1 GENERAL

The Basile 2600 Multifunction Printer is a microprocessor controlled device designed to
acquire C
out on thermal paper in real time or saved in the internal memory be unload later on.

The 2600 Multifunction Printer is also provided with a RS232C connector, located on the
back panel, in order to route Data to PC in real time or to unload them later on. Basile
WIN-DAS software is required (IBM compatible, Windows 95 or 3.1).

This makes the 2600 be a REAL MULTI-PURPOSE FLEXIBLE INTERFACE between the
instruments linked to it and any IBM or compatible PC.

Each channel can acquire Data from instruments which supply a Counting or Timing TTL
signals such as :

And a number of other Basile instruments or other makes.

OUNTING OR TIMING DATA OF SIX INDEPENDENT CHANNELS. The Data can be printed-

7550 Passive Avoidance
6650 Hole Board
7370 Plantar Test
7360 Tail Flick
7250 Hot Plate
7600/50 Rota Rod for Mice (requires 5 channels)
7700/50 Rota Rod for Rats (requires 4 channels)
7402 Activity cages
7210 Analgesy-Meter (model provided with optical switch)

The 2600 Data print-out represents Counting or Timing events. Counting may be suitable
for Hole Board, Activity cages, etc, Timing for Plantar Test, Hot Plate, Rota Rod, etc.

Counting mode results are printed-out at preset intervals, whereas Timing mode results can

be set for single pulse or cumulative operation. Cumulative time interval are referred to a
preset interval.

The 2600 includes a Graphic display, a 4 button keyboard and the printer proper.
The Graphic display monitors all available commands settable by the operator by simply

acting on the 4 button keyboard located just below it.
A red push-button switch located on the left top of the front panel, if depressed, push the

chart a step forward.

1.1 CONNECTING AN INSTRUMENT TO THE SERIAL INPUT

Besides the described features, the RS232C input can accept signal from instruments
already provided with Serial connector like the Basile Plethysmometer 7140.

A data string, for instance of a 7140 linked to the 2600 Serial connector, is directly printed
on the paper with indication of the corresponding address of the instrument which
generates it.

This string does not interfere with any of the 6 available input channels which remain fully
operative.

Obviously, when the RS232C connector is used for linking another instrument (7140), the
PC communication can not be activated.

The instrument connected to the Multifunction Printer via the RS232C input, in our case the
Plethysmometer 7140, must be set in order to channel output Data to its Serial path (see
corresponding Instruction Manuals).

1.2 2600 INPUT CONNECTOR

The input 15 pin Delta connector for linking external TTL signals to the 2600 Multifunction
Printer is located on the rear panel of the unit.

The 2600 Multifunction Printer is generally purchased for specific instruments and it
comes already provided with suitable connection cables for these apparatus. In case the
researcher has to make out his/her own input connections, please pay attention to the
following considerations.

The TTL signal applied is active on the low level which corresponds to Zero Volt.
To make activated the 2600 ON input channels it is sufficient a make contact (short circuit)

between the corresponding channel connector pin and the Common. In this way, the
internal pull-up, stand-by at 5 Volt, drops to active TTL low level ( 0 Volt ).

Common = pin 1
Channel 1 = pin 10
Channel 2 = pin 3
Channel 3 = pin 11
Channel 4 = pin 4
Channel 5 = pin 12
Channel 6 = pin 5
VDD = Pin 9

Pin 9 is the positive 5 Volt (VDD) of the Multifuncion Printer power supply; be careful not to
short pin 1 (Common) and pin 9 (+5V) .
Positive 5 Volt may be useful to feed an external inverter in case an applied input signal is
operative on the high TTL level (level 1 = 5V) instead of Common level.

2 INSTALLATION OF THE 2600 MULTIFUNCTION PRINTER

Once the instrument has been unpacked, check the completeness of the shipment, packing
list to hand, and visually inspect the instrument parts soon.

If some part is damaged or, after having tested the complete assembled instrument, if fails
to meet the rated performances, notify our company immediately.

