For the B7_PD2 the threshold was set to 10mA for a trial and we forgot to restored it to 50mA, is was done 2018-09-20-07h19m26.

Note that a reload Config is not enough to restore the threshold, today one need to reconfigure the mezzanine

For the B5_PD{1,2} and the B1_PD1 DC and Audio signal, there was some trouble with the Service mezzanine SN22 (SDB2_MezzPD1) while it was running with the firmware v3r1.

Restoring the previous firmware v3r0 allows to have the SDB2_MezzPD1 running correctly .We left the SDB2_MezzPD1 with this firmware (v3r0)
