2.1.4 Jumpers
The phyBOARD-Regor comes with one removable jumper (JP) and two solder jumpers (J).
The removable jumper JP3 allows for optional termination of the CAN-interface by the user.
With jumpers J5 and J6, the interface at the Card Edge Connector X7 can be chosen to be a
RS485 (UART1) or a CAN (CAN0) interface.
By default, JP3 is set to terminate the CAN interface. J5 and J6 are set to connect the
RS485 interface to the card edge connector X7.
Due to the small footprint of the solder jumpers (J), PHYTEC does not
recommend manual jumper modifications. This might also render the
warranty invalid. Because of this, only the removable jumper is described
in this section. Contact the PHYTEC sales team if you need jumper
configurations different from the default configuration.
Figure 5
shows the location of the removable jumper JP3. The fixed jumpers J5 and J6 are
placed on the bottom of the PCB. The function of the jumpers on the phyBOARD-Regor are
described in
Table 5
. More detailed information can be found in the appropriate section.
