1.1 Scope of this document This document describes the Cerberus Dati's CMX Input Output Multiplexing System. CMX is a system, composed by a set of components, that will allow your LMS or CMS system to manage digital I/O signals. Using the CMX you can interface existing old security panels or technological devices.
Like CZ10 and CZ12, the CMX communicates with LMS/CMS through the gateway, a dedicated piece of hardware manufactured by Cerberus Dati that manages the communications to and from the control panels and the computer- based supervising system (LMS or CMS) (see Fig. 2.1) The CMX system architecture is different than those of CZ10 or CZ12.

THE IC-2 COMMUNICATION INTERFACE 3 The IC-2 Communication interface The IC-2 appears as a small plastic box that contains the electronics. A green LED on the front panel is lighted when the power is on. The box can be opened exerting pulling the upper side from the lower side; there are no blocking screws. Fig.

Should they be different, the system will not operate.
THE CMX-24I BOARD 4 The CMX-24I board The CMX-24I is the CMX board with 24 inputs and no outputs. The CMX-24I is composed of a CPU board (marked CD91201) and an I/O board (marked CD91200), connected together (see Fig. 4.1) for board layout and assembly). The important features to be detected on the CPU board are: •...

The value must be higher than the minimum current value stated in Table 4.4 to let the CMX detect the input status change.
THE CMX-24O BOARD 5 The CMX-24O board The CMX-24O is the CMX board with 24 outputs and no inputs. The CMX-24O is composed of a CPU board (marked CD91201) and an I/O board (marked CD91200), connected together (see Fig. 5.1 for board layout and assembly).

THE CMX-24O BOARD The outputs are optoisolated open-collector type. You can drive by them a relay in order to have a relay output (the standard relay output CMX-RB is described in Chapter 7). Fig. 5.2 summarize two of the possible output configurations available. In case (a) the relay coil is supplied at the V rl voltage, that could be different from the CMX power supply voltage V d .
THE CMX-16/8 BOARD 6 The CMX-16/8 board The CMX-16/8 is a CMX board with 16 inputs and 8 outputs. The CMX-16/8 is composed of a CPU board (marked CD91201) and an I/O board (marked CD91200), connected together (see Fig. 6.1 for board layout and assembly). The important features to be detected on the CPU board are: •...

THE RELAYS OUTPUT BOARD CMX-RB 7 The relays output board CMX-RB The CMX-RB (CD91205) is a relay output board that converts the CMX open collector output into a relay output. The CMX-RB layout is sketched in Fig. 7.1; the following description assumes you are looking at the board with the orientation of the drawing.
8 CMX-PS Power supply unit The CMX-PS is a power supply unit designed to be used with Cerberus Dati CMX units. The CMX-PS is a compact, modular and reliable uninterruptible power supply with two sealed batteries included. CMX-PS switches automatically to battery supply when the main goes off if the front panel switch was set ON.
