Product Identification

LXA TAC product label layout

Example for a LXA TAC product label

The LXA TAC is delivered with a product label containing an unique serial number, the product revision and the MAC addresses of the device.

An example for such a product label is shown to the right. The corresponding device has the serial number 00009.00014, indicating it is the 14th instance in product class 00009 (LXA TAC Assembly). A copy of the serial number is also included in the data-matrix code to allow semi-automatic identification of devices.

Revisions of the device

In addition to the serial number, every device is marked with a revision. For example the revision string lxatac-D01-R02-V01-C00 would decode to:

  • D01 - First device in the lxatac device class

  • R02 - Device revision two

  • V01 - Assembly variant one

  • C00 - No post-manufacturing hardware changes

The following revisions of the devices have been manufactured:

  • lxatac-D01-R01-V01-C00: LXA TAC Prototype (Gen 1) [development only]

  • lxatac-D01-R01-V01-C02: LXA TAC Prototype (Gen 1 with Gen 2 retrofit) [development only]

  • lxatac-D01-R02-V01-C01: LXA TAC Pre-Series devices (Gen2) [development only]

  • lxatac-D01-R02-V01-C02: LXA TAC Pre-Series with changes according to EMC testing (Gen 2 with Gen 3 retrofit) [early access]

  • lxatac-D01-R02-V01-C03: LXA TAC Pre-Series with changes according to EMC testing (Gen 2 with Gen 3 retrofit and improved USB host port performance) [early access]

  • lxatac-D01-R03-V01-C00: LXA TAC Series Production devices (Gen 3.0)

  • lxatac-D01-R03-V01-C01: LXA TAC Series Production devices (Gen 3.0 with improved USB host port performance)

  • lxatac-D01-R04-V01-C00: LXA TAC Series Production devices (Gen 3.1)

  • lxatac-D01-R04-V01-C01: LXA TAC Series Production devices (Gen 3.1 with improved USB host port performance)

MAC-Addresses

Each TAC is shipped with an allocation of 16 MAC addresses, some of which are not used by default but instead available to the user. The MAC: 18:74:e2:a0:00:f_ string on the example label indicates that MAC addresses 18:74:e2:a0:00:f0 to 18:74:e2:a0:00:ff are allocated to this LXA TAC.

Known Issues

This section lists releases with known issues and possible fixes for those.

  • lxatac-D01-R02-V01-C02 (Gen 2 with Gen 3 retrofit):

    • USB devices with high peak-current demand (like USB-WiFi) may not work as expected.

    • Solution: These devices can be updated to lxatac-D01-R02-V01-C03. Contact sales for more information.

  • lxatac-D01-R03-V01-C00 (Gen 3.0):

    • USB devices with high peak-current demand (like USB-WiFi) may not work as expected.

    • Solution: These devices can be updated to lxatac-D01-R03-V01-C01. Contact sales for more information.

  • lxatac-D01-R04-V01-C00 (Gen 3.1):

    • USB devices with inrush currents higher than specified by the USB specification (e.g. the LXA USB-Mux) can not be used.

    • Solution: These devices can be updated to lxatac-D01-R04-V01-C01. Contact sales for more information.
