ES-102U GPS Based Time Code Generator / Master Clock


The ES-102U is a low-cost yet very accurate GPS Master Clock/Time Code Generator. The unit receives time and date information from Global Positioning System satellites and supplies this data to the user in the form of four (4) different types of time code … SMPTE / EBU, ASCII (RS-232C & USB), ESE-TC89™ and ESE-TC90™. Six yellow LED displays (.56″) provide a digital display of the Hours, Minutes and Seconds data. Two (2) One Pulse Per Second outputs and a GPS “Lock” output are also standard features. 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 time data to be output. Several options are available that allow the unit to meet most any demand required of a Master Clock or Time Code Generator.

10nS10nS Accuracy: The accuracy of the unit is improved to 10nS.
AntGPS Antenna: High Performance GPS Antenna for harsh RF Environments.
BParallel BCD Output: CMOS compatible, 5-volt logic in parallel four-line format. Specify the ES-169B.
BBUBattery Back-Up: An internal Gel-Cell battery is provided capable of maintaining the unit's microprocessor for up to a 4-hour power outage.
ClearClear Anodized Front Panel
DCDC Operation: Requires the unit to be powered from a DC source exclusively, typically +12 to +35 VDC.
HRRelay Closure: Option "HR" provides a user programmable relay contact closure. The standard contact closure occurs on the Hour and Half Hour. If contact closures at other times are desired, the user can program up to four relay closures using the PC Software, which can be downloaded from the ESE web site. The reed relay is rated at 10 watts maximum resistive load (500 mA switching current) and is intended for control applications only. The relay contacts are accessible on the DB-9 connector.
