Brandywine NTD-4106R NTP Internet Synchronized 4" Red LED Wall Clock Ethernet [Refurbished]
( 363054186766) )
New Open Box • Old Stock • Never Deployed • MINT- Cosmetic Condition • Large 4" Red LED • TCP/IP Network Clock • Time Sync via IP over LAN or Ethernet
Item is new old stock in mint- cosmetic condition. It has been tested to confirm that it works as it should. The IP address setting is shown on the display at power up. The username and password are the default values - BRANDYWINE:BRANDYWINE. An internal web server allows you to configure the unit - see screenshots taken during testing below. This clock does not have a GPS receiver, it obtains time from NTP servers accessed via the ethernet connection.

The Brandywine Communications Network Time Displays (NTD) purpose is to display time with accuracy. The NTD uses a Proportional Integral (PI) algorithm to set/synchronize its clock once and control its internal clocks with a reference. The most references are NTP Time Server and/or Serial Port Input.
When the NTD connects to the reference, the NTD will resynchronize its time and internal clocks with the reference's time. Using a closed loop control system, the NTD will correct its clocks based on the time difference between its internal clocks and the reference. A second order digital phase lock loop (PLL) is used to adjust the internal clocks of the NTD to match the time of the reference over long time intervals.
The Network Time Display may receive its input from two references.
- Network Time Display may receive time from the NTP Time Server through the Ethernet. To receive time from the NTP Time Server, connect one end of an Ethernet cable to the NTD Ethernet and connect the other end of the Ethernet cable to a hub.
- The Network Time Display may receive time from the Serial Port Input through the Serial Port. To receive time from the Serial Port Input, connect one end of a Serial cable to the NTD Serial Port and connect the other end of the Serial cable to the serial port of a computer or modem.
The Network Time Display may output its time through the Serial Port. To output its time through the Serial Port, connect one end of the Serial cable to the NTD Serial Port and connect the other end of the Serial cable to the serial port of the computer. Using a communications program such as HyperTerminal the user may output the time of the NTD to the display terminal.
