3.2.2
RS485 Term
Close jumper in order to terminate the RS485 bus interface (120 Ohm resistor between RS485A and
RS485B).
3.3
DIP switches
The most important settings (motor run current, motor standby current, microstep resolution,
StallGuard functionality and operating mode) can be set by DIP switches. Please note that the settings
of the DIP switches are only read right after the module has been powered on. So it is necessary to
cycle power to make changes of the DIP switch settings take effect.
All parameters that can be set by the DIP switches can also be changed via RS485 commands (but the
initial power-on settings are always taken from the DIP switches).

3.3.1
Motor current settings
The motor run current can be set independently from the motor standby current. There are five DIP
switches altogether for setting the run current and three DIP switches for specifying the current
reduction during motor stops / standby. Please note that the possible current settings in mode 1 are
different from those in mode 0 and 2.
