Parameter Object
(Class ID 0F
H
)
The Parameter Object provides the interface to the XM-122 configuration
data. There are 47 Parameter Object instances implemented in the XM-122
module.
Instances 1-4 and 7-37 are implemented to provide an alternate method of
setting the configuration parameters with EPATH or ENGUNIT data types.
And Parameter Object instances 46 and 47 provide an alternate method of
setting the Produced Connection Size and Produced Connection Path
attributes for the Poll Connection because these attributes can be difficult to
get/set directly through the Connection Object.
Parameter Object instances 5 and 6 are for setting the starting order for the
Sum Harmonics measurements. And Parameter Object instances 38-45
determine whether to use a standard spectrum or gSE spectrum when
calculating band values.
