Authentication checking (enhanced models only)
In addition to the anti-subversion scans that occur continuously, enhanced
versions(AVSC1102-XXandAVSC1104-XX)oftheAdderViewSecurealso
provide a trusted mechanism whereby you can confirm their authenticity.
At manufacture, qualifying AdderView Secure units have a unique identity code
conguredwithintheircircuitry.Onrequest,Addercanprovideyouwithan
Authentication Certificate when you provide the following information:
• The8-digitUnitID, and
• The16-digitRequestCode.
Both of these codes are listed on the AdderView Secure unit.
Oncethevalidityofyourrequesthasbeen
confirmed, you will be sent an Authentication
Certificate containing the following:
• Conrmationofthe8-digitUnitID,
• Aunique16-digitQueryCode, and
• AKeyMap which shows a series of
indications that the AdderView Secure
unit must give in response to particular
key presses that you can enter.
