Either RS-232 or USB may be used, but not both at once.
USB Cable Problems
Check the USB cable to ensure it is plugged into the port on the autosampler.
1
Check the host computer to ensure that the USB cable is connected to the
appropriate USB port.
2
Check that the USB cable is not damaged in any way.
3
Check the host computer to ensure that the USB drivers are installed for USB
operation of the autosampler.

functioning with the ICP-MS software, ensure that the software is
communicating correctly with the autosampler. To do so, verify proper
operation of all manual functions by completing the following steps:
Connect to the autosampler using a terminal emulation program (see
"Operating a CETAC Autosampler Using a Terminal Program" on page 69).
1
Enter some commands, such as HOME.
2
If the commands have no effect, and a USB connection is being used, check that
the autosampler is plugged into the same USB port as it was when the driver
software was configured. Unlike many consumer devices, each USB port used
as a "virtual" COM port must be individually configured.
If manual commands work, but the autosampler does not operate with the ICP-
MS software, carefully check that the ICP-MS software is configured to use the
3
COM port where the autosampler is plugged in.
If a USB connection is used, and if the manual commands work, but the ICP-MS
software fails to operate the autosampler, check that the same COM port
number is configured in the ICP-MS software and in the USB device driver.

An ASX-112FR Autosampler alignment malfunction may be caused by bumping
the Y-arm out of alignment during a sampling sequence. If the autosampler
begins missing target vials or the rinse station during a sampling sequence,
complete the following:
