Note: To guarantee the safety of your data, it is very important to change the factory set
PIN (page 65). Change the smart card PIN periodically. It is recommended to use different
PINs for different smart cards. The numerical order must be kept confidentially.
After successful PIN entry, the cryptographic keys are transferred to the encryption
module and the “STATUS“-LED illuminates red. The DIGITTRADE HS256 S3 will be
identified by the operating system as a removable device and the lighting of the keypad
goes out. The “ACTIVE“-LED flashes during the data transfer.
The access is enabled now. The smart card must remain in the DIGITTRADE HS256 S3
whilst in operation. If the smart card will be removed from the slot, the storage device
is locked (lock-out mode).
If necessary this function can be deactivated, so that the smart card can be removed after
the authentication and you still will have access to the HS256 S3. The “STATUS”-LED
illuminates green after successful PIN entry. Please find more information in chapter 5.2.
Upon removal of the smart card, the “STATUS” LED turns off and the “ACTIVE” LED is
green.
If a wrong PIN was entered, the red “ERROR“-LED flashes and it sounds an acoustic
signal. Press the “ESC“ button to restart the PIN entry.
Note: After the PIN was entered eight times incorrectly, the smart card will be irrevoca-
bly locked and cannot be used anymore. The cryptographic keys on the smart card are
irreversible deleted in the process.
Note: In the activated status the HS256 S3 must not be unattended to prevent unauthor-
ized access. Please note, if you are leaving your workplace and if you are not using the
DIGITTRADE HS256 S3, it should be locked correctly. All data transfers must be complet-
ed and the HS256 S3 must be seperated from the USB connector. If the lock-out mode is
activated it is sufficient to remove the smart card from the associated slot.
For security reasons it is recommended to hide traces upon entry that could allow
conclusions about the use of PIN numbers. Possible methods can be:
1. Frequent cleaning of the keypad, so no fingerprints are visible.
2. Frequent tapping of all buttons, so fingerprints are spread evenly.
3. Using special stylus pens that do not leave marks on the surface of the keypad,
such as the DIGITTRADE stylus pen.
