1. Phase Camera hardware Nothing really new, only summarising status
3 electronics boxes (dig. processing) ready
ADC characterisation ongoing (need few days more)
Then shipping to EGO site
Prototype in EE-room will be replaced (main difference is mechanics)
2 PDs ready
DC gain adapted
Not tested, laser setup at Nikhef not yet operational
Swap currently installed PD of PC1
Electrical splitter box ready
Will be shipped together with other boxes
Replaces prototype in EE-room
Cabling (electrical and fibres) for PC2, PC3 are at EGO site
Installation to be done in collaboration with Flavio
Also 2 coaxial cables between EE-rooms and other rooms needed.

2. Software Not all channels showed up data in dataDisplay
We have 22 ‘channels’ with power and phase info
11 demodulated PD frequencies, and 11 electrical reference frequencies
Power and phase of a channel is transmitted as one word
The power of the 11 ref. frequencies always showed zero, phase was non-zero
The power info in the raw data packets on the TOLM network were not zero
PC digital boards send out information -> display problem
For long time I thought to be due to the Dictionary
But at Nikhef, it works..
And now it (suddenly?) also works in Virgo, nothing changed in our code, maybe there was an update of dataDisplay?
I will check regularly whether it remains OK

4. Next steps
Next thing to get going for PC2/PC3 is the control of the mirrors via standard Virgo DAC channels
For PC1 use we an external generator
At the moment we do not yet have a DAQ-box at Nikhef
Hence can’t test it
