Here's a used, good condition ESE GPS disciplined clock which
has the optional NTP server installed. The unit is in good
cosmetic condition and fully working - the photos show the
actual item for sale and the screenshot below features the
actual test results. The original Motorola M12+ GPS receiver has
been replaced with a $260 modern replacement from ublox which is
much quicker to achieve sync to GPS and which will provide an
accurate date beyond 2037. A basic antenna is included to
get you started but for optimal results you should ideally plan
on using an outdoor antenna (5V) with a full unobstructed view
of the sky. The internal coin cell battery which maintains
settings if the power is disconnected has been replaced by a
more substantial AA sized lithium battery which should provide
good service for a number of years into the future. The
internal lead acid back up battery is also new at the time of
listing, but its longevity cannot be guaranteed as it may
discharge between listing and eventual shipment. Replacements
however are very affordable.
Note that you may need the ESE PC-based control
application, GPS32, (from their website) to initialize
the unit when you start testing, particularly if the unit has
not been powered up for some time. Your PC should be
connected to the 25 pin RS-232 SETUP port on the rear panel, so
you may need a 9 pin/25 pin adapter if you only have a DB9
cable. The Ethernet port ships set to the
default setting of 192.168.1.50. To change this you need to
follow the Telnet based procedure documented in the manual
(ie. "TELNET 192.168.1.50 9999" to bring up the config menu)
as the web-based configuration screen is based on an obsolete
version of Java that is not supported in current browsers (the
screenshots shown below were obtained using IE11 under Windows
XP 32 Bit, which may not be convenient for the buyer to
replicate).
No unpictured cables, accessories or documents are included. No printed manual is included but a copy may be downloaded here (https://www.prostudioconnection.net/2606/ESE_ES-911_Manual.pdf) if required.
The ES-911/GPS is a GPS Master Clock/Time Code Generator. The unit is designed and built to meet or exceed all specifications recommended 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 to meet NENA specifications to be synced to the time information as received from the GPS satellites. Equipment not designed to the NENA specifications may require the ES-911/GPS to be modified or an ESE Time Code Converter.
The Master Clock receives legally traceable time and date
information from Global Positioning System satellites and supplies
UTC (Coordinated Universal Time) synchronized data to the user in
a variety of forms. A twelve-channel receiver is employed that is
capable of tracking up to twelve (12) satellites simultaneously,
although reception of only one is required for accurate time data
to be output.
The ES-911 ESE Master Clock provides Date and Time information from the GPS constellation. 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.
