Hello,
I have three NF CA5351 Current Amplifiers and use Ethernet/LAN to access them remotely. (product webpage:
https://www.nfcorp.co.jp/english/pro/mi/loc/pre/ca5351/index.html )
For some reason which I don't know, they would behave erroneously. Only one of them is accessible remotely, and after several seconds, the accessible one will change. That is, only no. 1 is accessible, several seconds passed, only no. 2 is accessible, several seconds passed, only no. 3 is accessible, several seconds passed, ...repeat the above sequence...
I try rebooting the devices, doesn't work.
The solution I found is: Unplug the network cable, change the IP address of the device, change the IP address back to the original setting, plug the network cable.
Then everything is fine.
Does anyone have any idea about this bizarre behavior?
Best regards.
