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 non-
multiplexed, 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
Four Screws
Refer to the figure on the next page and follow these instructions for installation:
1. Remove the bezel (the frame that surrounds the front panel)
a. Use one finger to pull one side of the bezel outward (see figure) to unhook it.
b. Remove the bezel.
c. Do NOT remove the front panel!
2. Mount the Side Brackets
a. Before inserting the Side Brackets, loosen the screws on the front panel (to
allow clear access to the grooves on the side panels).
b. Insert one Side Bracket on each side of the Digidata 1322A.
c. Tighten the screws on the front panel.
d. The Side Brackets should be free to move along the grooves of the side
panels.

3. Attach the Rack Mount Panel
a. Slide the Rack Mount Panel around the front panel.
b. Snap the bezel back in place around the front panel.
c. Pull the Rack Mount Panel flush up against the bezel.
d. Position the Side Brackets up against the Rack Mount Panel.
e. Use the four Screws to secure the Rack Mount Panel to the Side Brackets.
f. Tighten the Side Bracket set screws up against the side panels.
4. Secure the entire unit in the rack
a. Place the unit (Digidata 1322A) plus the attached rack mount assembly in
the rack.
b. Secure the Rack Mount Panel to the rack with four rack screws (not
included).
