Host Command Reference
Input Assembly (0x64)
This connection point is used to monitor the drive’s behavior. The 32 bytes of data sent by the drive are as
follows:
The data transmitted by the drive is sent in Little Endian format, so it will likely require rearranging before
use.
IP addresses said to be stored in “Internet Format” are simply encoded into hexadecimal notation and
rearranged into Little Endian format. Each octet has a value from 0-255, and can be represented by a single byte.
Standard IP address: 192.168.0.40
Convert to Hexadecimal: 192 = 0xC0
168 = 0xA8
0 = 0x00
40 = 0x28
Rearrange into Little Endian Format: C0 A8 00 28 -> 28 00 A8 C0
Converted IP address: 192.168.0.40 -> 0x2800A8C0
Note that all numbers are sent in Little Endian format, so the process for converting is the same for each
piece of data.
