Chapter 2 Installation and Configuration Analog Output Polarity The PCI-1200 has two channels of analog output voltage at the I/O connector. You can configure each analog output channel for either unipolar or bipolar output. A unipolar configuration has a range of 0 to 10 V at the analog output. A bipolar configuration has a range of –5 to +5 V at the analog output. In addition, you can select the coding scheme for each D/A converter (DAC) as either two’s complement or straight binary. If
