with the ARC program I have never had to do anything beyond download from Radio Reference. Are you sure about your response?
If the system is TRBO your scanner is unable to decode the signals. In fact no scanner currently on the market can decode these signals. What Anthony is referring to is a program you can use along with a discriminator tap to decode these signals. I do not know if the program plus tap will work with this system because I have never used it and am not that familiar with it.
Simply putting the frequencies in from the database does not work with this system because of the type of transmission. If you want more information on using a discriminator tap you can do a search of the forums for more information.
In short you will not be able to monitor Caterpillar.
