Additional Compatibility Information


LoggerNet provides support for communicating with our data loggers over the the Iridium network using the Iridium 9522B. LoggerNet provides user control by allowing direct communications with the remote station using the Iridium Dial-up or RUDICS services. LoggerNet can run unattended, providing scheduled communications for data and image collection, as well as remote station administration.

Enclosure Considerations

The COM9522B requires a desiccated, non-condensing environment; a Campbell Scientific enclosure is recommended. Grommets and screws are provided to attach the COM9522B to the backplate of our enclosures.
