Description
The Multifunction Timer/Counter Model 54035A is designed to time and count events with high accuracy
and high resolution. It features millisecond timing up to 1000 seconds and counting up to 1000 counts. It can
take the place of Lafayette’s Stop Clock Model 54030 and Clock/Counter Model 54035 while improving on the
functions of both. It can be set to acquire time and counts simultaneously on three separate channels or can
record up to four split times on a single channel. Time and count data are displayed on a high-contrast back-
lit display. Data can also be transferred to a computer via a standard serial port interface. The Multifunction
Timer/Counter Model 54035A provides a row of (12) terminal blocks for easy connection to external devices. An
optional banana plug interface is also available for connection using standard banana plugs. All timing functions
are activated by external switch closures with built in capability to interface to normally open or normally
closed switches. Timing functions are also available via front panel controls so that any function previously
performed with a Lafayette’s Stop Clock Model 54030 or Clock/Counter Model 54035 can be duplicated by the
new Multifunction Timer/Counter Model 54035A.

Denition of Terms
For the purposes of understanding procedures and explanations in the manual it is important to recognize
the dierences in the following terms:
Timing: The timer is accumulating time in milliseconds after the start button is pressed.Timing will continue
until a stop button is pressed.
Running: The timer is accumulating the total time in milliseconds that a button or external event is activated.
Running will continue until the button or external event is released.
Counting: The timer is accumulating the total number of times a button or external event is activated.The timer
will simultaneously accumulate running and counting of buttons or external events.
Timer Modes
The Multifunction Timer/Counter Model 54035A uses two separate timer modes. One is a single timer mode
and the other is a multiple timer mode.The mode is selectable by pressing the mode button on the front panel
or via instructions on the serial communication port (see Communications directions, pg. 9, for details). In order
to enter the mode menu, the timer must be reset.
Single Mode
The single timer mode consists of a single master timer that can be programmed for up to four split times. The
stop number (1-4) is reported on the display when a stop is pressed. Once the start button is pressed, each
stop button can only be pressed once until all split times have been recorded. After the nal stop, the start
button can be pressed again, but the nal split time will be overwritten by the new time. After a restart, any
stop button can be used to stop the timer and the stop number will be updated as the new time is recorded.
Multiple Mode
The multiple timer mode consists of a single master timer and two independent run/count inputs that can
time and count external events simultaneously. In multiple timer mode, the stop1 and stop2 inputs on the
back panel become the run1 and run2 inputs. The stop1 input on the front panel becomes the scroll control
button. The scroll is only active in multiple timer mode. The start button can be used in multiple timer mode
to start the master timer only. Any available stop button can be used to stop the master timer, but there is no
stop identication number displayed in multiple timer mode. Run1 and Run2 inputs can not be activated with
the start button, they are strictly run/count inputs.

Front Panel Controls
1. Power switch: Turns on the timer. When in the on position, the display backlight will come on and the
company, model identication, and version number will appear on the display for four seconds.
2. Start: Starts timing in both single and multiple timer mode. Can also be used to restart the timer after the
last split time has ended in single timer mode.
3. Stop 1-4: Stops timing in all modes. In single timer mode, the stop button pushed will be identied on
the display. If split times are being used, a stop button can only be pressed once per time cycle. This is to
prevent loss of split time data. Once the nal split time is recorded (master time stopped), then the start
button can be used to restart the timer and any stop can be used any number of times. The split times will
remain on the screen with only the nal time being updated.
4. Scroll: Active in multiple timer mode only. It will shift the display from showing the master time and run/
count1 to showing run/count2. Also note that since scroll is enabled, the stop1 button on the front panel
can not be used to stop the master timer in multiple timer mode.
5. Mode: Sets up the timer for single timer operation or multiple timer operation.To prevent accidental loss
of data, the timer must be reset before the mode menu can be entered. If single timer operation is selected,
the timer will give a prompt for the desired number of split times. This prompt will be skipped if multiple
timer operation is selected because split timing is not available in multiple timer mode.The timer will also
congure the back panel inputs to sense normally open (NO) or normally closed (NC) switches. The menu
will step through all seven inputs, but can be ended at any time by selecting end from the menu. All back
panel inputs default to normally open when the timer is turned on. However, the inputs are not reset to
default when changing modes. Also note that when in multiple timer mode, the settings for stop1 and
stop2, become run1 and run2.
6. Reset: Clears all time registers to zero and sets display to its initial state.To prevent accidental loss of data,
the master timer must be stopped before a reset can occur. If the timer is timing, the reset button will
function as stop3.
7. Run/Cnt: Activates running for as long as the button is held down. Also increments counter by one for each
time the button is pushed.This button can be used in either mode to run the master timer and accumulate
counts. If the master timer is timing (start button pushed) then the run/count on the front panel will function
as stop4. After a stop button is pushed, the timer can not run or count until reset is pressed. However, the
timer can be started at any time even if run times or counts have been accumulated.

