Levels Enable, RS232 or RS422
The switcher levels which will be controlled by the Serial Interface
are determined by the left-most switch. If the segment associated
with a level is ON, that level is controlled. The same switch
determines whether the Serial Interface will communicate with
the external controller in RS232 or RS422 standard. If the segment
associated with a standard is ON, that standard is selected. (Only
one may be used). The switch is illustrated below.
