I'm currently trying to configure a CR1000 and a NL241 to have seperated power source but still have the CR1000 to control when the NL241 wifi is up or not. Before today, the CR1000 was always using his own power source throught the CS I/O ports to feed the NL241, but we would like them to have seperated power source so that, if the NL241 use too much battery and use all its battery, it will only stop working and the CR1000 will still be operational.
Thanks for your help
Refer to page B-3 in the NL241 manual. There is a jumper you can change to prevent the NL241 from taking power through CSIO. You can then still use CSIO for the connection to the CR1000. The IPNetPower instruction in the datalogger will allow putting the NL241 to sleep.
Thank you very much. It works.
