JMRI Hardware Support - TracTronics SECSI System

# Hardware Support: TracTronics SECSI System

JMRI can connect to TracTronics SECSI system Nodes.

## Limitations

As of 2016 TracTronics SECSI is no longer online. It previously appeared at www.tractronics.com . A archived version of their website is available on the Internet Archive.

SECSI support will remain in JMRI, but it's unlikely to be updated any further if there's no active manufacturer of components.

## Connecting

You tell JMRI about how to connect to your SECSI hardware via the Connections pane in the Preferences window. Select "SECSI" as the manufacturer name.

### Naming

The system letter is "V", so for example the first Sensor on node 5 would be "VS5001".
