The drive and robotic sections may not be detected by the host system, or may not be properly associated for use with DiscJuggler. Properly configuring each component to allow DiscJuggler to correctly identify each section and establish a logical link between each drive/robotic pair is very important.

The following are some important rules to follow before you install DiscJuggler with a disc autoloader device.

• Make sure you use good quality serial cables; usually serial autoloaders require a "null-modem" straight through cable. Use a serial gender-changer, if necessary, to properly connect the device to your system.
   

• Make sure the COM port to which you are connecting the autoloader is not already in use. Many systems come with an internal modem that is likely using the same COM port that you are trying to use for the autoloader.
   

• Be certain that the COM port that you select for the autoloader is not using an IRQ that is normally used by another serial port. Many PCs have a default setup where COM1 and COM3 (and COM2 and COM4) share an IRQ; you should choose a COM port that is not inadvertently already sharing an IRQ with another active serial port.

Once DiscJuggler has been installed, the autoloader device needs to have its drives properly associated before DiscJuggler is put to use.

• Start the Drive Assigner by using the Drive Assigner shortcut on the Desktop or in the Start menu (default location: Start » Programs » Padus DiscJuggler » Drive Assigner).
   

• Once all devices have been detected, associate the drives physically located in an autoloader with that autoloader.
   

• Press the Update button followed by the OK button to finalize the process of associating drives with the autoloader.
