Switch 4 determines whether or not the RS-232-C port of the 1785-KE
module can detect duplicate messages transmitted to it.

Switch 5 determines whether the RS-232-C port on the 1785-KE module
uses and recognizes the following handshaking signals.
data set ready (DSR)
request to send (RTS)
clear to send (CTS)
data carrier detect (DCD)
data terminal ready (DTR)

Important:
If you select half-duplex, the 1785-KE uses handshaking
signals even if switch 5 is set UP.
To set diagnostic commands, you use switch 6 on SW-1. Use the table
below to set switch 6.
