INTRODUCTION
GENERAL DESCRIPTION
TheDurantAmbassador5760X-402isacountcontroldevice
with three count registers - main counter, batch counter and
totalizer. The main counter has one preset and is typically
used to control cut length, fill quantity, or number of pieces/
container.Thebatchcountercountsthenumberoftimesthe
main counter has cycled and typically represents values
such as: pieces cut, containers filled, cartons made and etc.
The batch preset is useful for signaling or stopping the
process when the desired amount of product is completed.
The totalizer accumulates the total number of counts proc-
essed by the main counter. Its value represents the total
amount of material used by a process or the total number of
pieces processed.
PROGRAMMABLE I/O
One of the unique features of the Ambassador family of
counters is the programmability of the inputs and outputs.
Eachofthefourinputscanbeindependentlyprogrammedto
perform one of eight functions. The user can also select
which events (counter preset outputs, reset signals, output
control inputs, output timers, and serial commands) cause
eachof the threeoutputs (1 relayand 2 transistor)to pick-up
and drop-out. Any input(s) may be programmed for output
control, however, multiple output control inputs are paralled
into a single output control channel in the unit.
RATE METER
In addition to count/control capabilities, a rate meter is
provided to monitor the speed of the incoming count signal.
Thisratefeatureusesthe1/taumethod(eventtimemeasure-
ment)andcancalculateandscaletheratesothatevenalow
count speed (.1 Hz) can yield accurate rates in engineering
units(ft/sec,gal/min,etc).Theratefeatureoperatessimulta-
neously with the count/control functions.
DISPLAY
AllAmbassadorCount/Controlsareavailableingreenbacklit
LCD display and reverse image red LCD display versions.
MENU PROGRAMMING
AnotheruniquefeatureoftheAmbassadorfamilyofcounters
isthe menu driven programming. The two line alphanumeric
display prompts programming choices, thus eliminating the
need to remember or look up programming codes. A non-
volatile memory retains programming choices, presets, and
count values while power is removed.
APPLICATION
To better understand the features and capabilities of the
Ambassador, review the simplified block diagram at the top
of the next page and the programming diagrams on pages 6
through 9. Because of the Ambassadors’s versatility, both
programmingand wiring decisions must be made before the
counter can be operated. The following sequence of activi-
ties is recommended:
1. Answer the following questions:
What should each count register represent?
What should each output control or do?
What effect should each preset have on the outputs?
What should cause each count register to reset?
Which control signals should affect outputs (resets,
programmable inputs, output timers, etc)?
What engineering units should the rate represent?
2. Gothroughtheprogrammingsectionandmarkthechoices
required for the application.
3. Go through the wiring section and lay out the wiring
required. Remember that wiring is affected by program-
ming.
4. Wire and program the counter as determined in steps 2
and 3 above.

Receives the up or down signals and adds or subtracts the
scale factor value to/from the current scaler remainder. The
scaler outputs the integer result as up or down pulses. The

memory.
MAIN COUNTER
Counts the up and down pulses from the scaler. Every two
milliseconds,themaincounterchecksifitsvaluehaspassed
through the preset value (coincidence). For coincidence to
occur, the counter must count up to the preset in the reset to
zero mode and count down to zero in the reset to preset
mode.Ifcoincidencehasoccurred,themaincounteroutputs
a pulse on the main preset output. The main counter counts
intheoppositedirectionifitisprogrammedtoresettopreset.

Counts up when main counter reaches the main preset.
Everytwomilliseconds,thebatchcounter checks if its value

PROGRAMMABLE INPUTS
The Ambassador unit has five programmable inputs (RST/
CLR key and four terminals). The user may program each
input for one of eight functions (see INPUTS, page 10).

