The DTH-v1 is the first prototype for the DAQ upgrade in 2025.

It is a ATCA card containing a DAQ part, a TCDS2 part and a ethernet switch.

The place of the the DTH is the hub slot of the ATCA crate. This first version hasn't the ethernet connectivity to the backplane. Another prototype has been developed  to debug the ethernet part of the DTH. The DTH-P2 will include the ethernet part to distribute the 1Gb on all ATCA slots.
