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 white block next to the 3-pin header. Putting the shunt on the opposite 2 pins disables the option, and
is simply a place to store the shunt.
