Step Pulse Input Read Selection

The R208 RoHS version now has the option to change the way the R208 reads in the step

pulse train. By default, it understands one pulse when it reads the falling edge of the pulse.

To change this setting so that it reads one pulse when it sees a rising edge of the pulse,

simply turn power off, switch the dipswitch towards the “+” (positive) silkscreen marker,

then power back on.

Note: Old units read the pulse on the falling edge (-).
