7.8 Multi­Output Board
The output for Stream #1 is obtained from the
Input/Output Panel (see Figure 2­5). The additional
five outputs are obtained from the lower left­hand side
of the analyzer. Table 7­14 gives the pin assignments
on the “D” connector for a multi­stream system: 

7.7     Relay Output Option
This port (see Figure 7­7) is a collection of contact
closures that can be used to identify either the
stream being displayed or the alarm that is activated
(multi­stream systems only). these are not “powered”
contacts.
