PCIM-DAS1602/16 Additional documentation In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf).
PCIM-DAS1602/16 User's Guide ! Installing the PCIM-DAS1602/16 Signal termination and conditioning accessories MCC provides signal termination and signal conditioning products for use with the PCIM-DAS1602/16. Refer to the "Field wiring, signal termination and signal conditioning" section for a complete list of compatible accessory products. Unpacking the board As with any electronic device, you should take care while handling to avoid damage from static electricity.
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.
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 Figure 2-3 is configured for unipolar. Figure 2-3.
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).

Chapter 3 Programming and Developing Applications After following the installation instructions in Chapter 2, your board should now be installed and ready for use. Although the board is part of the larger DAS family, in general there may be no correspondence among registers for different boards. Software written at the register level for other DAS models will not function correctly with your board.
Chapter 4 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.
