Cloud Electronics CDI-S200 - Manual (Page 4)

CDI-S200 Installation Guide v1.0 4
Introduction
The CDI-S200 is an optional RS-232C interface
card designed specifically for use with the
Cloud CX263 Zone Mixer. It allows the
CX263 to be controlled by third-party systems
(such as Crestron, AMX, etc.), using RS-232C
serial data.
When installed, the CDI-S200 permits the
following CX263 functions to be controlled
remotely:
•
Music source selection for each zone
•
Music level in each zone
•
Music muting
•
Muting of individual microphones
•
Activation of Mic 1’s paging access
Physically, the CDI-S200 is a small printed
circuit board (PCB), which is retrofitted
internally in the CX263 such that the 9-pin
D-type RS-232C connector is available at the
rear panel.
Scope of this manual
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 the various jumper and switch
settings that need to be made to the CX263 to
achieve correct operation.
The manual also gives a general overview of
the RS-232C serial control protocol used by
the CDI-S200, and some examples of the most
useful commands. This information should be
adequate for most installations, but please note
that a full description of the RS-232C protocol
is beyond the scope of this manual. The full
protocol can be found at
www.cloud.co.uk .

Installation
Configuring the CDI-S200
Before installing the CDI-S200 in the CX263,
various jumpers on the PCB need to be set
correctly. (This step should be performed first
because the PCB is installed in the CX263
upside-down, and access to the jumpers is very
difficult once it is in position.)
The jumpers are concerned with setting
the parameters of the serial port (see “Port
parameters” on page 8). The port parameters
should be set to suit the control system
being used. It is quite likely that the factory
default settings will provide correct operation;
nevertheless, it is important to check that this is
so and alter the settings if necessary.
To move the jumpers, use small pliers to gently
pull the jumper off the header pins and replace
in the correct position. Do not use undue
force, and do not use pliers which are too big.
There are four jumpers, J1 to J4.
