Parameter Object
(Class ID 0F

H

)

The Parameter Object provides the interface to the XM-123 configuration
data. There are 32 Parameter Object instances implemented in the XM-123
module.

Instances 1-28 are implemented to provide an alternate method of setting the
configuration parameters with EPATH or ENGUNIT data types. And
Parameter Object instances 31 and 32 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 29 and 30 are for determining which filter
measurement (tracking or bandpass) is performed by the module.
