilitates
installation and reduces costs.
