CDI-46 Installation and Setup Guide V1.0 3
Introduction
The CDI-46 is an optional digital interface card designed specifically for use with the Cloud 46-120 range of
Multi-Zone Mixer Amplifiers. The card has an Ethernet port and an RS-232 port, allowing the Mixer Amplifier’s primary functions
to be controlled from external systems (Crestron, AMX, etc.) using the Cloud Serial Protocol, via either an Ethernet network
link or an RS-232 serial interface. The card can also act as an Ethernet-to-serial bridge, converting Ethernet commands from a
control system into RS-232 data for other non-Ethernet equipped equipment (e.g., projectors).
The CDI-46 is also fitted with a Cloud Digital Paging interface (the
CDPM/PM INPUT). This provides the simplest method of
connecting Cloud PM Series Paging Microphones, requiring only a single standard Cat 5 cable.
When installed, the CDI-46 permits the following 46-120 functions to be controlled remotely:
1. Music source selection for each zone
2. Music level in each zone
3. Music muting in each zone
4. Muting of individual microphones in each zone
5. Activation of Mic 1’s paging access
6. Triggering of messages stored in a PM-SA paging microphone
Physically, the CDI-46 is a small printed circuit board (PCB), which is retrofitted internally in the 46-120 such that the
ETHERNET INTERFACE, CDPM/PM INPUT and RS-232 connectors are available at the rear panel.
Scope of this Guide
This manual describes the mechanical installation of the card and the connections that need to be made to it. It also explains
the various configuration options that the card offers, and how to set these using the simple built-in web server, and the various
jumper settings that need to be made to the 46-120 to achieve correct operation.
The manual also gives a general overview of the Cloud Serial Protocol as used by the CDI-46, and some examples of the most
useful commands. This information should be adequate for many installations, but please note that a full description of the
protocol is beyond the scope of this manual. The full CDI-46 Serial Control Protocol document is available in PDF format via
the browser interface; alternatively, it can be downloaded from
www.cloud.co.uk .
