ESE ES-188J NTP Referenced Master Clock/Time Code Generator with 220 VAC/50Hz

The ES-188 is an NTP referenced Master Clock and Time Code Generator. It displays nine digits (Day of Year, Hour, Minute & Second) of time as received via a user selected NTP server. Simultaneously, the ES-188 generates several types of time code including SMPTE LTC, ESE-TC89, ESE-TC90, ASCII (RS-232C & USB), EBU, IRIG-B and a 1PPS signal. These outputs allow the ES-188 to easily interface with new or existing computers, automation and clock systems. Option J is a 220 VAC/50 Hz Operation: The unit is configured to operate from 220 VAC line voltage. 117 VAC 50/60 Hz is standard.

Software supplied with the ES-188 permits users to continuously update a computer's Windows' clock to the time available on the USB port. Other features allow the user to select SMPTE mode (DF, NDF, EBU & Real Time), offset the Time Zone displayed and output by the ES-188 and advance or delay the time output for various synchronizing purposes.

A user may find the ES-188 particularly beneficial if: 1) The user has trouble getting a reliable GPS Signal into a facility, such as a basement or a building with metallic coating on the windows; 2) The user has trouble getting an antenna to the outside of a facility, because the cable run will be too expensive or the facility cannot be modified, which is the case with many historical buildings or 3) A facility needs to be time synchronized to a remote location through NTP, for example, universities with multiple campuses or NPR affiliate stations.
