2938	Hi When a Can node transmits a stuff bit, say bit 1, and its receiver monitors the bit as 0 then what is the error condition: Is it a Bit error or a Stuff...	van do vdo42@...	Sep 3, 2003 8:36 am
2939	Hi Van, It's a stuff error. A bit error occurs when the CAN receiver sees the opposite polarity of a fixed field bit. For example, the CRC delimiter is...	John Dammeyer johnd@...	Sep 3, 2003 9:21 am

2948	Hi, No. That's not really true. If you assigned one ID value to very node you have 2^29 possible IDs. The reality is that without repeaters, you can't have...	John Dammeyer johnd@...	Sep 4, 2003 11:39 pm

2952	Hi Luc, not directly. But what you can do is to put a device or tool with 2 CAN controllers into the line between the ECUs as a gateway. You could transfer...	"Klüser, Jürg... Juergen.Klueser@...	Sep 5, 2003 3:11 pm
2953	Luc, What do you mean by "overwrite"? If you mean, is it possible to send another message at the same time as the ECU sends it's message and cause the bus to...	Allen Pothoof apothoof@...	Sep 5, 2003 3:14 pm
