		DRVcan-S (SWC) can't send wakeup frames Q: I'm trying to send wakeup (high voltage) frames using CANalyzer (or CANoe) and a DRVcan-S. When I measure the voltage on the bus I can't see the 12 volts I'd expect. The CAN messages are sent, however, and I don't get any error indication from the CANalyzer. What's up?
		Solution Upgrade the drivers to the latest version available. There are two kinds of DRVcan-S's. They differ in CAN driver chip revisions and there is no visible difference. The newer type needs at least version 3.1.19.0 of vcndrvms.dll (and this DLL is shipped with the driver routines.) The older type works with version 3.0.9.0.
