What Does My ENET Device Store After the Power Is Turned Off?Hardware: Instrument Connectivity Other>>Ethernet>>GPIB-ENET/100
Problem: What does my ENET Device store after the power is turned off? How secure is my data? Solution: All TCP/IP data sent between your computer, the ENET Device, and your instrument is stored completely in volatile memory. Since volatile memory requires a steady flow of electricity for each bit to hold its current state, this data is permanently lost once the ENET Device is turned off. An ENET Device will also contain some non-volatile memory. This memory remains after the ENET Device is turned off. This non-volatile memory stores the firmware, as well as network information (i.e. the static IP address or whether the IP is assigned by a DHCP server). This network information can be reset to the factory default settings (as defined on the base plate label) by holding the CFG RESET button for 3 seconds when you POWER ON the ENET Device. This can be useful if you wish to delete the static IP address you assigned the ENET Device. In contrast, simply holding down the CFG RESET button after the power is already ON puts the ENET Device into network configuration mode and does not reset the network configuration. In summary, if you reset your ENET Device during power on and turn off the device, then all sensitive user data will be destroyed.
