14.3.6 Second CAN Interface at Plug P2B
Plug P2B is the upper plug of the double DB-9 connector at P2. P2b
is connected to the second CAN interface (CAN1) of the
phyCORE-167CS via jumpers. This option is only available if the
phyCORE module is populated with the Infineon C167CS (order
option PCM-009-C1). Depending on the configuration of the CAN
transceivers and their power supply, the following three
configurations are possible:
1. CAN transceiver populating the phyCORE-167CS is enabled and
the CAN signals from the module extend directly to plug P2B.
Jumper Setting Description
JP33 2 + 4 Pin 2 of the DB-9 plug P2B is connected to CAN-L1
from on-board transceiver on the phyCORE module
JP34 2 + 3 Pin 7 of the DB-9 plug P2B is connected to CAN-H1
from on-board transceiver on the phyCORE module
JP14 open Input at opto-coupler U6 on the phyCORE
Development Board HD200 open
JP15 open Output at opto-coupler U7 on the phyCORE
Development Board HD200 open
JP13 open CAN transceiver and opto-coupler on the Development
Board disconnected from supply voltage
JP18 open No GND potential at CAN transceiver and opto-coupler
on the phyCORE Development Board HD200
JP29 open No power supply via CAN bus
