2.4.5 JR6, MUX GPIO22_24 Select
2.4.6 JP7, CANA Termination Resistor Select
2-22
Jumper JR6 is a surface mount jumper located on the bottom side of the board. To
use a configuration a zero ohm resistor should be used for shorting. This jumper is
used to route the signal GPIO22 or GPIO24 to connector P8, pin 33 (MUX GPIO22).
In configuration A GPIO22 is selected. When configuration B is used GPIO24 is
selected. These configurations are shown below.
The layout of this jumper is shown in the figure below.
Jumper JP7 is used to select the termination resistor on the CANA interface. When
installed a termination resistor is placed between pins 2 and 7 of the connector P7.
This jumper is installed at the factory. The positions are shown in the table below.
The layout of this jumper is shown in the figure below.
