3.2.1NetPorty II internal buffers:

To avoid lost data (CAN is faster than the communication channels to the PC) the transfer-objects are buffered in the NetPorty II. The biggest buffer is between CAN reception and the communication channel to the PC (448kByte). If you have many traffic on the CAN-bus and the buffer is full it takes a time of several minutes to transfer the data to the PC. You can control this with the 2nd NetPorty II LED that blinks faster while the data transfer.
