Inputs - NTP Server
The master clock can receive NTP time over a Local Area Network connected to the Internet. To accomplish
this, the master clock must be connected to the router by a CAT5 or CAT6 Patch Cable with an RJ45
connector. The Ethernet port on the master clock can be identified using the diagram below.
Firewall Ports 80 and 123 must be open to use the master clock on a network.
The connection between the master clock and the router must be a wired connection. V-MCS-CD Master
Clocks do not include a wireless network card for WiFi routers.
