3.0 CONFIGURABLE ANALOG OUTPUT OVERVIEW
There are three different methods to extract concentration data from the
analyzer: internal data acquisition system (DAS), hyperlink, or strip chart.
DAS
The user can set up an internal DAS configuration either through the user
display or using TAPI’s windows based software called APICOM. The
analyzer stores data internally, which is available later for download
through the RS-232 or Ethernet port.
Hyperlink
The user sends text based commands to retrieve data through the RS-232
port.
Strip Chart
The user interfaces a strip chart recorder and/or data-logger to the four
analyzer analog output channels of the rear panel Analog Out connector
(Figure 3-1). Table 3-1 presents the default configurations of the analog
outputs, and Table 3-2 shows the Pin-outs for these four channels.
