Chapter 1
Introducing the PCI-DAS6013 and PCI-DAS6014
Overview: PCI-DAS6013 and PCI-DAS6014 features
This manual explains how to install and use the PCI-DAS6013 and PCI-DAS6014 analog and digital I/O
boards.
These boards differ in that the PCI-DAS6014 has two digital-to-analog outputs, while the PCI-DAS6013 has no
digital-to-analog outputs.
Both boards provide up to 16 analog inputs. Each input can be individually configured as single-ended or
differential. The analog inputs have 16-bit resolution.
The boards' input ranges are bipolar-only. They have four ranges of ±10V, ±5V, ±500mV, and ±50mV. The
ranges are software-selectable.
The boards provide nine user-configurable trigger/clock/gate pins. They are available at a 100-pin I/O
connector. Six are configurable as inputs and three are configurable as outputs.
Interrupts can be generated by up to seven ADC sources on both boards, and by up to four DAC sources on the
PCI-DAS6014.
Each board contains an 82C54 counter chip, which consists of three 16-bit counters. Clock, gate, and output
signals from two of the three counters are available on the 100-pin I/O connector. The third counter is used
internally.
Software features
For information on the features of InstaCal and the other software included with your PCI-DAS6013 and PCI-
DAS6014, refer to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available
in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.
Check www.mccdaq.com/download.htm for the latest software version.

Unpacking the PCI-DAS6013 and PCI-DAS6014
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DAS6013 and PCI-DAS6014 from its packaging, ground yourself using a
wrist strap or by simply touching the computer chassis or other grounded object to eliminate any stored static
charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately by
phone, fax, or e-mail:
Phone: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [e-mail]
Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-
Quick-Start.pdf.
Installing the hardware
The PCI-DAS6013 and PCI-DAS6014 boards are completely plug-and-play. There are no switches or jumpers
to set on the board. Configuration is controlled by your system's BIOS. To install your board, follow the steps
below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installing
the software.
1. Turn your computer off, open it up, and insert your board into an available PCI slot.
2. Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (such as Windows 2000 or Windows
XP), a dialog box pops up as the system loads indicating that new hardware has been detected. If the
information file for this board is not already loaded onto your PC, you will be prompted for the disk
containing this file. The MCC DAQ software contains this file. If required, insert the Measurement
Computing Data Acquisition Software CD and click OK.
3. To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the Quick Start Guide that came with your board for information on how to initially set up and
load InstaCal.
Allow your computer to warm up for at least 15 minutes before acquiring data with these boards. The high
speed components used on these boards generate heat and it takes this amount of time for a board to reach
steady state if it has been powered off for a significant amount of time.

PCI-DAS6013 and PCI-DAS6014 User's Guide Installing the PCI-DAS6013 and PCI-DAS6014
11
Configuring the hardware
All hardware configuration options on the PCI-DAS6013 and PCI-DAS6014 are software controlled. You can
select some of the configuration options using InstaCal, such as digital channel configuration (input or output).
Once selected, any program that uses the Universal Library initializes the hardware according to these
selections.
Following is an overview of the available hardware configuration options for this board. There is additional
general information regarding analog signal connection and configuration in the Guide to Signal Connections
(available on our web site at www.mccdaq.com/signals/signals.pdf).
Differential input mode
When all channels are configured for differential input mode, eight analog input channels are available. In this
mode, the input signal is measured with respect to the low input. The input signal is delivered through three
wires:
The wire carrying the signal to be measured connects to CH# IN HI.
The wire carrying the reference signal connects to CH# IN LO.
The third wire is connected to LLGND.
Differential input mode is the preferred configuration for applications in noisy environments, or when the signal
source is referenced to a potential other than PC ground.
Single-ended input mode
When all channels are configured for single-ended input mode, 16 analog input channels are available. In this
mode, the input signal is referenced to the board’s signal ground (LLGND). The input signal is delivered
through two wires:
The wire carrying the signal to be measured connects to CH# IN HI.
The other wire is connected to LLGND.
Non-referenced single-ended input mode
This mode is a compromise between differential and single-ended modes. It offers some of the advantages of
each mode. With non-referenced single-ended mode, you can still get noise rejection, but not the limited
number of channels resulting from a fully differential configuration. A possible downside is that the external
reference input must be the same for every channel. It is equivalent to configuring the inputs for differential
mode, tying all of the low inputs together, and using that node as the reference input.
When configured for non-referenced single-ended input mode, 16 analog input channels are available. In this
mode, each input signal is referenced to a common reference signal (AISENSE), and not to the board’s ground.
The input signal is delivered through three wires:
The wire carrying the signal to measure connects to CH# IN HI.
The wire carrying the reference signal connects to AISENSE.
The third wire is connected to LLGND.
This mode is useful when the application calls for differential input mode, but the limitation on channel count
prevents it.

Functional Details
Basic architecture
Figure 3 on page 19 shows a simplified block diagram of the PCI-DAS6013 and PCI-DAS6014. These boards
provide all of the functional elements shown in the figure.
The System Timing and Control (STC) is the logical center for all DAQ, DIO, and DAC (if applicable)
operations. It communicates over two major busses: a local bus and a memory bus.
The local bus carries digital I/O data and software commands from the PCI Bus Master. There are two Direct
Memory Access (DMA) channels provided for data transfers to the PC.
Primarily, the memory bus carries A/D and D/A (PCI-DAS6014 only) related data and commands. There are
three buffer memories provided on the memory bus:
The queue buffer (8K configuration memory) stores programmed channel numbers, gains, and offsets.
The ADC buffer (8K FIFO [First In, First Out]) temporarily stores scanned and converted analog inputs.
The DAC 16K buffer stores data to be output as analog waveforms (this buffer function only applies to the
PCI-DAS6014).
Auxiliary input & output interface
Each board's 100-pin I/O connector provides six software-selectable inputs, and three software-selectable
outputs. The signals are user-configurable clocks, triggers and gates.
Refer to the "DAQ signal timing" section on page 20 for more explanation of these signals and their timing
requirements.
The following table lists all of the possible and the default signals you use on the nine pins. D/A signals pertain
only to the PCI-DAS6014.
