Thanks for the information, I'll share these findings with Guido (support from CAEN).</div>

I would think that this issues was with the mainframe/CPU of .136 crate but since you moved 19671 card (card with reported issues) from .136 into slot 2 of .135 and only appeared the PVs for the .135 mainframe then I could think that the cards are the problem.</div>

I did not find any firmware file to download from CAEN website to upgrade the A1515BTG cards, this might be something to request to CAEN, if any newer is available.</div>

Here's a quick run down of what I noticed moving the HV cards around between the crates.</div>

There are 2 crates: caen-cnu-sbs (129.57.37.135) and caen-gem-c2 (129.57.37.136) I'll just refer to them by the last octet of the IP from now on.</div>

.135 (HiVoCS = 1.4.0 / HV Control = 1.3.2) has 5 modules installed four A1515BTGHP in slots 0, 1, 3, 4 and a single A1515BTG in slot 5 (s/n 27135)</div>

With these modules installed .135 shows PVs for the mainframe and all the cards while .136 only shows PVs for the mainframe, but neither card.</div>

When moving card 27135 from .135 to .136 into slot 5 and removing the cards from slot 2 and 4 (so only one card is installed) and power cycling the crate .136 now shows PVs for the mainframe and the card.</div>

I then removed this card and only installed 19671 in slot 4, this also showed PVs for the mainframe + card.</div>

Next having only 27077 installed slot 2 showed PVs for the mainframe + card.</div>

Since it appears at this point the issue is having more than one A1515BTG installed in a crate I moved 19671 from .136 into slot 2 of .135, once I did this now the only PVs that show up are the mainframe, i.e. no card PVs appear.</div>

I will note that all the A1515BTGHP cards have firmware 1.01 while all the A1515BTG cards have 1.00</div>

Hopefully that will help CAEN narrow down their troubleshooting some. Let me know if there's any questions.</div>
