During such “free-wheeling” periods and while in operation, the network clocks shall provide a
visual indication that the device is relying on the internal oscillator and is not currently
synchronized to the network timeserver.
2.3.2 Analog clock engineering specification:
The shape of the analog clock shall be round 12” [30 cm] or 18” [46 cm]. The face of the clock shall
be off-white, the time indication marks on face shall be black. The hour markings shall be in an
Arabic numeral format and in an easily read font. Minute /second marking shall be provided. The
analog clock shall have black hour and minute hands and a red second hand indicator.
The analog clock shall contain a stepper motor drive and state of the art microprocessor and
electronics control to rapidly synchronize the hands on the face of the clock to an accurate NTP
(Network Time Protocol) reference.
The stepper motor drive and gear system shall be of all metal construction for long maintenance
free life and high product reliability. The gear and drive train system shall be smooth and quiet in
operation to minimize motor noise.
An LED status indicator on the face of the clock shall illuminate when the clock is not synchronized.
The analog clock shall be available with the following options: LED illumination, double face ceiling
or wall mount, stainless steel enclosure.
2.3.3 Digital clock engineering specification:
The displays shall utilize LED’s (Light Emitting Diodes) such that they are easy to read in various
lighting conditions, allow for large viewing angles, maximum-viewing distances, long life
expectance, and do not require back lighting. The LED’s shall be available in various colors
including red, amber, green, and blue displays for various visibility requirements and in various
sizes including 2.3” [5.8cm], 4” [10cm], and 8” [20cm] character heights. In addition, the brightness
of the LED display shall be fully adjustable via software to allow for the display to be dimmed or
brightened remotely, in order to accommodate various lighting conditions and requirements.
3.0 CONFIGURATION SOFTWARE
The network clock system shall be fully configurable and managed remotely through IP via software
to simplify the costs associated with administration.
GUI Interface – Windows configuration
The network clock system shall include a GUI (Graphical User Interface) based network software
application, operating under the Windows OS, for configuration and maintenance of [the network
time server and] all network clocks.
The GUI application shall include password protection of the clock configuration, encrypted
communication, and the ability to enable or disable options that might reduce security. A status
display to remotely monitor the time displayed on the clock, the internal UTC time, synchronization
status, and any error condition regarding the clocks network status shall be provided.
An optional advanced Windows based GUI configuration software package shall be available for
separate purchase, for quickly configuring groups of clocks with the ability to save and load
configurations.
Console interface – Unix/Linux, non-Windows platform configuration
A separate menu driven telnet console interface shall be provided for configuration, of the network
time server and network clocks on a non-Windows OS such as UNIX, Linux.