Before applying power, consider on the back side of the 2600 the Power Module which
includes the Mains Switch, the Fuse Holder, the Voltage Selector an the Inlet Connector of
the Mains Cord.

Pay particular attention to the Mains Voltage set and shown in the small flag of the Power
Module.

Before any operation of Fuse replacing or Mains Voltage modification Remove the Mains
Cord.

Make sure that only fuses with the required rated current and of the specified types are
used for replacement.

2.1 SWITCHING ON

Turn the Multifuncion Printer ON by acting on the Mains Switch placed on the back side of
the instrument, the software takes some seconds to perform a complete checking of any
electronic circuit, in the meantime a mice picture is monitored and then the display shows
the previous experiment setting.

The previous setting configuration, the Date and the Time are saved in the internal
memory of the microprocessor which is fed by a couple of watch type batteries.

In case the following message appears :

The two batteries are out of order; they must
be replaced (see page 21) and the Date and
the Time must be set again.

2.2 PAPER LOADING

Lift up the lid of the thermal paper receptacle (on the left side of the top panel) by lifting it
up.

Remove the run-out chart and bobbin.
Place a fresh roll into the Printer block with the sensitive side (shine side) down. Chart

shine side must be facing you once the paper comes out.

V-cut , with a pair of scissors, the beginning of the chart roll and insert it into the printer
narrow rectangular slot located at the back of the printer body.

With instrument ON, depress the red PAPER FEED push-button switch placed on the top
panel (left side) until the chart comes out.

Shut the lid. Exert care the paper pass through the rectangular slot located on the lid.
If printing does not take place, check that the paper roll has not been loaded upside down;

the thermal sensitive side is one only.

3 DISPLAY AND KEYBOARD

The Graphic display is located at the right side of the instrument and the keyboard is just
below it.

The keyboard consists of 4 soft push-button
switches marked F1, F2, F3 and F4.

The meaning of them depends on software
sub-routine in which we are working

AND on

the display corresponding label just above its
key.

For instance, the F2 key, while in the Main
Menu is labelled FNC (Function menu), once
depressed, it acquires the meaning of CLK
(Clock). The clock is the software level where
the operator can set the Time and the Date.

The F4 key, in most cases, is labelled ESC (Escape); it enables the operator to abandon
a just set wrong selection or to leave the sub-routine in which he/she is working in order to
go back to the previous software level.

The display labels are, for obvious reasons, shortened. Please refer to the following list :

ALL all (Serial + Printer)
B-R baud rate
CLK clock setting
CNT Counting mode
DAT Date setting
DIS display contrast
ESC escape
FNC function menu
FTR feature setting
MEM memory menu
NO no
NUL annulment
OFF channel inactivation
ON channel activation
OK confirmation
OPR operation channel menu (timing or counting mode)
OUT output menu (path and features)
PAT output path (PC and/or printer)
PRN Data printing selection
REP automatically repeat the previous channel mode
RES Data memory reset

SER serial (PC) path
TIM Time setting
TMR Timing mode
VW Data view
YES yes
I-P Intermediate Printing

In almost any software menu, the intermediate display level, in the middle of the screen,

SHOWS THE LAST RECEIVED DATUM IN REAL TIME, no matter if it is saved in the memory only or

Printed and/or sent to PC. This Datum is completed with the experiment feature (sequence
number, sex, etc.) if preset.

3.1 MAIN MENU

The Main Menu shows the Ugo Basile logo and, at the bottom of it, the boxes referred to
the soft keys respectively labelled : OPR, FNC, MEM & ESC.

The F4 ESC key, if depressed more times while in the Main Menu, generates a loop
showing, in sequence : Basile release of the installed software, selected output path,
channel status and mode, Date & Time, real time Data in progress of each channel and the
mice picture.

The selected output path and the Channel status & mode are reported in the upper side of
the graphic display.

PRN and/or SER labels indicate that the corresponding output path has been set. PRN
means real time Data printing and SER means that the serial communication to PC has
been activated.

