Configuring the DAQPad-MIO-16XE-50
This section describes how to configure the DAQPad-MIO-16XE-50.
Parallel Port
During configuration, you must know the parallel port I/O address and
interrupt channel. Common parallel port I/O addresses are 0x378, 0x278,
0x3BC, 0x280 and 0x290. The DAQPad-MIO-16XE-50 can use the
parallel port hardware interrupts for interrupt-driven data acquisition.
Interrupt levels 7 and 5 are commonly used for parallel ports. Refer to the
computer reference manual for details about interrupt selection and address
assignment. For configuration problems, refer to Appendix B,
Troubleshooting for Configuring Parallel Ports
.
Analog Input
The AI section of the DAQPad-MIO-16XE-50 is software configurable.
You can select different AI configurations through application software
designed to control the DAQPad-MIO-16XE-50. The following sections
describe in detail each of the AI categories.
Input Mode
The DAQPad-MIO-16XE-50 has three different input
modes—nonreferenced single-ended (NRSE) input mode, referenced
single-ended (RSE) input mode, and differential (DIFF) input mode. The
single-ended input configurations use up to 16 channels. The differential
input configuration uses up to eight channels. Input modes are programmed
on a per channel basis for multimode scanning. For example, you can
configure the circuitry to scan 12 channels—four differentially configured
channels and eight single-ended channels. Table 2-1 describes the three
input configurations.