Back Panel Controls
Back panel functions are activated by opening or closing external switches. All inputs are independently
programmable from the mode menu to sense a normally open (NO) or normally closed (NC) switch. In all cases,
one side of the switch is tied to the appropriate input and the other side is tied to one of the four ground inputs.
Any switch can use any of the ground inputs and any ground input can be tied to more than one switch. Do
not apply voltage to any input. Doing so may damage the equipment and void the warranty.
1. Start: Starts timing in both modes.The two start inputs provided are tied together so that multiple timers
can be linked together with a common start signal.
2. Stop1/Run1: In single timer mode, this input is for stop1, in multiple timer mode, it is for run/count1. This
external input is the only way to activate run1/count1.
3. Stop2/Run2: In single timer mode, this input is for stop2, in multiple timer mode, it is for run/count2. This
external input is the only way to activate run/count2.
4. Stop3: Stops the timer in any mode. Designated as Stop3 when in single timer mode and as a generic stop
when in multiple timer mode.
5. Stop4: Stops the timer in any mode. Designated as Stop4 when in single timer mode and as a generic stop
when in multiple timer mode.
6. Reset: Clears all time registers to zero and resets the display to its initial state. To prevent accidental loss
of data, the master timer must be stopped before a reset can occur.
7. Run/Cnt: Will simultaneously track how long an external button (or input) is held down and how many
times the button has been pressed. This input can also be used to count events while the timer is timing.
Note that in single timer mode, the counter can not be used if more than two split times are selected. Also
note that no counts can be accumulated after the timer has stopped. In multiple mode, this input controls
the main timer and counter.

Other Features
1. Battery Saver: If batteries are being used to power the 54035A, the battery saver mode will be enabled.
The battery saver mode will turn o the LCD backlight if there is no activity on the timer for 30 seconds.
Any button press or external input activity will turn the light back on. The front panel buttons will turn the
light on without performing the actual function of the button.The external inputs or serial commands will
perform the designated function in addition to turning on the backlight. Plugging in the DC power supply
will automatically disable the battery saver feature.
2. Low Battery Detect: If the 54035A is operated on the batteries for an extended period on time, they will
eventually become too weak to provide the necessary power to the timer. When this happens, the timer
will turn o the backlight to reserve the remaining power. It will also display the message “low batt” on
the display (this message is not displayed in multiple timer mode, so check the status in single timer mode
if the light goes o and battery saver mode is not active). The timer will function normally in “low batt”
mode until the batteries are completely dead. The only problem with operation on low batteries is that
the display contrast will become poor (see the section on changing the contrast to improve this situation).
The timer will continue to function for several hours with low batteries, giving ample time to nish timing
tasks or testing procedures and change the batteries.
3. Computer Interface: The 54035A can connect to a computer’s serial port via a standard nine pin cable.This
allows computer control of the timer and allows the computer to upload time and count data for display
and storage. Refer to the section on Communications for serial protocols and command codes.
Special Operations
1. Changing the Batteries: Access to the batteries is provided on the bottom of the 54035A. Using a
screwdriver or coin, turn each of the thumbscrews and remove the battery cover plate. The batteries are
provided with two ribbon loops to aid in removal. When inserting the batteries, place each pair of side by
side batteries through a loop and insert. Each ribbon should then be under a pair of batteries. Failure to
use the ribbon may result in diculty in removing the batteries (ie. they will have to be pried out). Also
note each battery polarity as imprinted on each battery holder. Replace cover after batteries are in place
and turn the thumbscrews down to secure the cover.
2. Selecting NO/NC switch type: When in the mode menu, the timer will prompt the user to congure each
input on the back panel as Normally Open (NO) or Normally Closed (NC). Normally open can be thought
as a “Press to Activate” setting and normally closed can be thought as a “Release to Activate” setting. A
majority of all applications and switches will be normally open. This is the default setting on all external
inputs. Unless it is known for sure that an application calls for a normally closed switch, the settings will
probably not need to be reset. If a switch is set up wrong, unexpected results may occur. If more than one
switch is set up wrong, the timer may go into a state where it times at random and the controls become
ineective. In this case, the only solution is to turn the timer o and redo the setup.
3. Contrast Adjust: As the batteries on the 54035A become weak, the numbers on the display will become
noticeably dim. This will occur to some degree even before the low battery message is displayed. If this
condition becomes a problem, the user can adjust the contrast on the display. The contrast is adjusted by
removing the battery door and turning the small white dial located just above the batteries with a small
screwdriver. The dial will only need to be turned a very small amount in the counterclockwise direction.
Note that when fresh batteries are inserted or the DC power is plugged in, the display will have too much
contrast (the background will turn dark) and will have to be adjusted in the clockwise direction.

