AMS Trex Security
Upgrade Studio lets you manage secure access to Trex units. You can configure a Trex unit
to have Local, Enterprise, or no security scheme.
Initial setup
An Upgrade Studio user can initially set the security of a Trex unit to either Local or
Enterprise security. Subsequently, only this user can change the security scheme of the
Trex unit. Other users may change the security scheme once the first user changes the
security to None.
Local security
Local security only allows user accounts created on the Trex unit to access it.
When local security is selected, an Administrator user must be created on the Trex unit.
This Administrator user can create or delete other users on the Trex unit. The
Administrator user is only deleted when the security of the Trex unit is set to None using
Upgrade Studio.
Enterprise security
Enterprise security requires Windows Active Domain credentials to access a Trex unit.
When enterprise security is selected, a Windows domain name, wireless network service
set identifier (SSID), username, and password is required the first time the Trex unit is
used. A wireless network with WPA2-Enterprise security is required.

Near-field communication (NFC) card access
You can use an NFC card, a technology used in badge entry systems or payment cards, to
control access to a Trex unit using the Security Management settings. You must first
enable a security scheme on the Trex unit before pairing it with an NFC card. Pairing the
Trex unit with an NFC card requires you to enter a PIN. Only one NFC card and PIN
assignment is supported for a Trex unit user.
The Trex unit supports NXP NTAG21x series NFC cards. The NTAG21x series are 2nd
generation NFC chips by NXP. The NTAG21x series NFC cards have a unique 7-byte UID
(Serial Number) that Trex units use when pairing a card to a user.
