RS-232 Port: The digital signal output RS-232 port (not shown in
Figure 3-2) is offered as a cost added option on the Model 3190. It is a
standard RS-232 serial communications port used to connect the
analyzer to a modem or other digital device. Only the output mode is
implemented in this instrument. The data is concentration information in
serial digital form.
The RS-232 protocol allows some flexibility in implementation in
the choice of values for certain parameters. Table 3-1 lists the RS-232
values required by the 3190 implementation.
