E Boards

Thank you for buying a National Instruments PCI-6110E/6111E
board. Your 611X E board is a completely Plug and Play, multifunction
analog, digital, and timing I/O board for PCI bus computers. The
611XE board features a 12-bit ADC per channel with four or two
simultaneously sampling analog inputs, 16-bit DACs with voltage
outputs, eight lines of TTL-compatible digital I/O, and two 24-bit
counter/timers for timing I/O. Because the 611X E board has no DIP
switches, jumpers, or potentiometers, it is easily software-configured
and calibrated.
The 611X E board is a completely switchless and jumperless data
acquisition (DAQ) board for the PCI bus. This feature is made possible
by the National Instruments MITE bus interface chip that connects the
board 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 611X E board uses the National Instruments DAQ-STC system
timing controller for time-related functions. The DAQ-STC consists
of three timing groups that control analog input, analog output, 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 seamlessly
changing the sampling rate.
Often with DAQ boards, you cannot easily synchronize several
measurement functions to a common trigger or timing event. The
611XE board has the Real-Time System Integration (RTSI) bus to
solve this problem. The RTSI bus consists of our RTSI bus interface