Optional Accessories
The 54035A currently has two accessory items that may be useful in some applications
Banana Plug Interface: Provides a way to connect standard banana plugs to the external input terminal blocks.
Timer Control Software: Provides a software program to control the timing and counting functions of the timer
via the computer. Also provides data storage capability so that timing data can be stored in a le and analyzed
at a later date.
Contact Lafayette Instrument about pricing and availability of these products.
Communications
The 54035A provides a communications port so that it can be connected through a computer via a standard
serial port. The main purpose of this function is to provide a way to get the data collected by the timer into the
computer for storage and analysis. An eort was made to keep the communication protocol and commands
simple enough so that the user could easily write their own timer control application. In the event that resources
are unavailable for writing applications, a ready made software program is available from Lafayette Instrument.
The serial port on the computer should be set as shown below:
Serial communication protocol: 4800 baud, no parity, 8 bit ASCII, 1 stop bit or (4800,N,8,1).
The 54035A sends and receives only ASCII characters. Each control is activated by sending a single ASCII
character ( the timer is case sensitive):
ASCII Function
S - Start
1 - Stop1
2 - Stop2
3 - Stop3
4 - Stop4
C - Begin run/count
E - End run/count
M - Mode
R - Reset
D - Upload data
When the “Upload Data” command is issued, the timer will respond by sending all time and count data (even
if it is zero). The data is sent as seven ASCII bytes per data value in this order: Count1, Time1, Time2, Time3,
Time4, Count2, Count3. The serial buer, therefore, should be set up to receive 49 bytes with the length set to
7. Once the data is received, it can be broken up into its seven character data sets.
If the mode menu is accessed via the serial port, the computer will need to send, in succession, the same
ASCII value as the number requested on the timer display (if the choice is “1-single 2-multiple” send a “1” or a
“2” and so on).
The data sent to computer is the same as displayed on the timer. For example, if stop1 is pressed on the front
panel, that data will be placed in time1 on the serial communication. In multiple timer mode, the master time
data will be placed in time1 no matter which stop is pressed. Likewise, the count data will be placed in count1,
the data for run1 will be placed in time2 and count 2, and the data for run2 will be placed in time3 and count3.
There will be no count2 or count3 data available in single timer mode. Also, run1 and run2 are not accessible
through the computer, only through the back panel. However, the data for these inputs can be uploaded to
the computer.

