b. Serial interface Setup
The submenu "Serial interface Setup" is used to set the
parameters for data transfer between the analyzer and
external devices. The choices in this menu depend on
the configuration of the analyzer. The full specification
of the serial interface is described in its own manual.
In the System SIO Module menu (Figure 3-16) select
"Serial interface setup..."
