AUX PORT SECURITY

This allows the Administrator to set a password for the AUX port to DISABLE

unauthorized AUX Port communications. The purpose is to prevent unauthorized users

from accessing the AUX port unless the password is supplied to re-ENABLE the port.

In the dialog, the current state is shown. The Administrator would select DISABLE

and supply a numeric password, and press the SET button. The supplied numeric

password should be remembered since it is required to ENABLE the AUX port while

communicating on the AUX port.

Once the AUX port is disabled, no communications are accepted over the AUX

port unless ENABLE PORT option is chosen in 1 of 2 ways.

• If communicating over the HOST PORT

o the ENABLE PORT command will enable AUX port communications and a

password is NOT required. This allows the unit to be reset over the HOST port

if the AUX password is forgotten. VeriAdmin allows this since the network is

considered secure.

• If communicating over the AUX PORT

o The ENABLE PORT command will enable AUX port communications ONLY if

the correct password is supplied. All other commands will return an error

indicated a ‘locked port’ until the port is enabled properly

Bioscrypt recommends that the AUX port be disabled and password

protected

When an Administrator needs to communicate with the device using the AUX Port,

the procedure would be:

• connect to the AUX port,

• use VeriAdmin to bring up the BII_UNIT PARAMETER SETTINGS dialog

• choose ENABLE PORT, supply the correct password, and press SET

All communications would then be allowed. Once all data is gathered, the Administrator

would then disable the AUX port by:

• use VeriAdmin to bring up the BII_UNIT PARAMETER SETTINGS dialog

• choose DISABLE PORT, supply a new password, and press SET

This would once again protect the AUX port from unauthorized use.
