PC-DIO-24/PnP User Manual
PnP
PnP (Plug and Play) refers to a device that is fully compatible with the
industry standard Plug and Play ISA Specification. All bus-related
configuration is performed through software, freeing you from
manually configuring jumpers or switches to set the device base address
and interrupt level. PnP systems automatically arbitrate and assign
system resources to a PnP product.

resolution
the smallest signal increment that can be detected by a measurement
system. Resolution can be expressed in bits, in proportions, or in

part in 4,096 resolution, and 0.0244% of full scale.