Please note that any received Datum may be printed in real time or not; in any case it is
saved in the internal microprocessor memory, able to store up to about 500 measurement
strings (each string includes Data and Time & Date indication).

The activated channel status is displayed following path indication (PRN and/or SER). The
small type letter at the foot of the channel labels indicate the mode setting : “t” means
Timer, “c” is Counter and “ct” means Cumulative Timer.

The Counting mode means to record the total number of events in a preset printing
interval (Hole Board, Activity Cage, etc). Timing mode means to record the duration of a
single pulse (Passive Avoidance, Plantar Test, etc). Cumulative Timer means the sum of
all the latencies occurred during the preset interval (many Behavioural experiments,
Cumulative Rota Rod trials, etc).

The activated channels are listed with real time Data indication in the last step of the Main
Menu loop, just before going back to the mice picture.

The Data string shows, for any activated channel, in order from left to right: the input
channel number among the 6 available, the Datum itself in 5 digits (3 integers and 2
decimals for Timing mode and 5 integers figures for Counting mode) and the elapsed time
expressed in minutes (2 digits) from the beginning of the trial in progress.

Moreover the Data string may also show some experiment features (animal number, sex,
etc.) if preset.

These real time Data indication is updated at intervals of about 1.5 seconds. In case the
researcher likes to follow very fast events, he/she has to set a configuration in which, the
last received Datum appears in the middle of the display.

The LAST RECEIVED DATUM IS SHOWN in intermediate display section in the most of
the working menus and it is updated very fast.

The 2600 Multifunction Printer can do much more of what listed in the table, please refer to
the indicated manual pages for more information.

3.3 OPERATION (OPR) MENU

From the Main Menu depress the F1 OPR .

By the F1 REP the operator can repeat the previous experiment having the same
configuration. This saves time and reduce the risk of a wrong setting. This operation ALSO

RESETS

the printing interval (and the corresponding counter) in case it is already in

progress.

IMPORTANT: Please note that, if a previous session has been aborted by the OFF key
before its programmed end, the REP key does not work and the following experiment
should be planed again.

By the F3 I-P key, an Intermediate Printing will be carried out. It is referred to the set
channels, the Data shown are updated on the last minute, and the time indicated is the
elapsed interval since the session has been started.

By the F2 CON key the Researcher can set an experiment with a fresh configuration
(different than the previous session).

At this point the display will ask the operator to set how many channels he desires to switch
On.

The display will show :

By the F1 UP arrow the operator can scan, in a defined loop, all the 2600 available
channels and to read their status (including ch. Features, if set) On the screen.

The F1 UP key, at the end of the 6 channel loop, shows the label “ALL” in which the
operator can set all the channels with the same configuration instead of wasting time in
setting them step by step.

For any highlighted channel (or ALL), the researcher can select F2 ON in order to have
the channel activated or F3 OFF to turn it Off.

By the F3 (OFF) key a cage may be inactivated. If a session, related to this cage, is in
progress, the corresponding experiment will be aborted.

Once the F2 ON key has been depressed, the Display will show :

The fresh F3 CNT key enables to set the channel in question (displayed on the screen)
for Counting mode, the F4 TMR key for Timing configuration.

A

If F3 CNT key for Counting mode has been set the display will ask the operator to set the
related Printing Interval.

ct on the F1 UP & F2 DOWN keys to set the Interval expressed in minutes and

highlighted in the middle of the monitor.

Confirm the selection made by the F3 OK key .

The F4 NUL key aborts this software level and the program goes back to the previous
menu.

The operator can now select if to have an experiment of a certain number of trials (for
instance 3 print-out reports of 10 minutes each) and then to switch the channel OFF or to
leave the Data acquiring untimed.

The untimed mode, settable by F4 NUL key, leaves the experiment go on with regular
print-out results at preset intervals since the channel is manually switched OFF.

The F1 and F2 arrow keys, enable to set the number of trials at the end of which the
channel is automatically turned OFF. Confirm the choice with F3 OK key.

