Quick Installation
Zone
Description
A
SA TA A channel – Connect to motherboard SAT A host using standard SAT A 22-Pin cable.
B
SATA B channel – Connect to SATA disk drive via direct insertion.
C
Socket for key fob insert. The AES secret key code i s written to the on-board EEPROM.
Or, it can be done with the external key fob. If your board comes with an external key fob,
it will not have an on-board EEPROM.
1. Connect the A connector (SATA channel A as illustrated in Figure 1) to your motherboard
or controller SATA host via a standard SATA 22-Pin cable.
2. Connect the B connector (SATA channel B as illustrated in Figure 1) to your SATA hard
disk via direct insertion.
3. The dongle board is default at Crypto Mode, which means the key code is affixed to the
dongle board as a form of key fob. If key fob is not applied, the MX dongle boa rd acts as a
pure ByPass mode, which read/write data blocks in clear text. If the key fob is applied, the
MX dongle board enters into Crypto mode for regular cryptographic operations.
4. For development purpose, the AES key is affixed to the key fob. To alter AES key and later
on the development stage to deliver the AES key, remove the key fob.
5. Power up your System.
6. Partition and Format this new X-Wall MX controlled disk drive with key fob ON and load
OS and/or other applications software just like what you had performed with a regula r
unencrypted disk drive. The X-Wall MX automatically and transparently encrypts whe n you
write and decrypts when you read.