DESCRIPTION OF PROGRAM OPTIONS
SCALERS
C SCALER - the count scaler determines the value of each
input pulse. The counter displays whole numbers only. The
count scale factor affects the main counter and totalizer but
does not affect the rate meter. The count scaler’s decimal
point position is fixed.
C DEC PT - sets the decimal point position for the main
counter and totalizer. The decimal point position and scale
factor value are independent.
R SCALER - the rate scaler is used to adjust the rate meter
reading and compensate for the number of input pulses per
item. The rate scaler's decimal point is programmable. The
rate scaler and count scaler are independent.
R DEC PT - sets the decimal point position for the rate
display. The rate decimal point position and scale factor
value are independent.
COUNT INput
CONTACT ADD/SUB - input A adds counts and input B
subtracts counts. This mode includes input filtering to
debounce mechanical contacts.
CONTACTADD/ADD-inputsAandBbothaddcounts. This
mode includes input filtering to debounce mechanical con-

RESET TO ZERO - the main counter resets to zero when a
main counter reset occurs. The normal count direction is up
and the main counter outputs respond only when counting
up.
RESETTOP1()-themaincounterresetstothepresetvalue
when a main counter reset occurs. Preset coincidence oc-

CALCULATING SCALE FACTORS
COUNT SCALING
The count scaler is a user programmable number which
determines the count value of each input pulse. It is used to
correct for a known amount of error (wheel wear, viscosity,
etc.) or to convert the incoming count signal into the desired
units of measure on the display (feet, gallons, yards, etc.).
The main counter and totalizer show whole (integer) counts;
the scaler retains fractional counts.
Count Scaler Range: 0.00001 to 9.99999
Default Count Scaler: 1.00000
Count Scaler (CS) Formula:
DPF
CS =
PPI
where:
DPF is the decimal point factor determined by the desired
decimal point position on the main counter and totalizer
display:
DISPLAY DPF DISPLAY DPF

RATE SCALING
The 1/Tau rate meter calculates rate by measuring the time
interval between input pulses, converting to frequency, and
multiplying by the rate scaler. The rate scaler is user pro-
grammedto convert the count input pulse frequency into the
desiredunitsfordisplay(feet/minute,inches/second,boxes/
hour, etc.).
Rate Scaler Range: 0.00001 to 99999
Default Rate Scaler: 1.0000
Rate Scaler (RS) formula:
SEC x DPF
RS =
PPI
where:
SEC is the number of seconds in the rate time unit (items/
minute = 60, items/hour = 3600, etc.).
DPF is the decimal point factor determined by the desired
decimal point position on the rate meter display:
DISPLAY DPF DISPLAY DPF
XXXXXX = 1 XXX.XXX = 1,000
XXXXX.X = 10 XX.XXXX = 10,000
XXXX.XX = 100 X.XXXXX = 100,000
(Use the rate decimal point menu to select the desired
decimal point position for the rate meter.)
PPI is the number of pulses per item from the sensor (times
2 if doubled count mode).
Example 1: A sensor produces 1 pulse per foot of material
travel. Display rate in whole feet per minute (XXXXX).

