Pro II: Multi-IO Modules
Pro II-MIO-4 Rev. E
ADwin
The module has an input voltage range of ±10V and a software selectable gain
of 1, 2, 4 or 8. The adjustment of gain and offset is done by software (see chap-
ter 6 "Calibration").
The module includes a sequential control, which can read measurement val-
ues from several or all input channels sequentially.
The module can monitor each input channel, if an upper or a lower limit–you
can set the limits for each input channel separately–has been exceeded.

Analog Outputs
The module Pro II-MIO-4 Rev. E has 4 analog outputs each with a 16 bit DAC.
Each output has a fixed 1st order low-pass filters (fc = 10MHz) to suppress
noise.
The output voltage range of the DACs is set to ±10V bipolar and can’t be
changed. Offset and gain are adjusted by software (see chapter 6 "Calibra-
tion").
The outputs are available on a 37-pin D-Sub female connector; for pin assign-
ment see fig. 17.

Digital Inputs / Outputs
The digital input/output module Pro II-MIO-4 Rev. E provides 8 programmable
digital input and output channels with TTL levels. The channels can be confi-
gured as blocks of 4 as inputs or outputs by
ADbasic
instructions. The chan-
nels are configured as inputs after power up.
Via the trigger input EVENT a signal can trigger a process, which will be pro-
cessed at once and completely (see
ADbasic
manual).
