Installing the PCIe-DAS1602/16
UnpackingAs with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device 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.
Contact us immediately if any components are missing or damaged.

Installing the software
Refer to the MCC DAQ Quick Start for instructions on installing the software on the MCC DAQ CD. Refer tothe device product page on the Measurement Computing website for information about the included andoptional software supported by the PCIe-DAS1602/16.
Install the software before you install your device
The driver needed to run the PCIe-DAS1602/16 is installed with the software. Therefore, you need to install thesoftware package you plan to use before you install the hardware.

Configuring the hardware
If you are using the PCIe-DAS1602/16 with its default settings, the board is completely plug-and-play. You canskip these configuration sections and refer to Installing the hardware.
If you are not using the PCIe-DAS1602/16 default settings, you will set one or more switches and jumpers
mounted on it before installing it into your computer. The factory-configured default settings are listed below.
The location of each switch and jumper are shown in Figure 2.

PCIe-DAS1602/16 User's Guide

Installing the PCIe-DAS1602/16

Before installing the PCIe-DAS1602/16 in the computer, make sure that the board is configured with thesettings that you want. Review the following information to change the default configuration of a jumper orswitch on the PCIe-DAS1602/16 board.
Board switches are covered by analog input shield
To access the channel mode switch (S1) and the A/D range select switch (S2), remove the metal analog input
shield that covers them. This shield is secured to the board with two screws.

Channel mode (S1 switch)
Use the S1 switch to set the channel mode configuration. Configure the PCIe-DAS1602/16 analog inputs for
either 8 DIFF channels or 16 SE channels.


Use SE input mode if you have more than eight analog inputs to sample.
Use DIFF input mode to allow for up to 10 V of common mode rejection. This mode provides better
noise immunity.

The S1 switch is factory-configured for 8 DIFF inputs, as shown in Figure 3. To configure for 16 SE channels,
set this switch to 16.

Figure 3. 16/8 channel select switch (S1) default setting (8)A/D converter range (S2 switch)
Use the S2switch to set the A/D converter range. This switch controls all A/D channels.
Switch S2 is factory-configured for bipolar. To configure for unipolar, set this switch to UNI.

Figure 4. A/D range select switch (S2)

Trigger edge (P8 jumper)
Use the P8 jumper to set the A/D pacer clock trigger edge. This jumper selects the edge that initiates the A/D
conversion when using the internal pacer clock.
Jumper P8 is factory-configured for rising edge.
When using the falling edge to start the conversion, the A/D may be falsely triggered by glitches in the 8254
pacer clock initialization. If the PCIe-DAS1602/16 is replacing an older series MCC board, using the risingedge to start the conversion may lead to timing differences.
For compatibility with MCC software and third-party packages, leave jumper P8 in the default rising edge
position.
Figure 5 and Figure 6 show the edge selection options for jumper P8.

Installing the PCIe-DAS1602/16

D/A converter (DAC) output range (P5, P6, and P7 jumpers)
Use the P7 jumpers to set the PCIe-DAS1602/16 onboard precision voltage reference and select the output
ranges of the DACs. Both DACs are factory-configured for a range of –5 V to +5 V (Figure 7.)
Two 12-bit multiplying DACs (DAC0 and DAC1) provide analog output. These DACs accept an input
reference voltage, and provide 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 (FS). For example, in unipolar mode, the supplied reference of 5 V provides a+5 V output (actually 4.9988 V) when the value in the output register is 4095 (FS 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 V to 5 V, 0 V to 10 V, ±5 V, ±10 V.
Other ranges between 0 V and 10 V are available when you provide a precision voltage reference at pin
10 (DAC0 REF IN) or pin 26 (DAC1 REF IN) of the main connector.

Figure 7. DAC0 and DAC1 range jumpers (P7)

Figure 8. DAC0 (P5) and DAC1 (P6) unipolar/bipolar jumpers

Simultaneous sample and hold (SSH) trigger
When the DAC1 reference is supplied onboard, pin 26 on the 37-pin connector is unused (Figure 11). You canenable this pin as a SSH trigger for use with the CIO-SSH16 board. To enable SSH, place the jumper between
the two pins labeled SSH in Figure 7.

