Measurement Computing CIO-DAS6402/12 - Manual (Page 5)

1 INTRODUCTION
The CIO-DAS6402/16 and CIO-DAS6402/12 provide 32 differential or 64 single-ended inputs. They have sample rates as high as
330 kHz (100 kHz for the 16-bit version). Using a 100-pin connector, the CIO-DAS6402 board provides large channel counts
without the need for external expansion boards.
The installation and operation of all CIO-DAS6402 series boards is very similar. Throughout this manual we use CIO-DAS6402 as
a generic designation for the CIO-DAS6402/12 and CIO-DAS6402/16. When required, due to the differences in the boards, the
specific board name is used.
The board’s analog input ranges are entirely software-selectable in bipolar ranges from ±10 to ±1.25 Volts and unipolar ranges
from 0 to 10V to 0 to 1.25V. The A/D converter can be triggered externally, or internally based on edge or level trigger sources.
The board supports standard (post) and pre-trigger operation and so is capable of continuous, scheduled or event-triggered data
acquisition.
High speed data acquisition without the chance of a lost sample is assured by the boards’ use of the REP INSW data transfers and
the on-board 1-Kilosample FIFO memory. In addition to the analog input section, each board also provides two channels of analog
output, eight bits of digital input, eight bits of digital output, and a number of counter/timer functions.
All CIO-DAS6402 functions are fully supported by the Universal Library TM software package. This software provides upper level
programming support for all DOS and Windows based operating systems. The CIO-DAS6402 is also shipped with InstaCal TM , a
powerful and easy-to-use installation, test, and calibration software package.
We recommend that you install InstaCal TM before installing the board in your computer. The InstaCal TM operations will show you
how to set the switches and jumpers on the board.
2 SOFTWARE INSTALLATION
The CIO-DAS6402 has a variety of switches and jumpers to set before installing the board in your computer. By far the simplest
way to configure your board is to use the InstaCal
TM program provided as part of your CIO-DAS6402 software package.
InstaCal TM will show you all available options, how to configure the various switches and jumpers to match your application
requirements, and will create a configuration file that your application software (and the Universal Library) will refer to so the
software you use will automatically know the exact configuration of the board.
Please refer to the Software Installation Manual regarding the installation and operation of InstaCal TM . The following hard copy
information is provided as a matter of completeness, and will allow you to set the hardware configuration of the CIO-DAS6402
board if you do not have immediate access to InstaCal
TM and/or your computer. The locations of each of the switches and jumpers
are shown in the figures below.
