3.1.5 Serial Interface Switch (RS232C)
This switch specifies the connections for the ML670100 serial port pins PIO5.6 and
PIO5.7: to the RS232C driver IC (ENA) or to the corresponding user interface
connector pins (DIS).
Figure 3.9.
Serial Interface Switch (RS232C)
Setting this switch to its ENA position connects the ML670100 serial port pins PIO5.6
and PIO5.7 to the RS232C driver IC; the DIS position, to the corresponding user
interface connector pins.
Figure 3.10 shows the related circuitry.
