etmx slow daq chassis |

All parts received and assembly near complete, small problem detected because the two DSub connectors are too close together for two cables to fit at the same time. Gautam and I will make some additional slot panels tomorrow using a waterjet cutter, so we can spread the breakout boards out and remedy this.
Fast binary channels need to be spliced into DSub connectors. Aaron is on this. All other, slow connections are already wired from before and have been tested for correct pins on the backplane DIN connectors.
The Acromag modules require only a positive supply voltage between +12 and +30 VDC and draw a maximum of 2.8W at that. This raises the question if we want this supply rail to be regulated or take the raw power from the Sorensens. Consulting with Ben Abbott: The Acromags in LIGO do not operate with regulated power. We could easily accomodate the standard regulator boards D1000217 in the chassis, which is probably a good idea if we want to place any custom electronics inside the chassis in the future, for example for whitening or active lowpass filtering. |
