A.3 RS-485 Line Termination & Bias
Enable line termination only when this device is placed at the end of the network.
Termination should only be enabled at two points on the network, and these two
points must be specifically the end points.
Enable line bias when needed. Line bias should only be enabled at one point on the
network, and does not have to be the end point. Line bias holds the line in a known
neutral state when no devices are transmitting. Without bias, the transition from
offline to online by a transmitter can look like a false start bit and cause loss of
communication.
The line conditioning options are enabled when the respective shunt is moved to the
position indicated by the diagrams below.
