SYSTEM PARAMETERS
The HD9155 Production Afterburner hardware allows the user to change the default behaviour of various
functions by the use of parameters. Note that the System Parameters will only affect the behaviour of the
HD9155 when the front panel CONFIG switch is set to USER. These parameters are grouped according
to classes and can easily be changed using the 9150 Configware™ software. Within each class a
parameter number identifies parameters. Each parameter has a value with the default value for each
parameter being zero. Parameter class 0 and 15 apply to the HD9155 and will be described in this
chapter. Table 5-1 and Table 5-2 show the currently defined parameters for each class with a brief
description of what each parameter does. The parameter numbers shown in the tables below are decimal
numbers. The following sections describe the operation of each parameter in detail.
