There are a variety of settings in the Slink-e that you can set with the programming interface. For each of them, there is a startup default: the value of the setting after startup of the Slink-e and before you execute a command to change it.
You can set the startup defaults too, on a Version 2.0 or later Slink-e. The Slink-e remembers the startup defaults in SEEPROM memory.
The value of the startup default before you've set it to anything else, i.e. with which the Slink-e comes from the factory, is the factory default.
On Slink-e's earlier than Version 2.0, the startup default is always the factory default.
"startup" is when the Slink-e powers up or you execute a reset command.
The factory defaults for the startup defaults are documented in the sections that describe the commands for overriding the startup defaults. E.g. the factory default for the startup default for the baud rate is covered in the section on the Set Baud Rate command.
Use the Save Defaults command to set the startup defaults. It saves all the current settings as the startup default settings.
There is no way to restore the startup defaults to the factory defaults implicitly. You can, of course, set the startup defaults explicitly to what the factory defaults are.
The settings that have startup (and factory defaults) are:
