1.0 INTRODUCTION
The 6500 is a multiple output, calendar programmable solid state master clock. It is used for synchronizing most
synchronous and electronic (carrier current) secondary clocks and for switching electric circuits according to a
preset time and date program. The 6500's AUTO PROMPTING, alphanumeric display makes programming fast
and simple. The outputs can be used to sound signals, to control audio/visual equipment or to control lighting,
heating, ventilating, air conditioning and security systems with a variety of programming capabilities, ranging
from a simple 7 day schedule to a more complex schedule utilizing its powerful, alternate annual programming
features.
Secondary clock correction modes are built-in, and can be selected from the keyboard. If a secondary clock
correction mode is selected, the 6500 will dedicate two of its relay outputs for correction, leaving six relay circuits
for control. If the 6500 is not being used for correcting secondary clocks (Mode 0), then all output relays are
available for timed events. Selected outputs can be independently programmed for momentary operation.

it will take the operator from setting time through setting the basic program entries.
Programmable Secondary Clock Modes - Simple keyboard entry allows for selection of the desired secondary
clock synchronization modes. Most secondary clock modes are included. Selecting Mode 0 disables secondary
clock correction, allowing all output relays to be used for timed events.
200 Powerful Program Entries - The 6500 has a default set up of 1 Basic 7 day program and 9 Alternate 7 day
programs that can be scheduled on an annual basis for a total of 10 programs, each having 20 program entries.
If more than 20-program events are needed, they can be programmed using a keyboard-entered function. Up to
100 events per program can be programmed for a total of 2 programs. Each event can be programmed for all or
any combination of the output relays for the specific day of the week, or for all 5 weekdays, or for both weekend
days, or for everyday of the week. In addition, the events can be programmed in customized groups such as,
Monday, Wednesday, and Friday only.
20 Annual programs - Each annual program has a starting and ending date, and an associated Alternate
programs. This feature can be used to schedule any 1 of the 1 to 9 alternate, 7 day program to be used by the
6500. Certain annual programs can be programmed to repeat on a yearly basis so that they don’t have to be
reprogrammed each year.
Programmable Daylight Savings Time Adjustment - The 6500 can be programmed to automatically adjust its
time for Daylight Savings Time changes, or other seasonal changes for all locations world-wide.
Automatic Leap Year Compensation.
Manual Override - The output relays can be manually energized or de-energized from the keyboard. The word

Time Code terminals provide user specified time code outputs for Secondary Clock Wiring. See the Wiring
Diagrams at the back of this manual for more detail.
4.0 GETTING STARTED
4.1 THE AUTO PROMPT DISPLAY
9

The master clock has a feature called Auto Prompt that guides the operator when programming the unit. For the
most part the operator merely has to follow the display as the master clock advances through the Program
Modes. On a restart (from a “power fail” condition) the master clock will advance through a sequence of all the
necessary settings including the Basic Programs. You may exit this sequence if desired and enter the program
manually from the time display, using the specific commands. Entering a program from the Auto Prompt
sequence is identical to entering one manually.
To exit the Auto Prompt sequence, simply press [EXIT] at any time. Then proceed to section 5.00 to continue
programming manually from the time display.
4.2 THE CURSOR, ENTERING DATA
On many of the display messages you will see a flashing square character called the cursor. The cursor
indicates that you may now enter or change the data at that position of the display. As data is entered the
master clock constantly checks for a valid entry. For example, you cannot enter 13 for a month when setting the
date. After entering valid data to a position on the display, the cursor will advance to the next position. If you
have tried to enter invalid data, the cursor will remain at the same position, indicating you must re-enter the data.
Simply re-enter the data on top of the existing data and press [ENTER]. Generally, data is entered two digits at
a time and shifts left with each entry.
4.3 APPLYING POWER, ENTERING THE TIME
Before power is applied, be sure all installation and wiring is completed to all local codes.
Upon first applying power the display will come up with a brief sign on message showing the model and version
numbers:
After a few seconds the first Auto Prompt message will appear. If the following message does not appear, read
Section 7.6 FORCING A RESTART.
Simply press key [3]. The display will prompt with the set time display.
It may be showing the correct time, some other time, or all “0’s”.
From this point forward you can exit the Auto Prompt sequence at any time, if desired, by pressing [EXIT].
However, the programming is simplified by staying in the Auto Prompt mode. (Note: To restart refer to Section
7.6 “Forcing a Restart” which will clear all information.) The cursor will be flashing in the hour’s digits. The
bottom line is a prompt to enter 2 digits (HH) for hours. Enter the hours then press the [ENTER] key. Two digits
are required for the hours. Example: 01 instead of 1. The cursor will remain flashing in the hour’s digits if an
invalid number is entered for the hours. Enter the correct hours. Once a valid number is entered for the hours,
the cursor will advance to the minute’s digits. Again, the bottom line is a prompt for entering the minutes. Type
10

