METIS M308 / M309 / M313 / M316 / M318 / H309 / H316 / H318 (12-pin)
When operating multiple devices (up to 32 are possible), each device needs to assign its own address (directly
on the device or via software SensorTools), under which it can be addressed later. For this purpose, initially,
each device must be connected individually and provided with an address (00-97). After that, all devices can
be connected. If specific parameters for all devices should be changed simultaneously, the global address 98
is used (there is no response from the device). If the address of a device is unknown, you have the opportunity
to address each device independently of the set address with the global address 99 (connect only one device).
