OPTIONAL MASTER CLOCK
As NASD firms come in
all sizes, so we too have developed various sized and featured
systems to meet the needs of the market. Our basic master clock
model MCC-B3 consists of the following features: It is
microprocessor based with modem capabilities, RS485 output
for time stamps, a two line LCD display of the time, date and
messages, a key pad for program selection and our software for
automatic dial out to the atomic clock upon power up,
synchronization and download of the time to the time stamps and a
timing board which hold accuracy to 2 seconds per day. This is all
packaged in a box 12" inches long, by 7" high by 6" deep. If
necessary this box can also hold 1 Repeater Board. We also offer as
optional extras Diagnostic software (Model MCC-B2) that highlights
on your scrolling display any time stamps no longer receiving their
time corrections. Another option is a full size (14") video display
and keyboard (Model MCC-B3) for a simultaneous viewing of the time
stamps on the system and their status. The RS485 of this master can
handle up to 30 time stamps on a daisy chain wiring configuration.
However we have found that many customers wire in a home run fashion
and others need machines in remote private offices and may require a
combination of both daisy chain and home run on the same system.
This can be accomplished by the use of repeater boxes. Usually in
systems of about 10 machines and more a repeater box is recommended.
For larger systems we
have developed the master clock computer system model MCC-A. This
model is a modified 386 or better computer that is dedicated to this
system and features an extremely accurate timing board with 1/3 rd
of a second per day accuracy. It also includes a 14" color monitor
to view the diagnostic program, full size keyboard, RS 485
interface, modem, DOS operating system, PC Anywhere (to help with
customer service), and our special software pack with dial out and
synchronization program time stamp translation and diagnostic
monitoring.
The monitor is a color
monitor as our diagnostic program uses colors to identify clocks
that have not responded to time change signals. With PC Anywhere we
can remotely phone into the computer and run the diagnostic program
to assist you if you are experiencing any system problems. This
master used in combination with multiple repeaters can handle
systems as small as a couple of time stamps to hundreds.
It is highly
recommended that the master be on an UPS power system. The master
will require a standard phone line and jack (RJ11) for the
communication with the atomic clock. This can be a shared line as
the computer will only be calling a couple of times a day.
REPEATER BOXES
Repeater boxes are used
to boost the power of the signal to the various circuits of stamps.
It consists of a metal box containing one or two circuit boards with
eight (8) circuits per board and RS485 connectors. Depending on your
wiring configuration one box can handle 16 time stamps in a "home
run" situation or in a "daisy chain" of 8 circuits it can control
240 to 480 time stamps.
The boxes are about
12" long by 7" high by 6" deep and can hold up to two repeater
boards per box. They require 110V 60 Hz electrical circuit. All
wiring to the computer and time stamp uses RJ45 jacks. These boards
have several lights that denote various operations are taking place
such as downloads from the master, time out to stamps, power
situations and problems can be highlighted by the lighting
sequences.
WTV TIME STAMPS
The WTV OATS compliant
time stamp is a modified version of one of the worlds most popular
and reliable electronic time stamps. Since OATS requirements are for
time in seconds, the only technology currently available is the
electronic time stamp with dot matrix printing. Each impression
takes about 400 milliseconds.
The display indicates
the date (01-31), day (m-s), standard am/pm hours (1-12), minutes
(00-59), machine number and accuracy status. The imprint
consists of the year (2005), month (00-12), date (01-31), military
hour's (00-23), minutes (00-59) and seconds (00-59) (see
sample imprint above). Regulations require the numeric month and
military hours. One unique feature of the WTV is its two-way
communication capability; it can report its synchronization status
back to the computer's monitoring program.
For security purposes
no clock has the ability to be reset on it's own; it must be
connected to the computer and will receive a reset signal within one
minute. For security purposes if a clock does not receive a down
load for a ten minute period it will automatically flash a non sync
message on it's display, the computer monitor will display that
clock's number in red and the timing chip in the individual clock
will allow it to work for up to 8 hours then will automatically shut
it down. The imprint will display a message designating the time as
no sync. Each machine has a specific number needed for communication
purposes; this number is technician changeable if a machine has to
be substituted.
