The ES-911E/GPS/NTP is a GPS (Global Positioning System) Master Clock and Time Code Generator. The unit is specifically designed to meet the NENA (National Emergency Number Association) Standard NENA-04-002 for a PSAP (Public Safety Answering Point) Master Clock and is capable of Time Synchronizing all components of a PSAP. The unit displays six digits of time -- legally traceable to UTC (Universal Coordinated Time) as received via the internal 12-channel GPS receiver. Simultaneously the ES-911U/GPS/NTP generates several types of time code - IRIG-B and IRIG-E and ESE and RS232C (both Broadcast and Query ports provided) and a 1PPS signal. These outputs allow the ES-911U/GPS to synchronize and easily interface with equipment such as CAD and ANI / ALI Controllers and Voice Recorders and Radio Consoles that meet NENA Standards. The ES-911U/GPS/NTP can also synchronize computers and other digital / analog clock systems. The unit also features an Ethernet NTP port for network time synchronization. Included with the ES-911U/GPS/NTP is an indoor / outdoor antenna that is connected to the unit via the provided 16 ft. cable. If additional cable is required -- low-loss cable or an in-line amplifier (LA-12F or LA-12FN for low-loss cable) or for extra long cable runs where more than one in-line amplifier is used -- an Antenna Power Supply (ES-AB1) may be required. Consult the ESE factory for more information. Software is also supplied with the ES-911U/GPS/NTP permitting the user to continuously update a computers DOS or Windows clock to the GPS time available on the Broadcast RS-232C output.
