5.3.2.1 Assignment of different USB device numbers
If several PC system bus adapters of type 2177 are connected to the PC different USB device numbers
have to be assigned to them to distinguish between the adapters.
Please proceed as follows:
1. Make sure that the system bus adapter to which a new USB device number is to be assigned is
the only PC system bus adapter of type 2177 connected to the PC.
2. Enter the corresponding USB device number in the input field Device number.
– The device number will be immediately transmitted to the system bus adapter. For
initialization, the system bus adapter has, however, to be disconnected for a short time from
the USB port.
– Note: Under Windows 2000/XP, a USB device may only be removed from the USB port after
logging off over the Tray icon ”Safely remove hardware” in the task bar. For the system bus
adapter select the entry ”PCAN-USB”.
3. Remove the system bus adapter for a short time from the USB port. When the adapter is
plugged in again, it will be reinitialized and the new device address will become effective.
4. Repeat the first three steps for all PC system bus adapters of type 2177 which are to be used
on the PC.
