How does the PPM100 interface to
the SRS RGA?
A very important feature of the PPM100 controller is that it eliminates the requirement to connect the
SRS RGA to a host PC computer. The RGA is instead connected directly to the PPM100 controller
through its standard RGA-RS232 serial interface port and all data is displayed on the front panel of the
controller.
Warning! PPM100 is not compatible with third-party residual gas analyzers
A menu-driven user-interface allows the PPM100 operator to easily program all required RGA Setup
parameters from the controller’’s front panel- i.e. no RGA Windows software interface is required.
Note that the PPM100 is a standalone instrument - there is no need to connect the controller itself to an
external computer to access its full performance and functionality.
