Caution:
When using the DB-9 connector P2B as second CAN interface and the
CAN transceiver on the Carrier Board 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
on-board CAN transceiver on the
phyCORE-LPC2292/94
JP34 2 + 3 Pin 7 at P2B is connected with CAN_H2/TD2 from
the on-board CAN transceiver on 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 1 + 2 Supply voltage for CAN transceiver and opto-coupler
on the Carrier Board derived from external source
(CAN bus) via on-board voltage regulator
JP29 closed Supply voltage for on-board voltage regulator
from pin 9 of DB-9 connector P2A
JP39 see Table 60 CAN bus supply voltage reduction for CAN circuitry
