What is Auto Ping and Programmable Reboot?

When auto ping function is enabled, BE-M104 will automatically send ping command

to other device. When the external device becomes unresponsive, BE-M104 will run a set of

preloaded program, which can be set by your customized reboot sequence. You can either set a

fixed IP address or a domain name for auto ping.

address and registers, but rather work with human natural language.
