ED406-101-4D-N1-NTP

Bright, easy-to-see LED clocks. These models are available in sizes from 2.25" and 4.0" (Bar Segment) to 6", 8", 12" and 18" high (Dot Matrix). The standard model is avaialble in HH:MM format. A six-digit model (HH:MM:SS) model is available also.

The ethernet interface allows the clock to be connected to a computer network. Network Time Protocol (NTP). 

NTP is a uniform method of sending time over a computer network. By default, the clock will act as a client to public or local NTP time servers. The clock can also be configured to receive NTP broadcasts. NTP provides Universal Coordinated Time (UTC) to the clock. The clock implements offsets and daylight saving rules to display the correct local time.

Once the LED clock is connected to the network and power is applied, DHCP is used to automatically assign each clock an IP address on the network. Then, each LED clock will search the Internet or local area network for time servers. 

The control software included with the clock, and available for download from the EDI web site, may be used to assign IP addresses for local time servers. Up to 10 local time servers may be assigned. Once all clocks are attached to the network and operating, simply send a command from the PC clock control program to assign a new local time server IP address. The new IP address will be assigned to all clocks on the subnet simultaneously.

The clocks will immediately begin using the new local time server.
An RJ-45 ethernet jack is included for connecting to the ethernet network cable. Standard 10 BASE-T half-duplex Ethernet is supported.

Standalone ethernet NTP (Network Time Protocol) Client. This option does not require a PC. A standalone unit that connects to the ethernet. This will periodically request the time via NTP over Ethernet. The NTP server can reside locally or over the internet.
