Device Configuration

Serial port issues

Sutter devices use a straight through (i.e., not null modem) DB9 serial cable. The default baud rates are 9600 for serial ports and 128800 for USB ports (which use a build-in USB-serial converter)

Wheel speed

95% of the time speed #1 works best (#0 being the fastest, which only works with an empty wheel). If speed #1 does not work you can try the slowest (speed #7 IIRC). Best practice is to set the desired wheel speed during startup, i.e. in your Startup Preset of the System Group.


Wheel re-homing during imaging

First make sure your firmware is up-to-date. Lambda 10-B controllers with firmware < 2.22 were known to have this issue.

Then one should just optimize the filter speed setting if you ever encounter the dreaded re-homing sound due to the wheel failing to move to a filter position during Multi-Dimensional Acquisition. The wheel itself has a resonance frequency associated with the load of filters. Practically one finds the ideal speed by empirically checking which speed introduces the least vibration.
