Default hardware configuration
The PCIM-DAS1602/16 board has several switches and jumpers mounted on it that you must set before
installing into your computer if you are not using the default settings. The factory-configured default settings
are listed in Table 2-1. The locations of each switch and jumper are shown in Figure 2-1.
PCIM-DAS1602/16 User's Guide Installing the PCIM-DAS1602/16
Figure 2-1. PCIM-DAS1602/16 switch and jumper locations
Before installing the PCIM-DAS1602/16 in the computer, verify that the board is configured with the settings
that you want. Review the following information to change the default configuration of a jumper or switch on
the PCIM-DAS1602/16 board.
Board switches are covered by a metal nameplate
To access the Channel Select switch and the A/D Range Select switch, remove the metal nameplate that covers
them. This plate is secured to the board with two screws.
Channel Select switch
Set the channel mode configuration with switch S1. The analog inputs of the PCIM-DAS1602/16 can be
configured as eight differential channels or 16 single-ended channels. Use the single-ended input mode if you
have more than eight analog inputs to sample. Using the differential input mode allows up to 10 volts of
common mode (ground loop) rejection and will provide better noise immunity.
This switch is factory-configured for eight differential inputs. The Channel Select switch shown in is
set to the "8" position. To configure for 16 channels, set this switch to 16.
PCIM-DAS1602/16 User's Guide Installing the PCIM-DAS1602/16
A/D Range Select switch
The A/D converter range is set by switch S2. This switch controls all A/D channels.
Although you cannot run some channels bipolar and some unipolar, you can measure a unipolar input in the
bipolar mode (for example, you can monitor a 0 to 5V input with a channel set to the ±5 V range). This switch
is factory-configured for bipolar. The A/D Range Select switch shown in is configured for unipolar. Figure 2-3
Figure 2-3. A/D Range Select switch
Trigger Edge Select jumper
The original Keithley MetraByte DAS-1600 was designed such that A/D conversion initiates on the falling edge
of the convert signal. Neither the original DAS-16, nor any of the other DAS-16 derivative converts on the
falling edge of the signal. In fact, we are not aware of any A/D board that uses the falling edge to initiate the
A/D conversion.
When using the falling edge to start the conversion, the A/D may be falsely triggered by 8254 pacer clock
initialization glitching. False triggering is easy to avoid, but may occur in the DAS-1600. Since initiating
conversions on the falling edge is undesirable, but initiating on the rising edge may lead to timing differences if
the PCIM-DAS1602/16 board is used as a replacement for an older DAS16 series board, the PCIMDAS1602/16 is equipped with a jumper that you can use to select the edge that initiates the A/D conversion.
The Trigger Edge Select mode is configured by jumper
P8. This jumper is factory-configured for rising edge.

DAC0 and DAC1 Range Select jumper (D/A Converter Reference)
The PCIM-DAS1602/16 has an on-board precision voltage reference at jumper P7 that you can use to select the
output ranges of the digital to analog converters. Both of the board's D/A outputs are factory-configured with a
range of −5 to +5 volts (.) Figure 2-5
Analog output is provided by two 12-bit multiplying D/A converters (DAC1 and DAC). This type of converter
accepts an input reference voltage, and provides an output voltage which is both inverse to the reference voltage
and proportional to the digital value in the output register. The proportion is controlled by the D/A output code
(0 to 4095). Each bit represents 1/4096 of full scale. For example, in unipolar mode, the supplied reference of
−5 V provides a +5V output (actually 4.9988 V) when the value in the output register is 4095 (full scale at 12
bits of resolution). It provides a value of 2.5 V when the value in the output register is 2048.
A precision −5 V and −10 V reference provides onboard D/A ranges of 0 to 5 V, 0 to 10 V, ±5 V, ±10 V. Other
ranges between 0V and 10V are available when you provide a precision voltage reference at pin 10 (D/A0) or
pin 26 (D/A1) of the board's main connector.

