About the NI PCI-6110/6111
Thank you for buying an NI PCI-6110/6111. The NI PCI-6110/6111 is a
Plug and Play, multifunction analog, digital, and timing I/O device for PCI
bus computers. The NI PCI-6110/6111 features a 12-bit A/D converter
(ADC) per channel with four or two simultaneously sampling analog
inputs, 16-bit D/A converters (DACs) with voltage outputs, eight lines of
TTL-compatible DIO, and two 24-bit counter/timers for TIO. Because the
NI PCI-6110/6111 has no DIP switches, jumpers, or potentiometers, it is
easily software-configured and calibrated.
The NI PCI-6110/6111 is a completely switchless and jumperless DAQ
device for the PCI bus. This feature is made possible by the NI MITE bus
interface chip that connects the device to the PCI I/O bus. The MITE
implements the PCI Local Bus Specification so that the interrupts and base
memory addresses are all software configured.
The NI PCI-6110/6111 uses the National Instruments DAQ-STC system
timing controller for time-related functions. The DAQ-STC consists
of three timing groups that control AI, AO, and general-purpose
counter/timer functions. These groups include a total of seven 24-bit and
three 16-bit counters and a maximum timing resolution of 50 ns. The
DAQ-STC makes possible such applications as buffered pulse generation,
equivalent time sampling, and seamless changes to the sampling rate.
The NI PCI-6110/6111 uses the Real-Time System Integration (RTSI) bus
to easily synchronize several measurement functions to a common trigger
or timing event. The RTSI bus consists of the RTSI bus interface and a
ribbon cable to route timing and trigger signals between several functions
on as many as five DAQ devices in the computer.
