Handshaking selection and Interface selection

The table below shows the relation between handshaking selection and interface selection.

Table 6. Handshaking and interface

Note

•In RS-422A mode, selecting DTR handshaking outputs the DTR flag through the DTR pin (No. 20); selecting X-on/X-off handshaking, fixes the value of the DTR

•The signal is always in a fixed, flag reset state. Signal polarity can be inverted with DIP switch 3-4.
