Keita got the TMSX OSEMs connected up and asked me to see if the readouts were reasonable.

Unfortunately there is a large amount of HF noise at assorted frequencies up to about 600 Hz.  DTT and DataViewer views are attached.

The first quadrapus (F1, F2, F3, LF) is several orders of magnitude worse. When the quadrapusses were swapped the noise went with the quadrapus.

There doesn't appear to be a valid DC signal underlying the noise, except possibly for F2.
