INTRODUCTION
Introduction to the Digidata 1322A
The Digidata 1322A is a high-resolution, low-noise digitizer intended for precision
scientific applications. The Digidata 1322A digitizes at an aggregate speed of
500 kHz. It provides sixteen multiplexed, 16-bit analog inputs and two nonmultiplexed, 16-bit analog outputs. There are sixteen digital input lines and sixteen
digital output lines, as well as Tag and Start digital inputs.
The Digidata 1322A communicates with the host computer through the SCSI bus.
To minimize the likelihood of installation or performance problems, every Digidata
1322A is supplied from the factory with a SCSI adapter card that should be
installed into the computer, although you may choose to use an existing SCSI port.
The Digidata 1322A is compatible with both the Windows and Macintosh operating
systems. It is a plug-and-play device; it is automatically recognized by Windows
95, 98, and 2000. The Digidata 1322A is supported by Clampex 8, AxoScope 8,
and AxoGraph 4.2 (and higher versions). AxoScope is an easy-to-use, full-featured
data acquisition program for Windows that is provided free with the Digidata.
The Digidata 1322A has higher speed, lower noise and better resolution (greater
dynamic range) than the previous Digidata 1200 models. New features also include
better instrument telegraph support and line-frequency triggering.
The Digidata 1322A is intended for benchtop use, but it is supplied with a simple
rack-mount kit.

Notes on the SCSI Adapter Card
One SCSI adapter card is provided with every Digidata 1322A. Be sure to read the
SCSI Adapter Installation Guide. Some users may prefer to use an existing SCSI
port on the computer. While it is possible to use other models of SCSI adapters,
Axon Instruments can provide technical support only for the SCSI adapter bundled
with the Digidata 1322A. The Digidata 1322A is compatible with the popular
Adaptec SCSI adapter cards. The Digidata 1322A and cable use high-density
50-pin connectors. You may need a special adapter or cable to connect to a SCSI
adapter with a wide-SCSI connector (e.g., Adaptec 2940W or 2940UW).
Rack Mount Kit
The Digidata 1322A is designed to be a desktop unit. However, some users may
want to mount the Digidata 1322A in a rack, so a Rack Mount Kit is provided.
The Rack Mount Kit includes the following parts:
One Rack Mount Panel
Two Side Brackets with set screws

TROUBLESHOOTING
Functional Checkout
Step 1
If you are able to configure the Digidata 1322A in either AxoScope or Clampex
then the Digidata 1322A is properly installed. Go to Configure/Digitizer. Choose
Digidata 1320 in the Digitizer field and then press the Configure button. The
Configure Digidata 132x dialog reports which digitizer is installed (1320A, 1321A,
or 1322A). It also displays the SCSI ID number and the serial number of the
device. The Power-on Holding Levels section is used to set the voltage on both
Analog Out channels at the time that the Digidata 1322A is turned on. The initial
Digital Out levels can also be set high or low by clicking on the check boxes above
the numbers corresponding to each digital output (a check means high, blank means
low).
Step 2
Check to make sure that you have a proper ASPI driver installation on your system.
This should have occurred during the installation of AxoScope or pCLAMP 8. Run
aspichk.exe (found in the ASPIChk folder under the WinASPI folder on the
AxoScope 8 or pCLAMP 8 CD). If you do not have the latest ASPI drivers
installed on your computer, or if you have an improper configuration, ASPIChk
will tell you. In this case, open the I386 folder (also under the WinASPI folder)
and run aspiinst.exe to install the WinASPI files.
Chapter 3
10 • Troubleshooting
Step 3
Check that the Digidata 1322A and SCSI card are properly installed. In Windows
95/98, go to Start Button/Settings/Control Panel/System/Device Manager tab. The
figure shows an
example of the
Device Manager
window. First, click
on the plus (+) sign
next to Axon
Instruments. You
should see Axon
Digidata 1322.
Then, click on the
plus sign next to
SCSI controllers.
You should see the
label for the SCSI
adapter card
shipped with the
Digidata 1322A.
Double-click on the
SCSI adapter entry
to see the device
status.
Windows NT 4.0
users can verify the
correct installation of the SCSI adapter in a similar manner by going to Start
Button/Settings/Control Panel/SCSI Adapters, and looking at the SCSI adapter list.
In Windows 2000, go to Start Button/Settings/Control Panel/Administrative
Tools/Computer Management/System Tools/Device Manager. The Device
Manager is the same as in Windows 95/98.