Timer Control Software Model 54035A-SF
The Multi-Function Timer/Counter is available with software that can be used to control the timer and collect
and store data. The software interfaces to the timer via a standard serial connection. The software is built to
send and receive data from the timer; no timing functions can be performed by the software itself. The software
features a display that will show all time and count data gathered by the 54035A. It also has control buttons
that mirror the buttons on the timer itself. In general, the software is designed to function exactly as the front
panel control of the 54035A with the exception of it’s data storage capabilities.
Installation
** Windows 95 or higher is required to run the 54035A software.
1. Insert Installation disk 1 into the A: oppy disk drive.
2. Go to “Start”>>Run and type A:\setup.exe
3. Insert disk 2 into the A: disk drive when prompted.
4. Select a destination directory and click the computer icon to proceed with the installation.
5. Insert disk 3 into the A: disk drive when prompted.
6. To start the program, run 54035a.exe.
Software Functions
Comm port selection
On startup, the software will ask the user to designate which comm port to use with the 54035A. The selection
will default to comm 2 as most computers use a mouse on comm 1. Selecting the comm port in use by the
mouse will result in an error and/or disabling of the mouse. If the mouse is disabled, the computer will have
to be restarted to restore function.
Timing functions
1. Start: Starts the timer.
2. Stop1: Stops the timer, records split time 1 and updates the screen.
3. Stop2: Stops the timer, records split time 2 and updates the screen.
4. Stop3: Stops the timer, records split time 3 and updates the screen.
5. Stop4: Stops the timer, records split time 4 and updates the screen.
6. Reset: Clears the display, and sets all time and count data to zero. Reset can not be executed while the
timer is timing.
7. Mode: Enters the Mode menu on the timer and in the software. If the mode menu in entered from the
software, all settings should be set changed from the software. If settings are entered manually on the
timer while the mode menu is active on the software, errors in the settings may occur. The mode menu
can not be entered unless the timer has been reset.
8. Update Data: Transfers all time and count data from the 54035A to the computer screen. This is used when
the times are collected with the timer controls and the software is only used to display or store the data.
9. Select File: Allows the user to designate a le to store data gathered from the 54035A. All les are opened
as“Append”, so les may be opened multiple times without data being overwritten. Data from new trials is
added to the preexisting data. After the le is selected, the user will be prompted to enter a subject name
or trial description. This entry will be used to identify results in the storage le.

Model 54035A User’s Manual
Fax: [phone] . www.lafayetteinstrument.com . inf[email protected]om 9
10. Change Subject: This button allows the user to perform multiple tests in the same storage le. The test
data for each new subject is kept in a separate table inside the same storage le. The subject entry is used
to identify each data table. This feature is useful for running multiple subjects on the same test.
11. Save Data: This button stores the time and count data on the screen into the le designated by the user.
The user must designate a le and subject before data can be stored.
12. Auto Store Data: This selection will automatically store the present time and count data anytime the
following buttons are pressed: Stop1, Stop2, Stop3, Stop4, Reset, and Update data.To activate this function,
click the check box under the “Save Data” button. When the box is checked, the auto store function is in
eect. Upon checking the box, the software will prompt the user to designate a storage le and subject
name.
Notes
• If the timer is set to Multiple timer mode, all four stops will record on split time 1.
• If the computer is used to start and stop events, there will be a slight delay ( a few milliseconds) between
the pressing of the button, and the execution of the event on the LCD screen of the 54035A. This delay may
or may not be noticeable to the user. It is due to the serial communication timing and can not be improved.
For the most accurate timing results, start and stop the timer from the front or back panel on the 54035A
and use the computer to upload the time data.
Results File Format
All time and count data is stored in an ASCII format. Any program capable of reading this format can be used
to view the data (Excel, Notepad, Word etc.). Please note that if the 54035A software has opened a le, it may
not be possible to view the le until the 54035A software is exited. Each set of data in the le has a header that
includes the subject name and the time and date the le was created. Each time a“Save data”command or auto
store command is given, a line is entered in the results table showing the time and count data present on the
54035A at the time of the command. An event column shows which command in the software triggered each
line of data to be stored. A separate table is given for each dierent subject inside the storage le.
Applications
Directions in this section (next seven pages) detail setup procedures for interfacing the Multifunction Timer/
Counter to specic Lafayette Instrument equipment. If the equipment being used does not appear on this list,
contact Lafayette Instrument for application instructions.
Setting the Timer to Multiple time mode
Many applications in this section require the timer to be set up in “multiple” timer mode. To do this setup,
simply press the mode button and select “2-multiple”by pressing“2”. Make sure that the timer is stopped and
reset before attempting to enter the mode menu. The mode menu will then prompt to set the switch types.
Unless the application calls for normally closed switches, exit this portion of the menu by pressing“3”for “end”.

