(D) Unsigned8

(E) Boolean

(F) Integer16

(G) Integer16

(H) Integer32

(I) Unsigned8

(M)

Octet String[6]

}

******

Note:

represents bits or bytes skipped for alignment purposes. When the structure is read,

this data is not transmitted; when the structure is written, this data is written to the value 0.

X represents data values.

Octet String[5] and Octet String[6] behave identically

. Both transfer 6 bytes on both read and

write.
