+SVEC-based FD x 2
+=================
+
+This is a WRTD :ref:`node` based on the `Simple VME FMC Carrier (SVEC)
+<https://www.ohwr.org/project/svec/wikis/home>`_ and the `FMC Fine Delay generator
+(FMC-FD) <https://www.ohwr.org/project/fmc-delay-1ns-8cha/wikis/home>`_.
+
+The basic principle of this :ref:`node` is simple: the :ref:`node`
+also receives WRTD :ref:`Messages <message>` which are then used to
+generate pulses at a predefined moment on one of the FMC-FD outputs.
+
+Architecture and performances are similar to :ref:`svec_ref_tdc_fd`.
+The node has 10 :ref:`Local Output Channels <local_channel>` are
+mapped to the five inputs of each FMC-FD.

+SVEC-based TDC x 2
+==================
+
+This is a WRTD :ref:`node` based on the `Simple VME FMC Carrier (SVEC)
+<https://www.ohwr.org/project/svec/wikis/home>`_ and the `FMC Time to Digital Converter (FMC-TDC)
+<https://www.ohwr.org/project/fmc-tdc-1ns-5cha-hw/wikis/home>`_.
+
+The basic principle of this :ref:`node` is simple: it takes in external pulses on its FMC-TDC
+inputs, timestamps them using WR time and converts them to WRTD :ref:`Messages <message>`, to be
+sent over the WR network.
+
+Architecture and performances are similar to :ref:`svec_ref_tdc_fd`.  The node has 10 :ref:`Local Input Channels <local_channel>` are mapped to the five inputs of each FMC-TDC.
