Here\'s a used, good condition ESE GPS disciplined clock whichhas the optional NTP server installed. The unit is in goodcosmetic condition and is fully working. After theusual initialization viaserial port, the unit syncs to GPS and shows the correctdate. A basic antenna is included toget you started but for optimal results you should ideally planon using an outdoor antenna (5V) with a full unobstructed viewof the sky. Theinternal lead acid back up battery is also new at the time oflisting, but its longevity cannot be guaranteed as it maydischarge between listing and eventual shipment. Replacementshowever are very affordable.

Note that you will most likely need the ESE PC-basedcontrolapplication, GPS32, (from their website, or I can email thebuyer a copy) to initializethe unit when you start testing, particularly if the unit hasnot been powered up for some time. Your PC should beconnected to the 25 pin RS-232 SETUP port on the rear panel, soyou may need a 9 pin/25 pin adapter if you only have aDB9straight through serial cable. Once the clock isrunning the internal backup battery should keep the GPS cardpowered and so it should not need re-initialization unless theunit is unpowered for a long time. The Ethernet portships set to thedefault setting of 192.168.1.50. To change this you need tofollow the Telnet based procedure documented in the manual(ie. \"TELNET 192.168.1.50 9999\" to bring up the config menu).

No unpictured cables, accessories or documents are included.No printed manual is included but a copy may be downloaded required.

The ES-911/GPS is a GPS Master Clock/Time Code Generator. Theunit is designed and built to meet or exceed all specificationsrecommended in the NENA (National Emergency Number Association)PSAP (Public Safety Answering Point) Master Clock Standard(NENA-04-002). The ES-911/GPS allows other equipment designed tomeet NENA specifications to be synced to the time information asreceived from the GPS satellites. Equipment not designed to theNENA specifications may require the ES-911/GPS to be modified oran ESE Time Code Converter.

The Master Clock receives legally traceable time and dateinformation from Global Positioning System satellites and suppliesUTC (Coordinated Universal Time) synchronized data to the user ina variety of forms. A twelve-channel receiver is employed that iscapable of tracking up to twelve (12) satellites simultaneously,although reception of only one is required for accurate time datato be output.

The ES-911 ESE Master Clock provides Date and Time informationfrom the GPS constellation. The units are specificallydesigned to provide all of the time codes as described in the NENA(National Emergency Number Association) Standard NENA-04-002.These units easily interface to and allow synchronization ofequipment such as CAD, ANI/ALI Controllers, Voice Recorders,andRadio Time Codes from Network Time
