USB to Serial Adapter
USB to Serial Adapter
Agilent strongly recommends to connect the 2100 Bioanalyzer instrument
directly to a serial port on the PC. However, if the PC does not offer this
option, connect the 2100 Bioanalyzer instrument to USB drive utilizing an
Agilent USB-Serial Adapter cable. This cable includes a controller component,
which requires the installation of a driver allowing the USB to emulate a serial
port.
For Expert software B.02.08 and greater
It is recommended to use the new Agilent USB-Serial Adapter cable (Part
number 5188-8031, black cable) for 2100 Expert Software version B.02.08 and
greater.
If the PC is connected to the internet, the correct driver will install
automatically when the USB-Serial Adapter cable is plugged into the USB port
of your PC.
For off-line systems, please install the driver from the Agilent 2100 Expert
Software CD by clicking on the executable file found in
SupportDriver/88-8031CDM20824.exe. If a CD is not available, download the
driver.
Install the driver (http://www.genomics.agilent.com/article.jsp?pageId=2353 )
prior to connecting the adapter and the 2100 Bioanalyzer instrument and
proceed as described below.
• Close the 2100 Expert Software.
• Execute the installation program of the driver and follow the instructions.
Reboot the operating system.
• Physically connect the 2100 Bioanalyzer instrument and the laptop by using
the USB-Serial Adapter cable and the standard Serial RS-232 cable.