Installing the PCIM-DAS1602/16
After you configure the board's switches and jumpers, install the PCIM-DAS1602/16 into your computer. 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 any available PCI slot.
2.
Close your computer and turn it on.
3.
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.
4.
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.
Board configuration with InstaCal
If you change the board configuration with InstaCal, you may have to also physically change the setting of a
corresponding switch or jumper on the board. Refer to Default hardware configuration on page 2-2 for specific
jumper and switch information.
Allow your computer to warm up for at least 15 minutes before acquiring data. The high speed components
used on the board 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.

Register-level programming
You should use the Universal Library or one of the packaged application programs mentioned above to control
your board. Only experienced programmers should try register-level programming. If you need to program at
the register level in your application, refer to the Register Map for the PCIM-DAS1602/16 (available at
The PCIM-DAS1602/16 is shipped fully calibrated from the factory. For normal environments, you should
calibrate your PCIM-DAS1602/16 board using InstaCal's calibration procedures every six months–to-a year. If
frequent variations in temperature or humidity are common, recalibrate at least every three months. It requires
less than 20 minutes to calibrate the board using InstaCal.
The InstaCal calibration procedure is explained in the DAQ Software Quick Start that was shipped with your
board.
Calibrating the A/D & D/A converters
InstaCal provides step-by-step on-screen instructions to guide you in calibrating your board. You calibrate the
board's A/D converters by applying a known voltage to an analog input channel and adjusting trim pots for
offset and gain. There are three trim pots that require adjustment to calibrate the analog input section of the
board. There are also three pots associated with each of the analog output channels.
Calibrate the PCIM-DAS1602/16 for the range you intend to use it in. When the range is changed, slight
variation in Zero and Full Scale may result. These variations can be measured and removed in software if
necessary.
Required equipment
To calibrate the PCIM-DAS1602/16, you need a precision voltage source, or a non precision source and a 5½
digit digital voltmeter and a few pieces of wire. Use a jeweler’s screwdriver to adjust the trim pots. An extender
card is not required to calibrate the board.
Integral Linearity Error ±0.5 LSB typ , ±3.0 LSB max
Differential Linearity Error ±0.5 LSB typ, ±2.0 LSB max
Each PCIM-DAS1602/16 is tested at the factory to assure the board’s overall error does not exceed ±5 LSB.
Total board error is a combination of gain, offset, differential linearity and integral linearity error. The
theoretical absolute accuracy of the board may be calculated by summing these component errors. Worst case
error is realized only in the unlikely event that each of the component errors are at their maximum level, and
causing error in the same direction.

Analog Input Zero drift Overall Analog Input drift
Absolute error change per °C Temperature change is a combination of the gain and offset drift of many
components. The theoretical worst case error of the board may be calculated by summing these component
errors. Worst case error is realized only in the unlikely event that each of the component errors are at their
maximum level, and causing error in the same direction.
Noise performance
The following table summarizes the worst case noise performance for the PCIM-DAS1602/16. Noise
distribution is determined by gathering 50000 samples with inputs tied to ground at the PCIM-DAS1602/16
main connector. Data is for both Single-Ended and Differential modes of operation.

Independent (D/A0 pin 10 and D/A1 pin 26)
System dependent. Using the Universal Library programmed output function
(cbAOut()) in a loop, in Visual Basic, a typical update rate of 400 Khz can be
expected on a 300 MHz Pentium II based PC.
Differential linearity error ±0.5 LSB typ, ±1 LSB max
Total board error is a combination of gain, offset, differential linearity and integral linearity error. The
theoretical absolute accuracy of the board may be calculated by summing these component errors. Worst case
error is realized only in the unlikely event that each of the component errors are at their maximum level, and
causing error in the same direction.
Analog output drift
Analog output full-scale gain drift ±0.22 LSB/°C max
Analog output zero drift ±0.22 LSB/°C max
Overall analog output drift ±0.44 LSB/°C max
Absolute error change per °C temperature change is a combination of the gain and offset drift of many
components. The theoretical worst case error of the board may be calculated by summing these component
errors. Worst case error is realized only in the unlikely event that each of the component errors are at their
maximum level, and causing error in the same direction.
