Chapter 2 Installation and Configuration
PCI-1200 User Manual 2-2 © National Instruments Corporation
Board Configuration
The PCI-1200 is completely software configurable. The PCI-1200 is fully
compliant with the PCI Local Bus Specification, Revision 2.0. Therefore,
all board resources are automatically allocated by the system. For the
PCI-1200, this allocation includes the base memory address and interrupt
level. You do not need to perform any configuration steps after the system
powers up.
Analog I/O Configuration
Upon power-up or after a software reset, the PCI-1200 is set to the
following configuration:
• Referenced single-ended input mode
• ±5 V analog input range (bipolar)
• ±5 V analog output range (bipolar)
Table 2-1 lists all the available analog I/O configurations for the PCI-1200
and shows the configuration in reset condition.
Both the analog input and analog output circuitries are software
configurable. Refer to your software documentation for more information
on changing these settings.
Table 2-1.
