Biasing and Termination Jumpers (B0–B8 and C0–C8)
If COM0 or COM1 is configured for RS-485 communication, use Jumpers B0 through B8 for biasing and
terminating COM0, and jumpers C0 through C8 for biasing and terminating COM1. RS-485/422 lines
require proper termination and biasing for reliable operation. Communication lines require termination at
the physical beginning and end of an RS-485/422 link, and require biasing at one location anywhere in the
link. Table 3-2 describes each jumper’s function and Figure 3-4 shows
how jumper settings affect the RS-485/422 electrical schematic.
