Unknown Device when Connecting Autosampler via USB
Issue
When trying to connect an ASX-560 via USB to the PC, the device shows up under "Other devices" in Device Manager instead of being assigned a COM port under the "Ports" menu
In December of 2022, Cetac implemented new Rev 3 boards in their Cetac ASX-560 and Cetac ASX-280 autosamplers. These new boards are not compatible with older versions of Windows prior to Windows 10 for the USB connections.
-The new board will still work with Windows 7 when communicating via a serial RS232 (9-pin) connection using port COM1, when available.
Environment
- ASX-560
- ASX-280
- Windows 10
Resolution
- Use serial connection. if available. on COM 1.
- If there is no available serial port on the computer, send customer an Extra Serial Port (PCI card) via P/N 2600256 for the customer's IT department to install
- Have customer use a USB to Serial port adapter
NOTE:
Serial Number Cut-offs*
Cetac started building with Rev 3 boards with these serial numbers.
ASX-280 - 102262A280
ASX-560 - 1022121A560
These five Thermo (ASX-560) SDX-99-0005s that went out with the Rev 2 boards that are out of sequence with the serial numbers above.
112202A560
112203A560
112204A560
112205A560
112206A560
* We’re going to get (may have already received) a final batch of several hundred Rev 2 boards, and these will be used for ASX-560, ASX-280 and XLR-860 systems until they’re all gone, which means that the serial number cutoff (above) should be considered that point at which Rev 3 boards started shipping, not the point onwards from which all boards will be Rev 3.
Note: Another way to identify if the Rev 3 or Rev 2 board is present in the autosampler is that the Rev 2 board has a big black central chip on the mainboard whereas the Rev 3 boards do not.
**Note: The serial number for the autosamplers are a date code formation (MMYY##ASX0) for month, year, build # and model number of the autosampler. So, ASX-560 (S/N 1022121A560) would be the 121st unit built in October 2022.
