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

PCIM-DAS1602/16 User's Guide Installing the PCIM-DAS1602/16

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.

Turn your computer off, open it up, and insert your board into any available PCI slot.

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.

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.

Calibrating the PCIM-DAS1602/16

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.

Accuracy

Typical Accuracy ±2.3 LSB

Absolute Accuracy ±5.0 LSB

Accuracy Components

PGA Linearity Error ±1.3 LSB typ , ±10.0 LSB max

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.
