1 Overview
1.1 Units Without GPS Receiver Option
The Brandywine Communications Network Time Device’s (NTV) purpose is to display time with
accuracy. The Network Time Device uses a Proportional Integral (PI) algorithm to set/synchronize
its clock once and control its internal clocks with a reference. The most used references are NTP
Time Server, Serial Port Input, and GPS (optional). When the Network Time Device connects to
the reference, the Network Time Device will resynchronize its time and internal clocks with the
reference’s time. Using a closed loop control system, the Network Time Device 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 Network Time Device to
match the time of the reference over long time intervals.
1.2 Units With GPS Receiver Option
The Brandywine Communication Network Time Device’s (NTV) purpose is to function as a network
time server for other devices (clients) on a computer network. A built-in GPS receiver receives
precise time signals from orbiting GPS satellites and uses these signals to synchronize the internal
clock of the Network Time Device. Using a closed loop control system, the Network Time Device
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 Network Time
Device to match the time of the reference over long time intervals.

2 Specifications
2.1 Inputs
The Network Time Device may receive its input from three references. The three references the
Network Time Device receives input from are the NTP Time Server, Serial Port Input, and GPS
(optional).
2.1.1 NTP Time Server
The Network Time Device 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 Network Time
Device Ethernet and connect the other end of the Ethernet cable to a hub.
2.1.2 Serial Port Input
The Network Time Device 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 Network Time
Device Serial Port and connect the other end of the serial cable to the serial port of a computer,
modem, or Brandywine Communications Master Clock.
2.1.3 GPS (Optional)
The Network Time Device may receive time from the GPS through the Antenna. To receive time
from the GPS satellites, connect the cable to the Network Time Device Antenna.

2.2 Outputs
The Network Time Device 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 Network Time Device Serial Port and
connect the other end of the serial cable to the serial port of the computer. OR connect one end of
the serial cable (1) to the Network Time Device Serial Port (1), connect the other end of the serial
cable (1) to the serial port of the modem (1), connect the modem (1) to another modem (2),
connect one end of another serial cable (2) to the serial port of the modem (2), and connect the
other end of the serial cable (2) to another Network Time Device Serial Port (2). Using a
communications program such as HyperTerminal the user may output the time of the Network
Time Device to the display terminal.

2.3 Button and Indicators
The Network Time Device has one button, the Brightness and three indicators, the Power, Link,
and Speed.
2.3.1 Brightness Button – Brightness, IP Address, and Test Mode (Rear Panel)
The Brightness button functions as the brightness button, IP address button, and test mode button.
The Network Time Device has eight levels of brightness. To increase the level of brightness, press
the Brightness button one time.
To display the IP address of the Network Time Device, press the Brightness button two times. Use
the same speed you would use to double click a mouse when pressing the Brightness button two
times.
To get to the test mode, press and hold down the Brightness button for more than a second and all
lights in the display window will glow. The test mode is useful because the user may test the lights
in the display window to see if all of them are currently working.

2.3.2 Brightness Button – Default Mode (Rear Panel)
To get to the default mode, press and hold down the Brightness button for more than ten seconds
and all lights in the display window will flicker. The default mode will default the unit’s memory to
factory default settings.
