5_Telium System Application (TSA) Menu
The Telium System Application (TSA) menu allows the user to verify the presence of encryption keys and serial numbers. The TSA
menu is accessed from the Functions main menu. Three menu options enable the user to verify that the encryption keys are present
(Key Check Value, Master Session, and DUKPT) and provide details on the keys which are loaded. Refer to the below figure for an
illustration of the TSA menu.
Please refer to the following sections for terminal serial number and encryption validation:
Terminal Serial Number
Encryption Validation
5_1 Terminal Serial Number
5_1_1 Hardware Part Number
The hardware part number is the device serial number. Only the last 8 characters of the hardware part number (40000808 for the
following example image) are displayed on the device screen when selecting the [Terminal Serial #] option.
