Time might be on your side, but it waits for no one, and though you can keep it, time will often get away from you. PoE simplifies installation and reduces installation costs.Time is both a tyrant and a teacher. A mains spur is not required where the clock is located. PoE allows clocks to be installed with only a single data cable required to be run to the clock. All models are Power-over-Ethernet (PoE) devices. Each clock has a RJ45 network connector at the rear. The slave clocks connect to a master over an IP Ethernet network. The analog clock is available with a 300 mm (12 inch) clock face. The digital display models have 100mm (4 inch) high digits, viewable from up to 50 m. Available in 4 and 6 digit and analog models.
TimeTools have a range of slave clocks that synchronize to a master clock using the NTP protocol. The T550 also has a high-precision TCXO oscillator to maintain accurate time in the event of loss of satellite signals. The device can receive timing information from multiple satellite systems – GPS, GLONASS, Beidou and Galileo. The T550 is a dual LAN, Multi-GNSS master clock with TCXO oscillator. The T300 GPS master time clock is housed in a 1U high, rack-mountable enclosure. TimeTools T100 is a low-cost, high-performance master clock housed in a compact enclosure. They can also be used to synchronize servers, workstations and network infrastructure. They synchronize slave clocks using the Network Time Protocol (NTP) over an IP Ethernet network. TimeTools has a range of GPS and Multi-GNSS referenced master clock models. They are generally regarded as superior sources of time. Satellite time references are more accurate than radio sources and can be received globally. The WWVB transmitter is located in Colorado and serves the North American continent. The DCF-77 transmitter is located in Frankfurt, Germany, and serves much of Western and Central Europe. The MSF signal is operated for the UK government and is available throughout the UK and Western Europe. Radio time references are often constrained by national boundaries.
While Galileo is the new civilian satellite based navigation and timing system operated by the European Union, due to be fully operational by 2019. GLONASS is a similar service operated by the Russian government. The GPS system is operated by the US government, it is a subscription-free system that provides global navigation and timing services. These time references can be used by master clock systems as a source of accurate time. While national time references are often radio based – such as MSF (UK), DCF (Germany) and WWVB (USA). Global time references are generally satellite based – such as GPS, GLONASS and Galileo. There are a number of global and national hardware clock references. No mains spur is required where clocks are located – significantly lowering installation costs. PoE provides both data and power on a single standard ethernet cable. Additionally, Power-over-Ethernet (PoE) has provided even more installation flexibility. Standard networking devices and infrastructure can be used for the network.Īll TimeTools master and slave clocks use Ethernet networking. It also allows much more flexibility of cabling installation. Ethernet networks allow clocks to be configured from a central point using a standard PC. The latest clocks utilize IP based ethernet networking. Timing information is broadcast along a 2 or 4 core cable to clocks that are usually daisy-chained.
#MASTER CLOCKMAKER SERIAL#
Serial clocks utilize a RS422 or RS485 transmission system.
#MASTER CLOCKMAKER DRIVER#
Impulse driver has generally been superseded by serial or Ethernet network clocks. Originally, many master clock systems used an impulses generated by the master clock to advance and synchronize slave clocks. The clock network can either be a simple wired serial network, a wired pulse signal or a more complex Ethernet network. Slave clocks typically communicate on a clock network. A number of slave clocks synchronize with a master clock to provide a display of accurate time. Typically, the master time clock maintains accurate time from a hardware clock source, such as GPS, GLONASS, Galileo or other sources of precise time.Ī slave clock is a hardware device that typically depends on a master clock to for accurate time. A master clock is an electronic device that provides time synchronization signals to a number of slave clocks on a network.
