Installing the PCIM-DAS1602/16

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 ofcommon 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 Figure 3 isset to the "8" position. To configure for 16 channels, set this switch to 16.

Figure 3. 8/16 Channel Select switch

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 Figure 4 is configured for unipolar.

Figure 4. 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 edgeof the convert signal. Neither the original DAS-16, nor any of the other DAS-16 derivative converts on thefalling edge of the signal. In fact, we are not aware of any A/D board that uses the falling edge to initiate theA/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.

PCIM-DAS1602/16 User's Guide

Installing the PCIM-DAS1602/16

The Trigger Edge Select mode is configured by jumper P8. This jumper is factory-configured for rising edge.
Figure 5 shows the edge selection options.

Figure 5. Trigger Edge Select jumper

For compatibility with all third party packages, with all DAS-16 software, and with PCIM-DAS1602/16
software, leave this jumper in the default rising edge position.

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 theoutput ranges of the digital to analog converters. Both of the board's D/A outputs are factory-configured with arange of –5 to +5 volts (Figure 6.)
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.

Simultaneous sample and hold (SSH) trigger
When the DAC1 reference is supplied on-board, pin 26 of the 37-pin connector is unused (Figure 8). You canenable this pin as a SSH (simultaneous sample & hold) trigger for use with the CIO-SSH16 board. To configure
this, place the jumper between the two pins labeled SH, as shown in Figure 6.

Clock Select jumper
Jumper P2 configures 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.
You can configure the frequency for 10 MHz or 1 MHz. The Clock Select jumper is factory-configured for
1 MHz, as shown in Figure 7.

Figure 7. Clock Select jumper

Configure this jumper for 10 MHz, unless you have reason to do otherwise.
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 OUT) on the board
analog connector (see Figure 8 on page 12).

Installing the PCIM-DAS1602/16

Installing the hardware
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 installingthe 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.
If you are using an operating system with support for plug-and-play, a dialog box notifies you that new
hardware has been detected. If the information file for this board is not already loaded onto your PC, youwill be prompted for the disk containing this file. The MCC DAQ software contains this file. If required,insert the MCC DAQ 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 andload InstaCal.

Board configuration with InstaCal
If you change the board configuration with InstaCal, you may have to also physically change the setting of acorresponding switch or jumper on the board. Refer to Default hardware configuration on page 7 for specificjumper 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.

Signal connections

Chapter 3

Calibrating the PCIM-DAS1602/16
The PCIM-DAS1602/16 is shipped fully calibrated from the factory. For normal environments, you shouldcalibrate your PCIM-DAS1602/16 board using InstaCal every six months to a year. If frequent variations intemperature or humidity are common, recalibrate at least every three months. Calibration using InstaCal
requires less than 20 minutes.

Calibrating the A/D & D/A converters
InstaCal provides step-by-step on-screen instructions to guide you in calibrating your board. You calibrate theboard's A/D converters by applying a known voltage to an analog input channel and adjusting trim pots foroffset and gain. There are three trim pots that require adjustment to calibrate the analog input section of theboard. 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, slightvariation 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.

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 are at their maximum level, andcausing 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 are at theirmaximum level, and causing error in the same direction.
