Important Preliminary Notes
- To update Ultra 300 and eIO-CPU Controllers, simply download the .img file and upload it through the web interface. No additional software is required.
- To update Netbell-2, Netbell-K, Netbell-NTG, FARGO, iTrixx-NHM, and KODA Controllers you MUST update BOTH (When there are differences for some specific devices, they will be noted in the text) in the following order:
- SERVER software (.cry file)
- Webpage software (.bin file)
- To update iTrixx-WFNM you need to upload only SERVER software (.cry file)
- Software compatibility notice: You cannot load Netbell software onto a Hourmeter or regular I/O controller. The software type is hard-coded to the device at the factory.
