register that is read using the QE command is updated by the RIO every 25ms. See the QE, WE and SE
commands in the RIO command reference for more information.

Part number ordering example:
RIO-47122-QUAD
-PWM
Using the DY, PM and FQ commands, digital outputs 14 and 15 can be configured as PWM outputs with a
frequency range of 10-20,000 Hz. This is only available on firmware Revs D and above. By default the
maximum frequency output will be limited by the bandwidth of the digital outputs. With the -PWM option
the opto-isolated outputs are bypassed and buffered outputs are supplied for DO 14:15.
