If you need to change these settings, see the following sections. Otherwise, you can simply install the card. Note that you will need to disable your CPU card’s on-board COM ports, if any, or set them to alternate addresses/IRQs. PCL-841 Series User's Manual... - Page 10 Jumpers JPI and JP2 set the interrupts for Port I and Port 2, respec- tively. You can choose any IRQ from 3 to 15, except 8, 13 and 14. When you choose IRQs, make sure they are not used for other cards in the system.

The following example program, can84 I.lib, implements the sending and receiving of messages over the CAN controller. The program is written in C. #include "can841.h" /*Library function declaration*/ /*------------------------------------------------*/ /* CAN controller interrupt connection */ #define CAN1_IRQ 12 /* 0 means polling */ #define CAN2_IRQ 15 /* 0 means polling */ #define PORT1 0 #define PORT2 1... - Page 21 /* Send to CAN1 */ if(canReceiveMsg(PORT2, &rmsg2)==1) cprintf("PORT2 receive:ID=%3X RTR=%ld Length=%ld", rmsg2.id,rmsg2.rtr, rmsg2.dlen); for(i=0; i< rmsg2.dlen; i++) cprintf(" %2X",rmsg2.data[il); printf("\n"); if (kbLit()) getch(); break; /* Reset CAN controller. */ canReset(PORTl); canReset(PORT2); canExitHW(); clrscr(); PCL-841 Series User's Manual...

Page 24: Datamonitor Utility
Before you transmit a CAN object, you must configure the CAN controller by selecting the <Config> menu with the cursor keys and pressing <Enter>. The Configuration function determines the ports to be used and their communication parameters. The port configuration window is shown below. The parameters below need to be configured for each CAN controller: Address segment: The base address (address segment) of the PCL-... -

The monitored data for a selected port appears in the monitor screen (see area B in the diagram under Main Menu section.) If the CAN controller is configured correctly and the transmission has been successfully completed, every CAN object will be shown inorder of appearance. PCL-841 Series User's Manual... - Page 26 Status fields at the right of the screen display the status of the two ports: The status fields show information including the Mode (Normal or Reset), Acceptance Code, Acceptance Mask, BTR0, BTRI, Output Control Register, and Status Register.