power output. It is used to supply 12 VDC (+/- 25% 100 mA
max)foraccessories.DCCommonisthenegativesideofthis
supply.
On the model 57600 this terminal is used for the 10-15 VDC
powerinput.Connectthepositiveleadofthepowersupplyto
terminal 1 and the negative lead to DC Common.
The DC POWER OUTPUT contains a series Positive Tem-
perature Coefficient (PTC) resistor that undergoes a large
and abrupt increase in resistance when an over-current
condition occurs. This resistance change limits the fault
currenttoseveralmilliamps.ThePTCdevicewillresetwhen
theunit power has been removed for a time sufficient to cool
the device. The overload condition should be removed be-
fore unit power is reapplied.
2, 3 and 4 -DC Common: These terminals areconnected to
the negative side of the counter’s internal DC power supply.
Count inputs must be referenced to DC Common. Control
inputs are on when connected to DC Common. Transistor
outputs conduct to DC Common when picked up. For maxi-
mumnoiseimmunity,thegroundterminalmustbeconnected
to a good earth ground. All shielded signal cables should be
connected to earth ground or ground on the counter.
5, 6 and 7 - Not Used
8, 9 and 10 - Relay 1 contacts: The relay output consists of
oneelectricallyisolatedformCsetofcontacts.Theusermust
supply power through a contact to the external load. The
contacts remain in the normal state until a pick-up signal
occurs. The relay remains picked up (on) until a drop out
signaloccurs(seeoutput programmingdiagrampage8and
block diagram page 2).
11 and 12 - AC Power Inputs:
Model 57601-402 115VAC
Model 57602-402 230VAC
Model 57600-402 Not used
13, 14 - Transistor Outputs 2 and 1: These terminals are
separateopencollectorNPNtransistor outputs.Eachoutput
conducts to DC Common when picked up (see output pro-
gramming diagram page 8 and block diagram page 2).
15, 16, 17, and 18 - Inputs 1, 2, 3, and 4: Programmable
inputs. The user can assign one of eight functions to each
individual input. The inputs require a current sinking signal
(contact or solid state) to DC Common (see input program-
ming diagram page 7 and block diagram page 2).
19, 20 - Count Inputs B and A: Connect the count input
signal(s)totheseterminals.Thecount inputcanoperatewith
either a current sinking signal (contact or solid state) to DC
Common or a current sourcing signal. (See specifications,

MODULAR COMMUNICATION JACK
ThemodularphonejackisanalternateconnectiontotheRS-
485 communications port. Pin 2 is positive and is the same
asterminal 21. Pin 3 isnegative and is thesame as terminal
22. Pins 1 and 4 are connected to DC Common and should
be used for any shield connections.
Note: This jack is intended only for connection to Ambassa-
dor and other RS-485 communication networks. It
should not be connected to any telephone sys-
tem - damage or hazard may result.
TERMINAL BLOCKS
Connections to the Ambassador are made through deplug-
able, screw terminal blocks to allow for ease of wiring and
removal of the counter. The terminals can accommodate
stranded,solidorfusedwire(preferred)from14to22gauge.
To remove the terminal block, remove AC power and pry
gently underneath each end of the terminal block with small
screwdriver. Press straight on to re-install.
GENERAL WIRING PRACTICES
1. Disconnect all power before wiring terminals. A safety

The panel mounting kit includes:
(1) mounting gasket, (2) mounting clips and (4) screws.
Refer to the dimension diagram on page 28 for a drawing of
the correct installation of these parts.
The mounting gasket is coated on one side with a contact
adhesive and a paper backing. Care should be taken during
thegasketinstallationthatthegasketbecorrectlypositioned
onthepanelatthefirstattempt.Attemptingtore-position the
gasketoncetheadhesivehascomeincontactwiththepanel
is likely to deform or tear the gasket. This may result in an
improper seal. For best results, follow these directions:
1. Stand the Ambassador counter on a desk or table with
its display down, screw terminals up.
2. Remove and discard the center square of the gasket at
thescribemarksinthegasketandpaperbacking.Donot
remove the backing from the remaining outer rim.
3. Slide the gasket down the unit until it is in position at the
rear of the unit's front bezel. The paper backing side
should be up.
4. Insertthetipofaknifebetweenthepaperandthegasket
and, while holding the gasket down to the unit with the
knife, peel off the paper backing.
5. Slide the unit through the panel cutout until the gasket
firmly adheres to the panel.
6. Install the mounting clips and screws as shown in the
diagram 28. Do not overtighten the mounting screws.
Thescrewsshouldbetightenoughtofirmlyholdtheunit

Caution:
The unit requires 1.2 V P-to-P
minimum signal amplitude to
count. Magnetic pickups produce
an output voltage directly
proportional to the speed of the
ferrous material passing the
pickup. At low speeds, or at
starting or stopping, the output
voltage from the pickup may not
be great enough to cause the
counter to count. For magnetic
pickup signals in the range of 50
mV to 400 V P-to-P, a signal
conditioner (Durant part no.
48160-400) is recommended.

