PIF File for Running PSL Explorer Under Windows 3.1 and
Labs Originally a product of the IBM
EduQuest Division, PSL was developed by T.E.R.C. and IBM in
the late 1980s and was available in 1989. Team Labs was
formed in 1994 when the PSL design team spun off from IBM.
Team Lab's 1997 Catalog
Not much is available on the web. Team Labs looks to have
switched their focus over to a Thinkpad based system @ 2000,
and the Explorer and Excelerator products aren't listed...
If you have documentation or actual experience with the PSL,
we would like to hear it.
PSL Explorer Versions
Save files on a non-ICLASS network.
School Vista Version 2.0 Ready.
A Windows and Windows 95 setup procedure
was added, allowing either the creation of a Personal
Science Laboratory Program Group with a PSL Explorer icon,
or the addition of the PSL Explorer icon to an existing PSL
School Vista Version 2.0 ready
RMP, DMM and PEP communications improved.
pH calibration process improved.
Default RMP range has been changed to +/-
Help messages for PSL Driver problems and
multiple probe calibrations improved.
Print function has been improved:
- Default print orientation is Landscape and
better scale factors for inkjet and laser printers
- Increased screen contrast to improve screen
User messages modified to improve clarity
Network print opns corrected under ICLASS
and non-ICLASS network installations.
Directory/disk interface problems on
ICLASS networks were corrected.
F6-CHDrive for non-ICLASS networks
resembles stand-alone operation, rather than ICLASS. This
was modified for ICLASS networks to match Explorer Version
1.01 Extended functionality.
Installation/setup process configures
Host PC to use DEVICE.COM to install PSL Device Driver
(PSLDEV1.SYS) in memory, rather than loading it through
CONFIG.SYS. This saves RAM on the Host PC and simplifies
network installations, since the Boot Image passed down from
the server no longer needs to have the device driver load
statement in it.
ICLASS (IBM Classroom LAN Administration
System Services) assumes certain rules about directory
navigation and file access. These rules are applied only
when PSL Explorer senses that an attached LAN is managed by
ICLASS. That means that PSL now runs on a straight Novell
Network! Non-ICLASS networks are simply treated as remote
Experiment setup files are now organized
into subdirectories. Fusion Series uses this organization,
and allowing navigation up and down through the file
structure helps you organize other PSL Setup files as well.
Natural (Napierian) logarithms and
exponentials are included in calculation options.
Force Probe support (attaches through DMM
Supports any probe or device that
produces a proportional voltage. Attach device to DMM,
supply a slope and offset to convert the measurement of
voltage to other units of your choice. The relationship must
be linear for full accuracy.
An uninstall procedure has been added to
the PSL Explorer diskette.
Distance, Light, Rotary Motion Probes,
DMM, can now sample at <1 sample per sec.
Pulse Timer and Event Timer options
support non-PSL photogates and switching devices.
Checks PSL DOS Driver to ensure it is at
the correct release level.
Records timestamps more precisely, which
eliminates "jitter" in derivatives.
Eliminates hangs and "No PSL Found"
conditions with RMP, PEP, and DMM.
Print portions of Table data, rather than
Delete range of points from graph by
"Marking" > "Change," > "Delete Marked Points."
DMM and RMP can be used with Keyboard
Sample rate can be specified for any
experiment; i.e., all types of probes.
RMP triggering enhanced to six different
Communications problems reduced w/
improved internal reset and recovery procedures.
DMM now has 2 Ampere range for AC Power.
pH calibration and sampling improved,
warning if temperature rises to damaging levels.
PEP can use two probes to measure
intervals, reflective mode corrected.

Module ID Numbers
David Ress delved deeply into the Demo program and noticed:
0x10 is TLp module
0x11 is Distance module
0xFF is empty
My guess, the module ID is on the front, notice the "10"?
Since they used FF, then the module ID is hex, that leaves
16 or less possible IDs to test for. If you know how to
probulate for the ID, when you get a new module, just test
for ID and increment +1 for each iteration.
I would expect that each module has an EPROM (remember,
90-94 technology) that has module identification. Not likely
that module characteristics are stored in the base unit,
because what little I see does not suggest any base unit
David Ress thinks the ID might be hardware. When I crack a
module open, we'll get a better idea.
Serial Port Address
The PSL device driver (PSLDEV1.SYS) uses the IBM PS/2 family
communications port standard for the address and interrupts
COM PORT HEX ADDRESS IRQ
The cable that comes with PSL is made to connect to a 25-pin
D-Shell. If your computer has a 9-pin D-Shell, you can buy a
9-pin to 25-pin adapter. Radio Shack has one with part
number 26-209. IBM has one also, with part number 6450242.
"PSL device drivers are available in the Users Guide that
allow highly technical customers to program their own
The normal install program sets the device driver statement
in CONFIG.SYS as follows:
DEVICE=C:\PSL\PSLDEV1.SYS /n:12 or C:\PSL\EXPLORER\PSLDEV1.SYS /n:12
The /n:12 enables COM ports 1 and 2 to run PSL. If the mouse
is connected to COM1 change the device driver statement to:
DEVICE=C:\PSL\PSLDEV1.SYS /n:2 or C:\PSL\EXPLORER\PSLDEV1.SYS /n:2
Now PSL can only be run on COM2.
PSL Modules and Accessories
w/Motion & Mechanics Module 57F7922
(M&M module) (yellow box)
Non-invasive, non-contact distance
measurements using an ultrasonic sonar transducer. This
probe is ideal for a wide range of experiments from
physics to human physiology and is very popular for use in
teaching mathematics. The patented PSL housing design
provides fast, easy setup in the classroom. Measurement
range is 0.4 to 10 meters.
The Distance Probe uses the same technology that Polaroid
Cameras and similar devices use to measure the distance to
an object. In the case of the camera, the distance-sensing
device allows the camera to use the appropriate settings
to take a focused and normally exposed picture. The
Distance Probe uses this technology to make similar
calculations with an accuracy of ± 7 mm over its entire
temperature range (0 ºC to 52 ºC).
The range of the Distance Probe is 0.4 m to 10 m. Your
Distance Probe uses ultrasonic pulses (sound) to measure
the time it takes to send out a pulse and wait for that
sound wave to bounce off an object and return to the
source-the Distance Probe.
Multimeter Module w/Leads 04G5956 (DMM
A fully-isolated digital multimeter
that can measure AC and DC voltage and current,
resistance, frequency and AC true RMS. The DMM can measure
voltage and current simultaneously to provide measurements
of power. The unique ability to measure current as easily
as voltage makes many experiments that were impossible,
possible. The DMM is also an easy way to adapt other
probes or inputs to a PSL system. The meter is fully
protected against overload and includes high-flexibility
red and black test leads. Voltage ranges to 40 volts,
current to 2 amperes, resistance to 40 MΩ and frequency to

Force Probe (only)
PSL7501 (DMM module)
provides a 12 mm "cup" that is used to hold a standard 000
size rubber test tube stopper or other impact target. This
stopper is used as an elastic surface for studies of
forces occurring during impacts.
Table Adapter provides
a smooth, flat, 22mm diameter surface for the sensor tip.
The adapter is machined from high-strength stainless steel
and simply slips over the sensor tip.
Can you attach the PSL Force Probe to a

that generates the -5 volts would be required. Team Labs
may produce this if there is interest.
