4-Wire Mode
To configure the 485DSS for RS-485 or 422 four-wire mode,
place the jumper in the 4W position. Refer to Figure 4 for
connecting information and Figure 2 for the jumper location. In this
position on a 4-wire network the Host and the RS-232 device can
communicate in full duplex. CAUTION: Data loss may occur if the
Host sends 485DSS commands while the host is receiving data
from the network!