Clock select (P2 jumper)
Use the P2 jumper to configure the frequency of the square wave used as a clock by the A/D pacer circuitry.
This pacer circuitry controls the sample timing of the A/D.
The clock select jumper is factory-configured for 1 MHz, as shown in Figure 9. You can set the clock source to
10 MHz if needed for the sample rates you plan to use.

Figure 9. Clock select (P2)Internal pacer output is also available at pin 20
The internal pacer output driving the A/D converter is also available at pin 20 (CTR 3 Output) on the main I/O
connector (see Figure 11 on page 11).

Installing the PCIe-DAS1602/16

Pull-up/down configuration (P3 jumpers)
Use the P3 jumpers to set the digital bits for pull-up (+5 V) or pull down (0 V) when the PCIe-DAS1602/16 is
powered on and reset. Ports A, B, CH, and CL are factory configured for pull-up.
These jumpers establish either a high (pull-up) or low (pull-down) logic level at each of the eight DIO lines on
ports A and B, and at each of the four DIO lines on ports CL and CH. The default pull-up configuration for all
ports is shown in Figure 10.

Install the software before you install your device
The driver needed to run the PCIe-DAS1602/16 is installed when you install the software. Therefore, you needto install the software before you install the hardware.
The PCIe-DAS1602/16 is susceptible to radiated emissions
The PCIe-DAS1602/16 is susceptible to radiated emissions from other devices in the chassis such as video
adapters or other PCI/PCIe devices in adjacent PCI/PCIe slots. This can result in AI input noise levels that areout of specification and is noted in the product electrical specification.
After you configure the board switches and jumpers (if any), install the PCIe-DAS1602/16 into your computer.
To install your board, follow the steps below:
1.

Power off and unplug the computer, and remove the cover to expose the expansion slots.

2.

Touch any metal part of the computer to discharge static electricity. Static electricity can damage the board.

3.

Insert the PCIe-DAS1602/16 into an unused x1 PCIe expansion slot.
The PCIe-DAS1602/16 is designed to install into an x1 slot. However, you can also install the board into anunused x4, x8, or x16 PCIe slot.

Caution! Make sure that you install the board into a PCIe slot. Installing the PCIe-DAS1602/16 into a
non-PCIe slot can damage both the board and the computer’s motherboard.
4.

Close your computer and turn it on.
A dialog box opens as the system loads, indicating that new hardware has been detected. The information
file for this board should have already been loaded onto your PC when you installed the software CD
supplied with your board, and should be detected automatically by Windows. If you have not installed thissoftware, cancel the dialog, install the software, and restart your computer.

5.

Run InstaCal to test your installation and to configure the board. Refer to the Quick Start Guide that camewith your board for information on how to initially set up InstaCal.

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.

Calibrating
Required equipment
To calibrate the PCIe-DAS1602/16, a precision (or non-precision) voltage source, a 5½ digit digital voltmeterand a few pieces of wire are required. Use a jeweler’s screwdriver to adjust the trim pots. An extender card is
not required to calibrate the board.

Field calibration
The PCIe-DAS1602/16 is shipped fully calibrated from the factory, and supports field calibration. For normal
environments, you should calibrate your PCIe-DAS1602/16 every six months to a year using InstaCal.
Calibrating with InstaCal takes less than 20 minutes.
You calibrate the A/D converters by applying a known voltage to an analog input channel and adjusting trim
pots for offset and gain. Three trim pots 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 PCIe-DAS1602/16 for the range you intend to use it in. When the range is changed, slightvariation in zero and full scale may result. These variations can be measured and removed in software if
necessary.
If frequent variations in temperature or humidity are common, recalibrate at least every three months. Refer tothe Quick Start Guide that shipped with your board for information about InstaCal.

Factory calibration
The Measurement Computing Manufacturing Test department performs the initial factory calibration. Contact
Measurement Computing for details about how to return your device and have it calibrated to the factory
specifications.

Each PCIe-DAS1602/16 is tested at the factory to assure the overall error of the board 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 caseerror is realized only in the unlikely event that each of the component errors is at their maximum level, andcauses error in the same direction.

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 caseerror is realized only in the unlikely event that each of the component errors is at their maximum level, andcauses error in the same direction.

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 is at theirmaximum level, and causing error in the same direction.
