Figure 10 . Back panel of PPM100. Computer interface ports on the back panel of the
PPM100 include: (1) HOST RS232, (2) GPIB, (3) USB, and (4) 10 BASET Ethernet
port (for embedded web server)
Tip! Computer interfacing is only required for: (1) Computer monitor/control of the PPM100 and vacuum
system, (2) Remote access to data-logs and history lists, (3) calibration data uploads, and (4) firmware
upgrades (for controller and web server).
The PPM100 itself is a standalone instrument - there is no need to connect the controller to an external
computer to access its full performance and functionality. All instrument functions and parameters are
manually accessible and easily modified through its menu-driven user interface.
Internet Access
An Embedded Web Server (EWS) connects the PPM100 to the World Wide Web. The EWS is a TCP/IP
compatible web server that resides inside the PPM100 box, continuously gathering data from the
instrument. When connected to an ethernet network with an Internet gateway, the EWS can deliver
PPM100 data to a user anywhere on the world wide web using a standard browser. Users can monitor
their vacuum system gas composition from anywhere in the world. E-mail notification can notify a client
list of potential or real system problems.