Split Timing with Infrared Switches Model 63501IR
The 54035A Multifunction Timer/Counter can be used in many applications where split timing is required
(i.e. track and eld events). To set the 54035A for split timing, press the MODE button and select “1-single”.
The menu will ask for the desired number of split times (up to four). The menu will then ask to select either
normally open (NO) or normally closed (NC) switch types. Since the infrared switches will be used, all switch
types should be set to NO (this is the default setting for the switch types, so press“3-end” to skip the setup if
no changes have been made).
To set up the switches
1. Set the 54035A to “single” mode with the desired number of split times.
2. Connect the red binding post of each switch to a stop input on the rear of the 54035A.
3. Connect the black binding post of each switch to the one of the four GND inputs on the rear of the 54035A.
To start an event, a remote pushbutton can be connected to the START input on the rear of the 54035A, or a
trial can begin by pressing the START button on the front panel. The infrared switches should be positioned
as desired to record events. The 54035A will automatically show the order in which the switches are triggered.
Figure 5: 63501IR/54035A Connection Diagram
Using the Timer for Over Four Split Times
If more than four split times are desired, a second 54035A can be added to the setup. Use the second START
input on the rst timer to connect to a START input on the second timer. Also be sure to connect one GND
input from the rst timer to a GND input on the second timer. Setup the second timer as the rst with switches
connected to the appropriate STOP and GND inputs. A single start button can then start both timers with each
stop showing total elapsed time from the initial start. Any number of clocks can be added in this way as long
as there is a common start signal and a common GND connection between all of the dierent clocks.

post should be connected to any of the GND inputs. When connected, the 54035A will show the time on target
over the length of a trial. Since the 54035A also counts the switch closure, it will also show total number of times
on target. Note that there will be a slight variance between the 54035A and the built-in 30010A timer due to the
dierent resolutions of the timers. The 54035A can be set to either single or multiple timer mode for this test.
Steadiness Testers, Groove and Hole Types Models 32010, 32011
Both types of steadiness testers can connect to the 54035A via the RUN/CNT input. Each tester has a binding
post on the apparatus. This binding post should be connected to any GND input on the 54035A. The stylus for
the device should be connected to the RUN/CNT input on the 54035A. The 54035A will show both the number
of errors and the total time for the errors. The time value will help the tester know if a subject intentionally
produces a continuous error in order to reduce the total number of counts. The 54035A can be set to either
single or multiple timer mode for these tests.
Tapping Board Model 32012
The 54035A connects to the 32012 via the RUN/CNT input.The binding post on the board connects to any GND
input on the 54035A. The stylus for the tapping board connects to the RUN/CNT input. The 54035A will show
the number of counts or taps along with the contact time for each tap. The time reading for this experiment
can be disregarded. The 54035A can be set to either single or multiple timer mode for this test.
Mirror Tracer/Two Arm Coordination tests Models 58024A, 32532
The 54035A can be used with both of these tests to time and count responses. The 58024A comes with its own
counter, but the 54035A can be substituted if desired. To set up, connect the black binding post on the device
to any GND input on the 54035A. Connect the red binding post to the RUN/CNT input. The 54035A will show
total number of errors and the total time o target. The 54035A can be set to either single or multiple timer
mode for these tests.
Visual Choice Reaction Timer Model 63035
The 54035A can be used with the 63035 to record response time. To set up, connect the black binding post on
the side of the 63035 to any GND input on the rear of 54035A. Connect the red binding post to the RUN/CNT
input on the 54035A. The 54035A will show the total time between the stimulus and response. The 54035A
will also show counts, but they can be ignored. The 54035A can be set to either single or multiple timer mode
for this test.
Linear Movement Apparatus Model 31202
The 54035A can be used with the Linear Movement Apparatus to show total movement time.To setup, program
the timer for single timer mode with one split time (this is the default mode when the timer is turned on).
Connect both black terminals to any GND input on the 54035A. Connect the green terminal to the START input
and the red terminal to the STOP1 input.
