Hardware write protection via DIP switch

If switch 1 of the 6-pin DIP switch is in the "on" position, hardware write protection is activated
and the device cannot be configured.
To configure the device, switch 1 must be in "off" position.
After successfully configuring the device, it is recommended that you activate hardware write
protection by moving the switch to the "on" position.
(Devices are generally shipped with hardware write protection deactivated.)
