16.3.7 First CAN Interface at Plug P2A
Plug P2A is the lower plug of the double DB-9 connector at P2. P2A
is connected to the first CAN interface (CAN1) of the
phyCORE-LPC2292/94 via jumpers. Depending on the configuration
of the CAN transceivers and their power supply, the following three
configurations are possible:
1. CAN transceiver populating the phyCORE-LPC2292/94 is
populated and the CAN signals from the module extend directly to
plug P2A.
Jumper Setting Description
JP31 2 + 3 Pin 2 of the DB-9 plug P2A is connected to CAN_L1
from on-board transceiver on the phyCORE module
JP32 2 + 3 Pin 7 of the DB-9 plug P2A is connected to CAN_H1
from on-board transceiver on the phyCORE module
JP11 open Input at opto-coupler U4 on the phyCORE
Carrier Board HD200 open
JP12 open Output at opto-coupler U5 on the phyCORE Carrier
Board HD200 open
JP13 open No supply voltage to CAN transceiver and opto-coupler
on the phyCORE Carrier Board HD200
JP18 open No GND potential at CAN transceiver and opto-coupler
on the phyCORE Carrier Board HD200
JP29 open No power supply via CAN bus
JP39 open No power supply via CAN bus
