GPS Reference• The Global Positioning System (GPS) is a U.S. space-based global navigation satellite system. It provides reliable positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night, anywhere on or near the Planet Earth.• Masterclock devices use the timing information available from GPS system signals to provide the most accurate time for synchronization purposes.

Accurate time begins with GPS.

5

Time Code (SMPTE/IRIG)• Time code is a low power audio signal similar to the signal of a modem that contains time and date information.• Signal can be transmitted over inexpensive coaxial cable and wiring such as telephone pairs.• With the proper distribution amplifiers, time code can be sent over long distances and connected in parallel to hundreds of clocks and other devices.

Provides reliable distribution of time and date.

6

Network Time Protocol (NTP)

• NTP is an open standard Internet protocol that utilizes standard Ethernet wiring to transfer time and date information.• Configure the clocks from any computer on the network with Masterclock’s proprietary WinDiscovery software.• Source can be either a local time server or an offsite reference, such as GPS or Time Code.• NTP clocks can utilize Power over Ethernet (PoE).

Our most versatile form of timing distribution.

7

Power over Ethernet (PoE)

• PoE clocks receive power and time reference data from 1 cable, saving installation costs.• Signal can be transmitted over existing LAN and WAN wired networks and over various wireless system.• Power several PoE clocks and devices from a single PoE switch instead of dedicated power supplies.

One cable. Saves time and costs.

Digital Displays• All digital displays use seven-segment LEDs

• Compared to LCDs, LEDs offer superior viewing angles, significantly better shock and vibration performance and a life that is 100’s of times longer.

• Display colors available in red, blue, green, amber, or white.• Adjustable brightness levels.• Solid steel case with powder coat finish that resists corrosion.• Battery-backed real time clock chip in case of loss of time reference or power.

High visibility. Sleek design.

Classic Timing Displays

12

Digital-Analog Displays• 4-digit LED display of hours and minutes accompanied by simultaneous analog LED display of seconds. • Display colors available in red, green, blue, amber, or white.• Customize display to with and color combination.• Adjustable brightness levels.• Visibility: 100 feet (30 meters)

13

NTP100 Series• The NTP100 Series of time servers generate accurate time and date signals for NTP clocks and your network. • Can synchronize to atomic clock in GPS satellites, a time code source, or generate time via an internal crystal oscillator.• Maintain timing accuracy when GPS or Time Code signal is lost with an internal battery-backed real-time clock chip.• Optional high-stability oscillators provide holdover stability to 1 ppb/day (±250ms/year)

NTP Time Servers

14

GMR Series• One GMR Series master clock device can support and synchronize hundreds of thousands of NTP clocks.• Can read NMEA and NENA messages to set its system time, or time can be set manually, and it can generate NMEA, NENA or Truetime/Kinemetrics.• Optional outputs include Time Code (SMPTE, IRIG-A, B and E), PPO (Programmable Pulse Output), PPS (pulse-per-second), 10 MHz sine wave, and IEEE 1588 Precise Time Protocol.

Configurable Master Clock Generators

GMR5000 Master Clock

15

PCI and PCIe Cards

• Provides millisecond accuracy to Windows applications. • Reference GPS, Time Code, or generate time via an internal crystal oscillator.• PCI available for all card sizes, full- and half-height brackets available.• High-stability oscillator options increase holdover accuracy to up to ±250ms/year. 

Time Code Readers, GPS Receivers, and Internal Oscillators for PC or Network

TestimonialsExtensive renovations at Estádio do Maracanã in Rio De Janeiro for the 2014 World Cup included installation of Masterclock digital clocks throughout the stadium.

The Scoreboard Operations Department of the Florida Marlins and Miami Dolphins recently installed a number of Masterclock NTP clocks in their stadium operations. Shown below is a Blue NTD86 that displays both NTP and game time from the scoring systems.