two digits for the minutes and press [ENTER]. The cursor will advance to the AM position. Press the AM or
PM key then press [ENTER]. Time keeping begins the instant you press [ENTER]. Time can be accurately set
to the second by pressing the [ENTER] key at the desired instant.
4.4 ENTERING THE DATE
The next entry in the AUTO-PROMPT sequence is entering the date. The display will show:
It may be showing the correct date, some other date, or all “0’s”.
The cursor will be flashing in the month's position. The bottom line will give you additional information on how to
enter the data. Type the two digit number for the month and press [ENTER]. If the correct two digits are
already there, simply press [ENTER]. The cursor will move to the day position. Type the two digits for the day
and press [ENTER]. The cursor will move to the year position. Type the two digits for the year and press
[ENTER].
4.5 ENTERING THE DAY
Next, we enter the day of the week. The display will show:
It may be showing the correct day or some other day stored previously. Press the DAY key [4] until the desired
day is shown on the display and then press [ENTER].
4.6 DAYLIGHT SAVINGS TIME
The default entries for daylight savings time according to current U.S. law will display as follows:
The master clock is pre-loaded with the current daylight savings time settings according to U.S. law.
Unless the law changes or you live in an area that does not follow standard U.S. daylight savings time
there is no need to change anything on the DST screen. The top line is for the Start of DST and the bottom
line is for the End (Finish) of DST. The S indicates the Start of DST and the F indicates the Finish of DST. The
cursor will be flashing in the month position. Enter the two digits for the month in which you wish the Start DST
adjustment to be made (03 for current US law), then press [ENTER]. Enter 00 for the month if you do not wish to
use the automatic DST feature and the master clock will advance to the next Auto Prompt display. The cursor
will advance to the L in the Sunday position. Enter a 2 for the first Sunday (current US law), 2 for the second, 3
11

for the third, 4 for the fourth or L for the last Sunday. Use the [5] key to enter the L. The change will be made
at 02:00 AM on the Sunday you choose.
After the Start DST data is entered, the cursor will advance to the Finish DST line. If you have entered a Start
DST, you must enter a Finish DST as well. Failure to do so will erase the Start DST and then there will be no
DST compensation.
Finish DST is entered in the same manner as the Start DST. Current US law for Finish DST is the first Sunday in
November. Enter 11 for the month and 1 for the Sunday. The valid Sundays for the Finish DST are 1, 2, 3, 4
and L. Use the [5] key to enter the L. The change will be made at 02:00 AM on the Sunday you choose.
4.7 ENTERING PULSE (MOMENTARY OUTPUT) FOR RELAYS 1,3,4,5,6,7,8
(NOT RELAY 2)
The pulse is set to 5 seconds for Relays 1 and 2 by default, but can be set to 0 (OFF) if required. A pulsed
output may be needed for applications requiring a momentary output. If a relay is turned on without a PULSE
SETTING. The relay will stay on until programmed to turn off. This means signals, etc. will continue to
sound until programmed to turn off.
The cursor will be flashing on the "5" in OFF. If pulsed output is not wanted, press OFF [0], then [ENTER]. The
master clock will advance to the next Auto Prompt display. To program pulsed output on 1 or more output relays,
enter the duration for the pulse from 1 to 9 seconds and press [ENTER]. (If a mistake is made, to correct: exit
out, enter plan #, and step 0 will take you back.)
Enter the number of the relay or relays to pulse. Relay 2 will not be available for this pulse. Also, if you are
using any of the built-in correction modes, relays 3 and 4 will not be available for this pulse. The
examples above show all relays except relay 2 set to pulse for 3 seconds.
4.8 ENTERING THE PULSE FOR RELAY 2
Next the display will read:
The cursor will be flashing on the "5". If pulsed output is not wanted, press OFF [0], then [ENTER]. The master
clock will advance to the next Auto Prompt display. To program pulsed output on relay 2, enter the number of
seconds duration for this pulse from 1 to 9 seconds and press [ENTER].
4.9 ENTERING THE SECONDARY CLOCK MODE
12

Display will read:
If you are not correcting secondary clocks, you can set the mode to 0. In this mode all outputs are available for
timed events. Simply press [ENTER] to select mode 0, and the master clock will advance to the next Auto
Prompt display. To select a specific mode, press any key except [ENTER] or [EXIT]. This will advance the
display through the secondary clock modes. Once the desired secondary clock name and model number is
displayed, press [ENTER] to select that model. For the Simplex 59th minute correction, the display will be:
After pressing [ENTER] the master clock will advance to the next Auto Prompt display. Please note that relays 3
and 4 are dedicated to secondary clock correction and will no longer be available for timed events. A complete
list of clock correction modes supported by the Simplex 6500 will be found in the “Clock Modes Supported” table
