EFI gateway with M4000 and UE403 switching amplifier
In this case the M4000 receives the muting signals from the UE403 (address 14). The EFI
gateway receives the status information (e.g. on the OSSDs or on the muting lamp) from
the M4000 (address 1) and from the UE403 (address 14). The EFI gateway routes this
information to the (F)PLC.
With M4000 firmware < 1.50 the device address of the EFI gateway must be re-configured
to 13 before commissioning it with other devices, so that the exchange of data does not
collide with the UE403. The address 13 is valid for both EFI strings. For this reason it is
possible to connect to the second EFI string either an identical UE403/M4000 system or a
product that can receive the address data from address 13. From firmware 1.50 this
restriction no longer applies as the communication addresses between UE403 and
M4000 can be changed.
The combination of M4000 and UE403 switching amplifier on one EFI string and a further
M4000 on the second EFI string is, for example, with M4000 firmware < 1.50 not possible
technically.