Theadvancedcommunication capability of theAmbassador
control allows a host computer to read and reset counters,
read and write presets, inhibit and enable counts, turn
outputs on and off, lock and unlock the keyboard, and read
and program all setup parameters.
The Control uses ASCII code with the RS-485 serial specifi-
cation and Opto-22 compatible protocol. This allows bi-
directional communications and addressing of multiple con-
trols on a single two-wire communication bus. Each unit is
individually addressed via a user programmable ID number.
Up to 100 counters can be connected directly to the bus.
Interconnect kits and bulk RS-485 communication cable are
available; see accessory parts list.
SERIAL COMMAND FORMAT
The general command format is shown below. Spaces are
used for clarity only and must not be transmitted.
> ID# COMMAND [numeric data] CHECKSUM (cr)
Example:
To cause unit# 10 to transmit the value of the main counter,
send the RCD command as follows:
1. Message start character (ASCII 62). Required for all
transmissions to the control.
2. Two digit serial port ID# in hexadecimal. Required for all
transmissions to the control. Unit ID# 10 (decimal) is unit
ID# 0A (hexadecimal). Capital letters must be used.
3. RCD (Read Counter Data) command. All serial com-
mandsconsistofthreecharacters. Lettersmay beupper
or lower case. (See pages 19 - 21 for description of all
commands.)

19
4. NumericdatarequiredwiththeRCDcommandtospecify
counteror presetto be read. Up to eight numeric charac-
ters are required for some commands. Most commands
do not require any numeric characters (see pages 19
through 21 for list of all commands).
5. Two digit hexadecimal checksum of the ASCII values of
the ID number, command, and any required numeric
characters. Required for all transmissions to the control.
Checksum Calculation:
The checksum is the last two hexadecimal characters —
7A. Upperor lower case letters may be used.The > start
characterand carriage returnare not used in calculation.
6. ASCII carriage return (13 decimal). Required at the end
of all commands.
SERIAL RESPONSE FORMAT
The counter does not respond to a command unless the
transmitted ID number matches its programmed ID number.
If the ID numbers match and the command and checksum
arevalid,thecontrolexecutesthecommandandtransmitsa
response as shown below:
A [data] [checksum] (cr) where:
A is the acknowledge character (ASCII 65) sent when any
valid command is received and executed.
[data] is sent in response to the RCD, RDV, or RPI com-
mands which request data. Data is not transmitted for
other commands.
[checksum] issent onlywhen data is requested (RCD, RDV
or RPI commands). The checksum is calculated by add-
ing the ASCII values of all preceding characters (includ-
ing spaces), but excluding the acknowledge character
"A". Thechecksumisthetwoleastsignificantdigitsofthis
sum in hexadecimal.
(cr) is the ASCII carriage return (13 decimal). Transmitted at
the end of all responses.
EXAMPLES:
A(cr) No data requested
ACT 337914 52(cr) Count data requested
If the ID numbers match but the command is not valid or
cannot be executed, the counter ignores the command and
SERIAL COMMAND/RESPONSE FORMAT
responds by sending an ASCII “N” (not acknowledged)
followedbyaone charactererrorcodeandacarriagereturn.
Error Codes:
00 - PowerupError—Whenpowerisappliedtotheunit,or
the program mode is exited, the unit performs a power
up self test. The first valid command received by the
unit following the self test is not executed and not
acknowledged.
10 - Lock input is on — cannot change preset values or
enter serial program mode until lock input is removed.
02 - Checksumerror—receivedchecksumdoesnotmatch
calculated checksum.
01 - Command not found in table or invalid command —
WPI, RPI, XSP received when not in serial program
mode.
05 - Invalid data — incorrect number of digits or illegal
character received in data field.
11 - Preset edit in progress on keyboard — serial preset
cannot be sent if preset is being changed on the
keyboard.
12 - Command is valid for this family but not this counter or
commandisnotvalidwiththisprogramconfiguration—
cannot change output time if output is set to latch.
13 - Keyboardprogrammingmodeisactive—cannotenter
serial program mode if in keyboard program mode.