Troubleshooting
If you have any problem with the operation of the Digidata 1322A, follow this
section to check out some possible problems and solutions. If your problem is still
not resolved, please go through the "Before You Call" checklist below prior to
contacting us.
1. If you suspect that the Digidata is not working properly, isolate the problem!
Disconnect any external instruments and test the Digidata by itself. If you
suspect problems with the analog or digital outputs, use a voltmeter or
oscilloscope to monitor the signal. If you suspect a problem with the analog or
digital inputs, hook up a known signal source such as a signal generator, or even
the analog output if you know it is working properly.
2. The Power light on the front panel is off.
Check the fuse. The fuse box is found in the middle of the Power Unit on the
rear panel. Simply remove the power cord and then reach underneath the fuse
box to open.
3. The screen shows a straight line instead of the input signal.
Are all external connections properly made? Check cables for continuity
problems. Make sure the SCSI cable is securely attached to both the card and
the interface box. Try rebooting the computer and restarting the Digidata.
4. Noise is introduced when the data is digitized.
If noise is added to the signal on the analog input, make sure that all cables are
routed away from switching power supplies, power cords, monitors, or any other
major sources of noise. Check for proper ground connections. See below for
more information on proper grounding practices.
5. The Ready light on the front panel flashes continually during operation.
The Digidata 1322A is in a problem state. Call Technical Support at Axon
Instruments for a Return Merchandise Authorization (RMA) number before
returning the unit for repairs.
Chapter 3
12 • Troubleshooting
6. The Digidata does not work at all or it locks up the computer when doing
certain operations.
Try resetting the Digidata by turning it off and then back on. Then reboot the
computer. Refer to the SCSI Host Adapter Installation Guide to verify that the
SCSI adapter card is installed properly. Call Technical Support at Axon
Instruments if the problem persists.
7. In Clampex 8, the Digitizer Gain cannot be changed.
This is possible with the 12-bit Digidata 1200A/B. The Digidata 1322A does
not include a programmable digitizer gain. The higher 16-bit dynamic range and
lower noise makes a programmable gain unnecessary.
8. When troubleshooting the Digidata or your software, it is best to simplify your
software configuration by turning off all other programs. It may appear that
there are no other programs running in the background. However, this may not
be the case. To see if other programs are running in the background click on an
empty place on the desktop and then press Ctl-Alt-Del (holding these three keys
down at the same time). This will open the Task Manager in Windows 95 and
98. In Windows NT 4.0 and 2000 you then need to click on the Task Manager
button. Close all unnecessary programs running in the background.
Hint: For optimal acquisition performance in Clampex and/or AxoScope do the
following:
1. Configure/Lab Book OptionsÆ select Never log any events
2. Configure/Program OptionsÆ select Disable screen saver during data
acquisition

Grounding and Minimizing Noise
To avoid ground-loops, we recommend that you plug-in the Digidata 1322A to the
same power-strip as the PC. Also, be aware that each Analog Input BNC on the
Digidata 1322A is a single-ended input (all BNC shells are connected to signal
ground).
When noise in the system occurs, the first step is diagnosis. Take ALL instruments
out of their racks, and connect them together with only ONE BNC connection.
Observe if the hum (50 – 60 Hz noise) is eliminated. Also observe if the hum is
produced by pickup from the headstage by shielding the headstage and watching
the magnitude of the hum.
If the hum is eliminated at this step, then connect the second BNC cable. If hum is
now observed, this is probably a ground loop that is picking up an alternating
magnetic field. Next try to eliminate the source of the alternating magnetic field: a
cheap transformer, an electric motor, such as found in a nearby fan or refrigerator.
Try to rearrange the two BNC cables to determine if their positioning tells you
anything about the source of the alternating field. High frequency components (20
to 50 kHz) may also appear if there is a ground loop. These originate from the
switching power supply of the computer and can be picked up in the analog signal
inputs of the Digidata 1322A.
If removing the source of the alternating field is not possible, eliminate the ground
loop by making one of the connections between the two instruments without a
shield. Make this either with a naked unshielded wire, or with a BNC cable that has
its shielding cut at one end. Make a break in the shielding away from the interface,
near the connection on the instrument suspected of creating the ground loop.
For users of Axon Instruments amplifiers, more information regarding noise
reduction procedures can be found in the manuals for the Axopatch 200B,
Axopatch-1D, and AxoClamp-2B.
Chapter 3
14 • Troubleshooting
Before you call…
Please write down the following information before you call for technical support.
This information can help us identify possible problems and will quickly expose
known conflicts.
1. What is the serial number of the Digidata? The serial number is on a small barcode sticker on the back panel.
2. Gather the following computer information: The brand and model of computer
you use; the type (e.g., Pentium II) and speed of the microprocessor (e.g.,
300 MHz); how much RAM is installed; which operating system is loaded
(Windows 95, 98, NT, 2000).
3. What other cards are installed in the computer (e.g., network, sound, SCSI,
etc.)? If possible, find out what I/O addresses, DMA channels and IRQs are
being used.
4. Clampex users: connect Analog Out 0 to Analog In 0. Then run an Episodic
mode protocol with a waveform specified. Do you see the waveform when you
hit the view button?
5. If you can reproduce a problem by following a series of steps using software,
record these steps so that we can reproduce the problem.
After following these steps, call Axon Instruments at 510-675-6200 or send e-mail
to: tech@axon.com.

