-=== Scan output connector === 
- 
-JST XH connector on a three-colored (black, green, orange) wire harness. Cobbled together by q3k, will be used for image acquisition. 
- 
-^ Pin number ^ Wire color ^ Description ^ 
-| 1          | Black      | Ground      | 
-| 2          | Green      | H or V sync | 
-| 3          | Orange     | H or V sync | 
- 
-H/V sync needs to be figured out (by following the wires or with an oscilloscope). 
- 
-H/V sync values are ramps +/- 5V (opamps are supplied +/- 8V). 
- 
-The wires all go to U54 (opamp input) on PK00492 (the scanning board). This opamp is used to read back data from the EK9 connector. This connector allows for chaining scan/detector though the BCX x-ray unit. There might be signal integrity issues with tapping the sync data like this, we'll see.

 +==== Open Beam Interface (digital acquisition) ====
 +
 +Use [[https://git.fa-fo.de/fafo/jeol-t330a/src/branch/main/obi/microscope.toml|microscope.toml]] from [[https://git.fa-fo.de/fafo/jeol-t330a]|our repo]]. There's also a obi.nix next to it to build the OBI codebase on Nix.
 +
 +Connect the OBI to power (currently through bundle of DIN SMPSes next to OBI), connect the OBI to the WHLE-LSE-1088A box via USB (or connect directly to your PC and run your own obi-server, after editing microscope.toml). Run GUI against microscope.toml.
 +
 +TODO: move to dedicated mini PC (q3k ordered one).
