# SutterLambda

 Summary: Interfaces to Sutter Lambda 10 controllers, Lambda SC controller, and DG4 Authors: Nenad Amodaj Maintainers: Arthur Edelstein License: BSD Platforms: Windows, Mac OS X and Linux (only serial port, no parallel port or USB) Devices:

## 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 128000 for USB ports (which use a build-in USB-serial converter, drivers can be found here)

### 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.

### Lambda SC

For the Lambda SC Smart shutter controller, select the “Shutter-A|Lambda 10 shutter A” in the Hardware Configuration Wizard.

## Troubleshooting

### Wheel re-homing during imaging

You need to 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.

See the Operation Manual (available at http://www.sutter.com/) section “Helpful Tips about Filter Wheel Movement Errors”.
