Figure 2-29.WSR-88D Principal User Processor (PUP).
Two 19" color/graphic monitors that are used to
display products in full or 1/4 screen mode.
A graphic tablet and "puck" that are the primary
input devices used to make product selections or request

A color/graphics printer that provides hard

A processor that computes or executes user
commands (such as zooming, roaming, displaying
maps or overlays, and implementing time-lapse loops of
products). It also lets you annotate (write, or draw on)
products to highlight features such as fronts. The
processor also executes special product requests and

components resemble a computer workstation.
A system console alphanumeric terminal that is
usually located in close proximity to the PUP work
space. It consists of a monochrome monitor and
keyboard. The system console controls the processor by
invoking hardware and software commands that affect
PUP functions. It also receives alphanumeric products
or messages that are not displayed on the graphic
