=== Radio Interface ===

  * In the 2 RF Node configuration (ie only RF A and RF B are populated), you should only use the '''2RF bitstream''' in the [wiki:WARPLab/Downloads download].
  * In the 4 RF Node configuration (ie all RF interfaces are populated), you should only use the '''4RF bitstream''' in the [wiki:WARPLab/Downloads download]. 


=== Dip Switches ===

  * In WARPLab 7.1 and later, the dip switch value of 0xF (ie all switches set to '1'), is reserved for [wiki:WARPLab/Reference/NodesConfig dynamic node configuration].


=== Debug Header ===

''Updated for WARPLab 7.5'''

The [wiki:HardwareUsersGuides/WARPv3/DebugHeader debug header] is configured by default to map to the following pins:

'''NOTE:''' The Debug Header is defined in the system.ucf and the connections are defined in the system.mhs

  * The Trigger output and Trigger input pins above are used with the [wiki:WARPLab/Reference/TriggerManager Trigger Manager]


=== Clock Configuration ===

''Updated for WARPLab 7.5'''

The WARPLab reference design does not require any external clock connections. By default the reference design will use the oscillators on the WARP v3 board for all system and RF clocking.

The reference design does support both sourcing and sinking external clocks for synchronization of multiple nodes. The WARP v3 kit must be equipped with a [wiki:HardwareUsersGuides/CM-MMCX CM-MMCX Clock Module] to source/sink clocks. The role of each node is configured via the 2-position SIP switch on the CM-MMCX, according to the figure below.

  * Detailed information on the WARP v3 Clocking configuration can be found [wiki:HardwareUsersGuides/WARPv3/Clocking here].
  * To adjust the [wiki:HardwareUsersGuides/CM-MMCX CM-MMCX Clock Module] functionality, please use the following SIP switch settings:

=== Ethernet ===

  * By default, only Ethernet connection A (Eth A) is used.