TO REPEAT THE SESSION, DEPRESS, FROM THE OPR MENU THE F2 REP KEY.

The Interval period starts exactly at the instant when OK or NUL keys have been
depressed. if this operation is performed with a Printing Interval in progress, it will
automatically reset.

Going back to the OPR menu, the operator can set the Timing mode by the F4 TMR key.
The operator is required to set the channel for Cumulative measurements or not.
Answer with F3 YES or F4 NO keys.

In case of Cumulative Timing mode, the researcher has to set the printing interval
expressed in minutes and, if desired, the number of trials, as already described above for
the Counting configuration.

Remind that the F3 OK or F4 NUL keys start the Interval period exactly at this time. The
interval period is automatically reset if already in progress.

We remind that the Status of any activated Channel is displayed in the upper part of the
monitor.

The above operations (channel ON/OFF and TMR or CNT mode) must be repeated for any
channel in which the operator is interested. To set all the channel with the same
configuration is advisable to select the ALL condition which allows to save time and
reduces the risk of mistakes.

Once an experiment is over, for instance a trial of 6 sessions of 10 minutes each, the
operator, instead of wasting time in setting it again, can simply enter the OPR menu, select
the channel in question and depress the F2 REP key. A fresh trial, identical to the previous
one, will start exactly at this time (an experiment already in progress will be automatically
reset).

TO SWITCH A CHANNEL OFF IT IS NECESSARY TO SELECT THE OPR MENU, TO SET WITH THE UP

ARROWS THE DESIRED CHANNEL NUMBER AND TO DEPRESS THE F3 OFF KEY.

3.4 HOW TO SET THE DATA OUTPUT PATH

If no path is set, the acquired Data are saved in the Multifunction Printer memory only. In
order to set real time printing or to enable the real time or remote communication with the
PC, depress, from the Main Menu, F2 FNC key followed by the F1 OUT key. The
display shows :

Select now the F1 PAT key; the display
will show :

The F1 PRN key enables the operator to
print in real time the Data of the activated
channels.

PRN status and any activated channel are
displayed at the top of the monitor.

Once F1 PRN key has been depressed and real time printing has been set, the operator
may acquire the intermediate Data of the activated channels which are displayed at the
top of the screen.

By the F3 YES key the INTERMEDIATE PRINTING takes place and it does not interfere
with the Data and the Interval in progress. Select this option any time an INTERMEDIATE
DATA PRINTING is required.

By the F4 NO key the researcher can avoid the Intermediate Printing and leave this sub­routine. Anyway the real time printing is already set.

The F2 SER key allows direct
connection with the PC for exporting
Data in real time or in a remote condition.
Serial communication between the 2600
and IBM or compatible PC is owned by
the Basile WIN-DAS software (not
supplied with the instrument). Ask for a
demo diskette.

In case an instrument, for instance a
Basile Plethysmometer 7140, is linked to
the serial connector of the Multifunction
Printer, bear in mind that the
Plethysmometer must be set in order to
channel Data into its serial path.
In this configuration PC communication

UGO BASILE Biological Research Apparatus

is not possible.

The F3 ALL key enables the researcher to select both output paths simultaneously, the
Printer and the Serial.

The 2600 output path status is highlighted in the upper part of the display by lighting PRN
and/or SER labels.

In case the operator wants to SWITCH OFF one of the previously activated choice (Printer
and/or Serial path), it is necessary to enter again the PAT menu and depress the F4 ESC
key, selecting no option.

When the SER or ALL functions have been activated, the PC must be correctly connected
to the 2600; if everything is OK the display shows the activated communication with the
following message :

From this menu the operator can set the address of the Multifunction Printer which sends
Data into PC and the communication speed (Baud Rate).

The default address is 01. Default Baud Rate is 300.

In case the factory set parameters are OK, as it happens in most cases, the operator can
simply depress the F4 ESC key in order to leave this menu and the following setting is not
necessary.

To modify the Address, if necessary, press the F1 ADD key, select with the arrows the
desired value between 01 and 99 and then depress the F4 ESC key.

