Response
Note (1) If the service data is two bytes or four bytes (for example, word data or error clear codes), specify
the right byte first in the command format.
Example: Specify the word data 1234 hex in this sequence: 34 hex
→
12 hex.
Specify the double word data 12345678 hex in this sequence: 78 hex
→
56 hex
→
34 hex
→
12 hex.
These are the command formats.

+3 : 0095 hex Class ID 0095 hex
+4 : 0001 hex Instance ID 0001 hex
