The ES-185U/NTP from ESE is a GPS master clock and timecode generator that displays the day of year, hour, minute, and second in nine digits of UTC (Coordinated Universal Time), as received via the internal 12-channel GPS receiver. Simultaneously, it generates several types of timecode and an extremely accurate 1PPS signal (+/-10 ns). These outputs allow the unit to easily interface with a new or existing computer, automation, and clock systems. An Ethernet NTP (Network Time Protocol) port allows the clock to function as an NTP server and provides clock set-up via a LAN.
Included with the unit is an indoor/outdoor antenna which is connected via an included 16 ft cable. If additional cabling is required, you may also need a low-loss cable (LA-12F or LA-12FN), in-line amplifier, or antenna power supply (ES-AB1A) in extra long runs where more than one in-line amplifier is used. Please consult the ESE website for more information.
A software application is supplied that allows you to continuously update a computer's Windows clock to the time available on the USB port. Other features allow SMPTE mode selection (DF, NDF, EBU, or Real Time), Time Zone displayed/output offset, and time output advance/delay for various synchronizing purposes.