To change the factory set Baud Rate depress the F2 B-R key. Select by the arrows the
desired value in the loop which includes 300 - 600 - 1200 - 2400 & 4800 Bps. Then
depress the F4 ESC key.

The Baud Rate must be identical to what set in the Basile WIN-DAS software.
Basile WIN-DAS software has been designed for IBM or compatible PC provided with

Windows 95 or 3.1 operating system.

3.5 HOW TO SET A CUSTOMISED EXPERIMENTAL CONFIGURATION

From the Main Menu, depress the F2 FNC key followed by the F1 OUT key. The
display will show :

Depress now the F2 FTR key, the display shows:

The FTR (Feature) menu enables to personalise the basic Datum, consisting of a
Counting or of a Timing event, by adding some information :

Sequence number
Experiment number
Sex of the animal
Left or right paw (not in the “ct” mode)

The operator is required to answer Yes or No at the question “CHANGE FEATURE ?”
which is referred to the channel (ch. 3 in our case) displayed in the intermediate level of
the monitor.

To scan all the available channels, just act on the UP and Down keys and read, in the
intermediate display level, how, at the moment, that channel is set. The intermediate string
of the monitor shows the number of the channel in question, the Data format, the interval
indication and the feature already set.

This loop includes all the available channels and a seventh choice labelled “A” (ALL) which
enables to set the all 6 channels with the same configuration instead of wasting time in
setting each of them step by step.

Answer, for any channel which it is being used, YES if the corresponding configuration has
to be modified and NO if it is OK.

To set features the researcher has to scan the whole loop which includes all the available
selections; enter the information required step by step and confirm the highlighted value by
depressing the F3 OK key. If one or more options have not to be considered, simply
depress the F4 NUL key.

To ERASE one or more features previously set, it is required to enter this software level, to
highlight the related label box and to depress the F4 NUL key.

By depressing the arrow keys shortly, the numerical value will increase or decrease of one
step. By keeping them depressed longer, the selection can be made out at higher speed.

The selected features will be kept in the memory even if the instrument is turned OFF.

Once answered Yes to the “CHANGE FEATURE ?” question, the display will show :

The first feature to be defined is the Sequence Number.

Use the F1 UP and F2 DOWN keys to set the desired Sequence Number (from 01 to

99) and then confirm it by depressing the F3 OK key.

The Sequence Number, shown in the Data string in the middle of the screen, will
automatically increased by one figure at any subsequent measurement.

It trips once a Datum has been fully acquired and recorded. The intermediate level display
string shows the fresh Sequence Number taken into consideration for next measurement.

To avoid the Sequence Number selection, just depress the F4 NUL key.

IMPORTANT. When the operator starts a fresh experimental session, he/she can continue
from the Sequence Number reached at the end of the previous trial or enter this software
level and set a new Sequence Number, for example starting again from 01.

Once the above selection has been confirmed by F3 OK key or avoided by F4 NUL key
the display automatically propose the second step of the Feature loop :

Experiment or Group Number.
From 1 to 9.

Confirm selection by F3 OK or avoid it with F4 NUL key.

Selection of the sex, M (male) or F (Female), of the animal which has to be processed.

Confirm with F3 OK or avoid with F4 NUL.

In Cumulative Timing mode the F3 and F4 keys close the feature loop and the program
goes back to the previous sub-routine.

Selection of the R (right) and L (left) paw, of the animal which has to be measured:

PS - This option is not available, for technical reasons, when operating in Timing
Cumulative mode.

Close the Feature loop by confirming the choice with F3 OK key or by avoiding it with F4
NUL key

The software goes automatically back to the Main Menu.

Left paw (R = right). Not in the cumulative Timing mode, if set.
Sequence number, this value increases of one step at any measurement, if

set.

In case the Data are sent to PC, each printed string begins with the address of the
Multifunction Printer 2600 which gathers Data. Default address is 01 if not modified by the
operator.

