Caution:
When using the DB-9 plug P2B as second 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
JP30 closed Pin 8 at P2B is connected with TxD1_ext
from the phyCORE-LPC2292/94
1 + 2 Pin 2 at P2B is connected with RxD1_ext
from the phyCORE-LPC2292/94
JP33
2 + 4 Pin 2 at P2B is connected with CAN_L2/RD2 from the
phyCORE-LPC2292/94
JP34 2 + 3 Pin 7 at P2B is connected with CAN_H2/TD2 from the
phyCORE-LPC2292/94
1 + 2 Input at opto-coupler U6 on the Carrier Board is
connected to P1.21 of the phyCORE-LPC2292/94
2 + 3 Input at opto-coupler U6 on the Carrier Board is
connected to A23 of the phyCORE-LPC2292/94
JP14
open Input at opto-coupler U6 on the Carrier Board
not connected
1 + 2 Output at opto-coupler U7 on the Carrier Board is
connected to P1.20 of the phyCORE-LPC2292/94
2 + 3 Output at opto-coupler U7 on the Carrier Board is
connected to A20 of the phyCORE-LPC2292/94
JP15
open Output at opto-coupler U7 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
