The ES-911/USB and ES-911/Serial are ESE Master Clocks that obtain Date and Time information from a PC's serial port (ES-911/Serial) or its "Universal Serial Bus" port (ES-911/USB). The units are specifically designed 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 of equipment such as CAD, ANI/ALI Controllers, Voice Recorders,and Radio Consoles. Both products can also synchronize other computers and digital/analog clock systems.

Using these units in conjunction with a network that is synchronized from the Global Positioning System (using the ES-911/GPS) allows highly accurate time to be distributed to all equipment within reach of a networked PC and a ES-911/USB or ES-911/Serial.
