The IPS is the latest in a long line of systems that use the same basic command sequence. So if you can't get an IPS manual you can step back a generation and for all the basic programming the command manual for that will be adequate. In this case use the IVS manual which is commonly available. However from your posts I am wondering if you have ever done any programming?

Do you know how to get into CAT mode and do you know the password for the system?
