Time Code Based NTP Time Server

The ES-289E provides a practical method of putting accurate time information onto a network. The unit reads ESE or SMPTE/EBU time codes. The NTP output is provided on a 10/100 Base-T Ethernet connector. The ES-289E is housed in a rugged black anodized desktop enclosure. A voltage-controlled temperature-compensated crystal oscillator is used to maintain the accuracy of the time code outputs when lock is lost.

The ES-289E is an IPV4/IPV6 compatible NTP Time Server. NTP clients can authenticate the NTP server with MD5 or SHA1 Symmetric Key Authentication. SNMP V1, V2 and V3 support allows specified users to be notified if a cold boot occurs, if Time Code Lock is lost or gained, or if NTP Authentication failed. The web server of the ES-289E can operate in two modes: HTTP or HTTPS. The HTTPS mode has the advantage of all information going to and coming from the server being encrypted.
