Caution:
When using the DB-9 plug P2A as CAN interface, and the CAN
transceiver on the Carrier Board with galvanic separation, the
following jumper settings are not functional and could damage the
module:
Jumper Setting Description
JP31 2 + 3 Pin 2 of DB-9 plug P2A connected with RD1 of the
phyCORE-LPC2292/94
JP32 2 + 3 Pin 7 of DB-9 plug P2A connected with TD1 of the
phyCORE-LPC2292/94
1 + 2 Input at opto-coupler U4 on the Carrier Board is
connected to SCLK0 of the phyCORE-LPC2292/94
2 + 3 Input at opto-coupler U4 on the Carrier Board is
connected to A22 of the phyCORE-LPC2292/94
JP11
open Input at opto-coupler U4 on the Carrier Board
not connected
1 + 2 Output at opto-coupler U5 on the Carrier Board is
connected to MISO0 of the phyCORE-LPC2292/94
2 + 3 Output at opto-coupler U5 on the Carrier Board is
connected to A21 of the phyCORE-LPC2292/94
JP12
open Output at opto-coupler U5 on the Carrier Board
not connected
JP13 2 + 3 Supply voltage for CAN transceiver and opto-coupler
derived from local supply circuitry on the
phyCORE Carrier Board HD200
JP18 closed CAN transceiver and opto-coupler on the Carrier
Board connected with local GND potential
JP29 open No power supply via CAN bus
JP39 see Table 60 Incorrect CAN bus supply voltage reduction for CAN
circuitry
