IrDA Downloading Cable
The instrument communicates with a computer via an on-board infrared 
communication port that complies with IrDA protocol standards.
NOTE: If your computer has a built-in infrared port, you do not need an 
adapter cable to download data.
If your computer does not have an infrared port, you will need to install an 
IrDA/USB adapter cable on your computer to use the GX-2012 Data 
Logger Management Program with your instrument. The IrDA/USB cable is 
available from RKI Instruments, Inc. See the Spare Parts List at the end of 
this manual for the RKI part number. This cable can also be found in many 
electronic supply stores and computer stores.
Some versions of Windows
®
 already have several infrared device drivers 
loaded in Windows

 and will automatically recognize a cable during the 
installation process and guide you in installing the drivers. Other versions 
of Windows

 will require you to load device drivers provided by the 
manufacturer of the cable during the installation process. RKI makes no 
warranty for the operation or compatibility of the drivers with any particular 
device.
Installing an IrDA Adapter Cable
After installing the GX-2012 Data Logger Management Program, connect 
the IrDA/USB cable to your computer and follow the manufacturer’s 
instructions for installing the cable on your computer. Make sure the cable 
is compatible with your Windows

 operating system.
If you do not have instructions from the cable manufacturer for installing 
your cable, see your Windows documentation. In general, you must go to 
the Control Panel and use the Add Hardware Wizard to install the cable 
drivers.