If the researcher has selected the remote condition printing of combined Data with the
corresponding Time & Date, this information appears on a second line:

01 2 003866 10 1ML12 Data string (01 = 2600 address, PC

only)

01 ’96-11-15 09:23:48a Date & Time

3.7 MEMORY (MEM) MANAGEMENT

Each received Datum, no matter if printed or sent to PC, is saved in the memory which has

capabilities of about 500 measurement strings. Each string includes Data + Time & Date

A

indication.

By depressing the F3 MEM key the display shows :

The F1 VW key enables the operator to visualise on the display the Data stored in the
memory, at each Datum is added the corresponding Time & Date of when it was acquired.

Use the UP and DOWN arrow keys to scan the Data: By momentarily depressing these
keys the displayed Datum shown will increase or decrease of just one measurement. By
keeping these keys depressed longer, the Data will be scanned at higher speed.

The F4 ESC has the usual function of abandoning a wrong selection or recalling the
previous software level.

The F2 OUT key enables the researcher
to export to the PC or to PRINT memory
Data previously collected; the display will
show :

t this point the operator has to confirm if
he/she is interested to combine each
Datum with the related Date & Time or
not. Answer with F3 YES or F4 NO keys.

If the researcher has selected the combined printing of Data with the corresponding Time &
Date, this information appears on a second line:

01 2 003866 10 1ML12 Data string (01 = 2600 address, PC

only)

01 ’96-11-15 09:23:48a Date & Time

In case the operator wants to interrupt the print-out response of the stored Data, he/she
has to depress the F4 ESC key for at least one second.

BEFORE STARTING A NEW EXPERIMENTAL SESSION, we suggest the operator to pay
attention to the following points :

 The memory may contain some Data saved after a previous trial. If it is the case, in

order not to further consider them, enter the proper software level and RESET the
memory.

 In case the animal sequence number has been set, it may be necessary to modify the

animal number, which otherwise starts from the last tested animal number of previous
experiment.

Going Back to the MEMORY menu, the F3 RES key enables the researcher to reset the
Data stored in the memory. This command can be useful, for instance, before starting a
new experimental session, if the operator prefers to delete the Data stored from previous
trials.

The operator is now required to answer F3 YES or F4 NO to the question : ARE YOU
SURE? This further question has been added to avoid accidental loss of all stored Data.

The Memory menu also automatically appears when the memory is fully loaded which
means it has reached its maximum capability of about 500 lines.

If, while acquiring Data, happens to see on the display a “MEMORY FULL” message, the
operator can act in three ways :

 The researcher who is not interested in considering the Data saved in the memory, may

simply depress the F3 RES (Reset) key and confirm by answering YES to the question
ARE YOU SURE ?

 In case the Data saved in the memory are necessary, proceed in order to Print and/or

send them to PC as already explained in this chapter.

 There is also the possibility to ignore the indication of Fully Loaded Memory and to go on

with the experiment by depressing the F4 ESC key. The Data onwards will not be
saved. Consider that, in this case, the memory remains fully loaded and the display

reminds it by showing the Full Memory message every time the 2600 is switched ON.

3.1 SETTING TIME & DATE

From the Main Menu depress in sequence the F2 FNC key followed by F2 once more
(now labelled CLK). The display will show :

Select F1 TIM to set TIME. Use the F3 horizontal arrow key to highlight, on the related
display string, the hour, minute, second or watch mode box which has to be modified.

Use now the UP and DOWN keys momentarily to increase or decrease the numerical
value of one step, depress them longer for higher speed selection.

Remind also to set the Clock Mode where :

00 = 24 hour mode
01 = anti-meridian time
02 = post meridian time

Once the TIME setting is completed, depress the F4 ENT key which saves it and goes
back to the Main Menu.

Follow the same procedure to set the Date, selecting the F3 DAT key.
Enter also the day of the week :

01 = Monday
02 = Tuesday
03 = Wednesday

04 = Thursday
05 = Friday
06 = Saturday
07 = Sunday

Depress the F4 ENT key to confirm.

3.2 DISPLAY CONTRAST
