6.2.5.1 Jumper selections on NXL basic board
The user is able to customise the functions of the frequency converter to better suit his needs by selecting
certain positions for the jumpers on the NXL board. The positions of the jumpers determine the signal type
of analogue input (terminal #2) and whether the termination resistor RS485 is used or not.
The following figures present the jumper selections of NXL frequency converters:
