6.2.5.
MTP-address
The MTP address setting regulates communication over the interface with the receiver. The PC, as the master
device, sends a transmission with the device address that is read with each MTP200 (slave) by using the COM
interface in case of an individual compound or using the RS485 interface in case of a multidrop connection.
Only the MTP device with the set address communicates to the master. Consequently, MTP devices with same
address may not be connected.

field;
2. Setting of the current device address in the
Interface
field;
3. Execute the Program MTP command and confirm;
4. Read back the MTP data with the command Read MTP data (after finishing these actions, the
new device address is indicated in the field MTP identification).
For a successful device connection the 3 digits address in the
MTP identification
field and
