Pulse Generation
The B1 can be instructed to output a specific number of pulses (with programmable period) at any
output position. Continuous square waves can also be generated.
Event Counting
Any or all input positions can function as event counters to return a count of external events. The
count ranges from 0 to 65,535. Each of the event counters can be individually read, stopped, and
cleared. Frequencies of up to 400 Hz with a minimum duty cycle of 50 percent can be counted.
Pulse Duration Timers
Any or all of the input positions can function as pulse duration timers. Either ON or OFF pulses can
be timed with a resolution of 10 milliseconds.
Analog Optomux
In addition to simple input and output, B2 Optomux units perform:
Analog Input Averaging
The B2 can be instructed to average the values of successive readings.
High/Low Limit Testing
Input ranges can be established for input positions, causing flags to be set when either high or low
limits are exceeded. These flags can be read and/or cleared by the host computer at any time.
Output Waveform Generation
Square waves, triangle waves, and ramps can be generated at any of the 16 module positions with
programmable rates.
High/Low Value Recording
The B2 can be instructed to remember the highest and lowest readings at input positions for recall
by the host computer.
Gain and Offset Calculation
The B2 can be instructed to calculate and set offsets and gain coefficients for input positions
allowing for easy calibration under software control.
