Basic Configurations provide many combinations of the operating modes
and options listed below. See the Hardware Information section of this
manual for complete descriptions.
? RS-422/485 output drivers enable option: The SSP-200/300’s ports may be
configured for either full duplex or half duplex operation with this option.
The default setting is the RS-422/485 ports are configured for full duplex
operation with the RS-422/485 output drivers always enabled. In half duplex
mode, the RS-422/485 transmitter may be enabled and disabled via the RTS
(request to send) or DTR (data terminal ready) signals, or set to enable only
when data is being transmitted (auto-toggle). Both RTS and DTR are
controlled through the Modem Control Register of the 16750.
When the Use Automatic Settings check box is enabled Windows 95/98/ME
will attempt to configure the SSP-200/300 in the order listed in the Basic
Configurations table.
