The ES-911/TSM is a Stand-Alone (manually settable) Master Clock and Time Code Generator. The unit is specifically designed for a PSAP (Public Safety Answering Point) as a Master Clock and is capable of "Time Synchronizing" all components of a PSAP.

The unit displays six digits of time in either 12 or 24 Hour format and utilizes a Quartz timebase for high accuracy. Date information is also available on all time code outputs. The ES-911/TSM generates several types of time code - IRIG-B, IRIG-E, ESE, RS232C (both "Broadcast" and "Query" ports provided) and a 1PPS signal. These outputs allow the ES-911/TSM to synchronize and easily interface with equipment such as CAD, ANI / ALI Controllers, Voice Recorders and Radio Consoles that meet NENA Standards. The ES-911/TSM can also synchronize computers and other digital / analog clock systems.

Software is also supplied with the ES-911/TSM permitting the user to continuously update a computer's DOS or Windows clock to the time available on the "Broadcast" RS-232C output.
