When Where Who What
20130716 OAA   BcuNumber3 received from MPE
20130730 OAA MB Exchanged with BcuNumber1 in LgswRack2
20131119 OAA LB, MA Installed BCULogic v11.69
20140203 OAA MA BCU board HW modified for fastlink issue
20140204 OAA LB BCU Logic updated to 11.70
20140403 OAA MA, GOX, LB Removed from LgswRack2 and back in MicrogateSrl to fix the FLAO Input port
20140415 OAA MA, GOX, LB Back in OAA after fix the FLAO Input port. BCU logic updated to 11.71
20140415 OAA MA, GOX, LB Communication test using FLAO-ARGOS-SWITCH using BCU_11.71 and 6.08
20140415 OAA MA, GOX, LB implemented and tested reset to 0 FLAO slopes BCU_11.71 and 6.09
20140415 OAA MA, GOX, LB implemented and tested ADC enable/disable using DSP_8.46
20140417 OAA MB shipped to LBT
20140425 LBT GR,ML, GOX Installed in LgswRack1 for successful ASM communication test
20141103 LBT GOX Update of the BCU NIOS to BCUNios_5_09_0046 + use of two new ldr file (BCU 6_10, DSP_2_05)

20150525 LBT GR, LB Removed from LgswRack1. Ready to be shipped to MicrogateSrl for power supply upgrade
201608xx MIC MA Modification on the minicrate power supply to improve the long term stability of the output voltage. With the modification the voltage level on the boards is now very stable and, considering the adopted solution, we assure this stability over long time. (As from MA email of 7/9/2015)

20161020 LBT MB, JB Removed BCU board #00069 and installed BCU board #00048 taken from BcuNumber2
20161117 MPE JZ Shipped to MIC for repairing of BCU board and DSP
20170417 MIC MA, HG Shipped to MPE and LBT
20170919 LBT GR Stored in ArgosCabinet0
20200921 LBT GR Installed in SX LgswRack2. IP address still needs to be changed. Issues with EngPanel not working in ARGOS laptop
20200925 LBT GR Changed IP address to 192.168.32.140 using the LBTO AO laptop.
20201005 LBT GR Removed from SX LgswRack2. Installed in DX LgswRack1 (exchanged with BcuNumber2). IP address changed to 192.168.31.141 using VirtualBox.
20210622 LBT GR Sent to MicrogateSrl for repair.
20220301 LBT GR Received from MicrogateSrl.
20220305 LBT GR Taken to the observatory.
20220308 LBT GR

Installed in DX LgswRack1. IP address changed to 192.168.31.141 using EngPanel on VirtualBox from dx-lgsw (IP address had been changed while at Microgate).

MC comment:"

  • One DSP board of one of the High Voltage boards. There was probably an aging problem, most likely some soldering spot of the DSP was not very stable. We tried a re-working, which partially succeeded but was not stable, so we decided to replace the whole board
  • Some of the relais on the High Voltage board that disconnect the load

All other boards, including the ADC ones, were thoroughly checked and calibrated.

Known issues

20140403 OAA MA, GOX, LB FLAO Input port (#3) seems not working
20161016 LBT MB It shuts down after ~30-50 min of operation, voltage goes completely to 0, few power cycles are needed to revive it
20161020 LBT MB, JB New minicrate power supply seems to overheat the electronic that shuts down in less than 1 min if not cooled in the rack. Minicrate shuts down even if piezos are not connected and configured...
20200925 LBT GR Diagnostics does not work properly most of the time. And when it does, there is a single frame on the CCD and then frame rate stays at 0.0
