Command Specifications

This parameter page specifies transfer of the “Page code” list of the parameter page supported by the IDD in the SEND DIAGNOSTIC command and the RECEIVE DIAGNOSTIC RESULTS command to the INIT. Figure 3.19 shows the format of this parameter page. The page code list supported by the IDD is transferred to the INIT by the RECEIVE DIAGNOSTIC RESULTS command which is issued following the SEND DIAGNOSTIC command that specifies this parameter page (shown in Section 3.4.2 (1) )

b.Logical/physical address conversion

This parameter page specifies conversion of the address information expressed in either the “Logical Block Address,” “Physical Sector Address” or “Byte Distance from the Index” format to another expression format. Figure 3.20 shows this parameter page format. The INIT can specify the address information that should be converted in this parameter page of the SEND DIAGNOSTIC command, and can read the conversion results by the RECEIVE DIAGNOSTIC RESULTS command (see Section 3.4.2 (2)).
