46-120 Installation and User Guide V1.2 13
16. MUSIC MUTE – 2-pin 5 mm-pitch screw terminal connector for connection of external emergency muting relay
(e.g., fire control panel). See page 20.
17. REMOTE POWER DOWN – 2-pin 5 mm-pitch screw-terminal connector allowing the 46-120 to be put into
Standby Mode from external control systems. See page 20.
18. Mains – IEC receptacle for AC mains. See page 14.
19. FUSE – mains fuse. See page 14 for fuse details.
The following rear panel items are only present when the CDI-46 Digital Interface Card is fitted:
20. CDPM/PM INPUT – RJ45 Cloud Digital Paging interface; PM Series* microphones (excluding the PM1) may be
connected here, using screened Cat 5 cable. See page 16 for more information.
21. ETHERNET INTERFACE – standard RJ45 network connector allowing the 46-120 to be controlled and configured
from external equipment using TCP/IP commands. It can also be used as an Ethernet-to-serial bridge to pass TCP/IP
commands from third-party control systems to the RS-232 connector [22].
22. RS232 – a 3-pin 3.5 mm-pitch screw-terminal connector providing a bi-directional RS-232 interface. This permits
control of the 46-120’s functions from an external system and can also transmit serial commands to third-party
equipment in response to Ethernet commands generated elsewhere.
* The earlier Cloud CDPM range of Paging Microphones is also compatible with this interface.
