Last Time Buy Notice
– Board Products
November 7, 2003
Effective immediately, DATEL, Inc. will be phasing out its line of board-level data acquisition
products. We will accept last time buy orders until
February 28, 2004.
Final shipments must
be accepted by
June 31, 2004.
In addition, all repairs and technical support must be concluded
by
September 30, 2004.
Please contact DATEL Sales as soon as practical to schedule your
order.
If this Notice is received by Purchasing, Materiel or Procurement personnel, we strongly
encourage you to forward this to your Engineering, Administrative and Program colleagues as
soon as practical.
Models to be Discontinued - Essentially
all
DATEL board-level data acquisition products, all
board-level accessories and all board software are covered in this Notice. This includes:
All
ST-xxx
model numbers (Multibus I boards, example ST-711)
All
PC-xxx
model numbers (ISA bus boards, example PC-414)
All
DVME-xxx
model numbers (VME bus boards, example DVME-628)
All
CPCI-xxx
model numbers (Compact PCI bus boards, example CPCI-511)
All
PCI-xxx
model numbers (PCI bus boards, example PCI-416)
Please note that many older ST-xxx, DVME-xxx and PC-xxx boards are already on very
limited availability due to component obsolescence and other manufacturing issues.
Last Time Orders - Customers should contact the DATEL Sales Dept. (Mansfield, MA, USA)
directly to place orders and negotiate delivery schedules. Some products may require minimum
order quantities and/or extended delivery. This varies over time so it is difficult to give an exact
list of such products.
To assure supply,
we encourage customers to accept deliveries as soon as practical.
As
time passes, customers risk non-availability of an increasing number of products. After the
customer accepts final order acknowledgement, all orders placed will be firm and non-
cancellable.
Warranty - DATEL’s standard warranty terms apply
except the warranty period.
As the date
of last shipments approach, warranty support and repairs will terminate on
September 30,
2004.
Customers must immediately perform a functional inspection on any shipments near this
date. DATEL will have no technical or repair facilities after this date.
Technical Support - Since some DATEL engineering resources have already been reallocated,
support and repairs are currently limited and more will be withdrawn over time. We encourage
users to get all support issues settled as soon as practical.
Replacement Products - DATEL is not aware of any competitive manufactured products which
are
exact
replacements for these products. However, there are numerous items with similar
functions. These will require re-integration with your application.
Manufacturing Rights - DATEL is not offering manufacturing rights on these products. The
difficulty here is the complexity of technical support to fully transfer all comprehensive details of
manufacturing (including test fixturing, component specifications and device programming). Most
of these products would require considerable re-engineering by the user to resume production
outside DATEL. Nor will we retain spare parts after September 30, 2004. Volume users
should contact DATEL to discuss their needs.
*******
As very large volume component users ourselves who are subject to frequent component
obsolescence issues, DATEL sincerely regrets any inconvenience this Notice may cause our
customers.

NEW
Offering very high system speed, the PC-414 is a multi-channel
analog input board for ISA compatible computers. Input
bandwidth is available up to 5 MHz and may be sampled at up
to 10 MHz. A common motherboard is used, with the analog
section contained in a pluggable 2” by 4” module. This allows
for a family of several different Sample/Hold - A/D Converter
speed and resolution options by exchanging analog modules.
The analog input ranges of the A/D converter are selectable
as unipolar 0 to +10 V, or bipolar ±5 V, or ±10 V depending on
the model. Model PC-414E offers 16 single-ended or 8
differential high speed channels.
Models PC-414F, G, J, K, L, M, and P include a simultaneous
sampling section. This function acquires signals on parallel
channels at the same time. This prevents phase errors and
skewing of multichannel correlated signals. Applications
include high speed cross-channel computation, beam-former
coherency for sonar or acoustics, telemetry, multiple carrier
demodulation, and highly concurrent system testing.
A/D data passes to an on-board First-In, First-Out (FIFO) data
memory and then to the host computer bus interface under
software control. The FIFO acts to uncouple the precise
timing of the A/D section from the block-oriented data
transfers on the bus. The design can continuously collect
analog data with non-stop converter triggering while data is
simultaneously read from the FIFO. This allows the collection
of “seamless” wide-bandwidth signals of millions of samples or
greater. Functions such as FFT sampling cannot tolerate lost
samples without increases in “arithmetic” noise during
computation processing.
Data can be transferred to mass storage peripherals such as
disk or magnetic tape. Applications include long-baseline
studies in astrophysics, component life testing, and
anomalous pattern search.

PC-414
The FIFO data output may also be routed under host software
control to an on-board parallel data port instead of being sent to
the computer bus. This parallel burst channel data may be read
by an external processor at very high speeds and avoids
possible speed restrictions of the computer bus. The outport
uses a very simple ready/acknowledge transfer handshake which
is adaptable to any remote parallel port including DT Connect
®
.
See model PC-414COM using a DSP COMM port interface.
The analog section of the PC-414 is optimized for high signal
quality and very low dynamic noise. The PC-414 is ideal as
an FFT “front-end” or DSP quantizer for array processors.
The A/D conversion timing section is designed for accurate multi-
scan data acquisition. Software programmable timers control the
interval between each conversion and each multichannel scan.
A programmable sample counter allows sample blocks of
specified length independent of FIFO length. The timer/counter
section uses a precision on-board crystal clock. Timeout and
sample count activities may be monitored using I/O status
registers and/or programmable interrupts. The interrupt method
may be fully synchronized with software programmable DMA
transfers directly to host computer memory.
S/H - A/D triggering can originate from several sources under
software control. The internal timebase is the normal trigger
source although single conversions or scans may be directly
commanded by host I/O register writes. An external trigger
clock may also be used to precisely synchronize sampling with
external events. This external trigger may start a single
multichannel scan or “N” multiple scans separated by
programmable delays.
Analog sampling can also be level-triggered using an on-board
analog comparator and an external level input. The reference
trigger level to the comparator is derived from an on-board 12-
bit D/A converter. If preferred, the D/A converter may also be
used as a general purpose analog output channel.
The PC-414B, D, F, G, H, K, M, N, and P versions contain five
SMA coaxial signal connectors. Four connectors are for the
sampled analog channels. The fifth connector is used for
external timebase clock input, external analog trigger signal,
or for the analog output. The PC-414E, J, and L versions
contain 25-pin “D” connectors (DB-25S). The burst channel
parallel port uses an internal dual row header.
The computer interface conforms to the PC-AT bus structure.
All data transfers (control, status, and A/D data) use 16-bit
transfers. Interrupt level selection is done via software.
Interrupt servicing is generated for a variety of reasons such
as A/D data read, DMA terminal count, sample count
reached, FIFO half-full, or FIFO full.
A/D output data coding is right-justified two’s complement with
sign extension, if desired, straight binary coding can also be
selected making it directly compatible with high level computer
languages such as “C”, Visual C++, Borland C Builder, Visual
Basic, and others.
