Processing Unit Operation

8-2
Theory of Operation: Overview
The Solar 9500 has three main components: the processing unit, displays
(with touchscreens), and acquisition devices. The processing unit
receives digital encoded information from the acquisition devices. Smart
acquisition devices (e.g. the TRAM, SAM, etc...) send post-processed
waveform and parameter data to the CPU. While non-intelligent devices
(e.g. BP and Temp modules) send (via the Tram-Rac) filtered and
digitized, but non-processed, data to the processing unit. The processing
unit further processes the waveform and parameter data, reformats for
the data, and then directs it for drawing on one or more displays or to one
or more printers. The data is also processed for alarm control, trending,
and sending to other network devices.
The Solar 9500 Processing Unit is an Intel Architecture platform. It is
based on a main processor board (or Motherboard), a Riser/Interface
board, a Riser I/O board, a power supply sub-assembly, and a hard drive.
Optional graphics boards are installed into the PCI bus sockets. The
Riser/Interface board is found at the bottom of the chassis. All boards
plug into the riser board directly or through a ribbon cable except for the
main-memory boards which plug into the Motherboard.
