This is a product-dependent reset: flex I/O defaults back to TTL input, contact closure defaults to open, relays are reset to open, current sensing thresholds are reset to default, receive
time-outs are reset back to defaults, port redirects are terminated. Consult product-specific documentation for settings affected and default values. Excludes IP settings such as IP
address, subnet mask, gateway IP address, and IP security-level table, and does not remove the file system.

This command is intermediate between the ZXXX and ZQQQ commands. It is an absolute system reset excluding IP settings (IP address, subnet mask, gateway IP address, unit
name, DHCP settings, port mapping). This allows you to maintain communication with the device. This reset is recommended after a firmware update. It erases the file system.
