Resolution
In some cases configuring Cetac for USB port use has solved timing error problems.
Two RS-232 serial I/O ports (COM1 and COM2)
The serial ports are located on the left side at the back of the Auto Sampler. The COM1 port is the communications interface between the ASX-520 and the analytical instrument’s host computer. The COM2 port connects the Auto Sampler to other external devices, such as an Auto Dilutor.
USB Option
TheASX-520 comes standard with a USB port. This port can be used to interface the ASX-520 with the host computer. Use the drivers Cetac supplied on a CD with the autosampler (USB Serial port), you will also need to set-up for COM 1 thru the computer Control Panel.
Changing the COM Port Number
With the release of V1.02.07, FTDI has introduced a properties sheet which allows the user to change the COM port number of a USB serial port.
From DeviceManager, select "View devices by type", then "Ports (COM & LPT)". Select the USB serial port and click Properties. Select the "Port Settings" tab, then click Advanced. Choose the required COM port number from the list and click OK.
If a modem is attached to the USB serial port when the port number is changed, it will continue to work under the new port number.
If a modem had been attached to the USB serial port but was not attached when the port number was changed, it will not work when re-attached under the new port number. In this case, the modem must be removed from the system and re-installed.
In general, if there are devices in the system which have been attached previously to the USB serial port, they may not work after the port number has been changed. If this is true, remove the device from the system and re-install it.