Chapter 4
INTERFACE DESCRIPTION
Front Panel
The front panel connectors are all BNCs. There are two LEDs: POWER and
READY. Upon power-up, the READY LED will blink for a few seconds, then it
should remain on continuously. If it does not, please see TROUBLESHOOTING in
Chapter 3.
Chapter 4
16 • Interface Description
Analog Input
There are sixteen 16-bit analog input channels. The BNC shields for the Analog
Inputs are connected to the Analog ground. Each channel has a buffer amplifier to
drive the analog multiplexer such that cross-talk between the inputs will be
minimized.
These input channels are used to digitize signals for Clampex or AxoScope.
Analog Output
The front panel has two 16-bit analog output channels. The average output noise is
150 µV peak-to-peak in a 10 kHz bandwidth measured with a single pole filter
(with no voltage command applied). Each channel has an operational amplifier to
buffer the output signal of the D/A converter. The two analog output channels can
be used simultaneously for waveform generation in Clampex.
Digital Output
Digital Outputs 0-3 are found on the front panel of the Digidata 1322A. The 5 V
CMOS level can be used to trigger external devices and the control is provided in
Clampex.
Trigger In
TAG and START are digital inputs compatible with TTL-level signals. The TAG
input can be used to mark events (e.g., perfusion ON) in Clampex and AxoScope.
The START input can be used to begin data acquisition.
Digidata 1322A Operator’s Manual, Copyright 2000-2001, Axon Instruments, Inc.
Interface Description • 17
Rear Panel
There are several sets of connectors on the rear panel of the Digidata 1322A: ten
BNCs, two 25-pin connectors, one 15-pin connector for peripherals, and two SCSI
connectors.
Telegraph Inputs
The Digidata 1322A has a dedicated 12-bit A/D converter that provides four
telegraph input channels on the rear panel. These telegraph input channels provide
gain, frequency or capacitance values from Axon Instruments amplifiers (i.e.,
Axopatch 200B). These inputs are independent of the 16 analog input channels.
Digital Outputs
Digital Outputs 4-7 are found on the rear panel of the Digidata 1322A. Therefore,
there are a total of eight Digital Output BNC connectors provided by the Digidata
1322A (four on the front panel and four on the rear panel). The CMOS level
outputs are set to high (+ 5 V) or low (0 V). They can be used to trigger external
devices and the control is provided in Clampex.
Chapter 4
18 • Interface Description
Trigger Output
This will support specific trigger output functions in pCLAMP 9.
Line Frequency Output
Line voltage frequency output is available from this BNC. This CMOS logic-level
output provides a 50-60 Hz digital signal (square pulse) that represents the
frequency from the AC mains power. This signal can be used to trigger external
devices at the line frequency. If you wish to trigger the Digidata synchronously
with the line frequency, it is preferable to use the internal line frequency trigger
which can be selected as one of the trigger sources in the Clampex or AxoScope
software.

SCSI ID
This number identifies the SCSI device ID of the Digidata 1322A. The factory
default setting is 4. All devices on the SCSI bus must have a unique ID.
SCSI Ports
On the rear panel there are two SCSI ports, which are identical. Either one is OK
for connecting the Digidata 1322A to a SCSI host adapter card in the computer via
the SCSI cable. The additional port is for connecting additional SCSI devices to the
SCSI bus.
Chapter 4
20 • Interface Description
SCSI Termination
The Digidata 1322A’s SCSI-2 interface comes with active termination on-board for
reliable and high-speed data transfer. The switch on the rear panel provides for
enabling and disabling termination. We recommend that this switch remain in the
ON position. In a SCSI bus, only the devices at both ends of the bus require
termination. If there is more than one SCSI device on the SCSI bus, we
recommend that the Digidata 1322A be placed at the end of the SCSI chain.
Power Supply
The power supply is universal input. Therefore, both 110 and 220 V power sources
are OK to use.

STANDARD WARRANTY and
REPAIR SERVICE
Standard Warranty
Axon Instruments warrants its non-consumable hardware products to be free from
defects in materials and workmanship for 12 months from date of invoice. The
warranty covers the cost of parts and labor to repair the product. Products returned
to our factory for repair must be properly packaged with transportation charges
prepaid and the shipment fully insured. We will pay for the return shipping of the
product to the customer. If the shipment is to a location outside the United States,
the customer will be responsible for paying all duties, taxes and freight clearance
charges if applicable.
The warranty is valid when the product is used for its intended purpose and does
not cover products which have been modified without approval from Axon
Instruments, or which have been damaged by abuse, accident or connection to
incompatible equipment.
To obtain warranty service, follow the procedure described in the Repair Service
section. Failure to do so will cause long delays and additional expense to the
customer.
This warranty is in lieu of all other warranties, expressed or implied.
