The RS-485 line has 620 Ohm pull-up and pull-down resistors on lines A and B. The
biasing resistors ensure that, during idle periods the data lines are kept at a stable voltage
level and prevent false triggering of receiver input. These resistors can be enabled
installing jumpers J2 and J1 respectively.

A 120 Ohm termination resistor between A and B can be enabled installing jumper J3.
