'CNS Clock' Sync Your PC to GPS Atomic Clock 1PPS/RS-232 Outputs
Usually $789 Includes Tac32 Software (Full Version)
CNS Clock Features (Full details may be found here)
* Two external low impedance, fast rise time 1PPS signals for "laboratory" applications.
* Two external RS232 level 1PPS signals for computer applications.
* A high efficiency switching power supply that operates from any 9-30 volt DC source (100-240V AC Input).
* Optional Paging Sequencer Module for synchronizing paging base stations with overlapping coverage.
* Optional Serial Protocol Module custom applications using the serial port such as the Genysis module for the railroad industry.
* Battery Backup so the GPS receiver can wake up "smart."
* Provides 5 volt dc power for an amplified GPS antenna.
* Tac32 software [included] with a wide range of timing features as well as self-survey, logging, 1PPS steering, and PC clock synchronization.
* Optional Tac32Plus software [not included] for advanced applications.
* EMI certified to FCC Part 15, Subpart B and CISPR 22:1994 (both radiated and conducted emissions).
* Accuracy: In position hold mode, <20 nsec 1-sigma with SA off.
* The core of the CNS Clock is a GPS receiver module. The standard version of the CNS Clock features the best available GPS receiver, the Motorola M12+ Timing module.
* Each of the external 1 PPS output signals are independently buffered to improve their drive capabilities and to prevent damage to the GPS receiver module. The buffers will drive +3 volts into a 50 ohm termination with a rise time of <10 nsec. The normal logic polarity is positive going at the epoch time, but this can be inverted if desired.
* An RS232 driver provides 1 PPS time synchronization to an attached computer. The 1 PPS signal is normally connected to the computer's DCD input but connection to CTS or DSR is supported.
* The RS232 I/O ports are buffered and isolated from the GPS receiver module.
* Two RS232 ports are provided, a primary and a secondary. This allows, for example, control and monitoring using Tac32 software on one port while the other port is used fo a second computer, running NTP software.
* TNC Female Antenna Connector.
* Two BNC Female buffered 1 pulse-per-second (1PPS) outputs.
* Power connector, 2.1x5.5 mm coaxial, 9-30 volts @ 250ma (nominal).
* Fuse: 1/5 amp, 250 volt, fast acting, 5x20 mm.
