INTRODUCTION 1 Introduction 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. You can collect from them digital inputs (dry contact or open collector signals) and send to them digital outputs (relays or open collector outputs).
SYSTEM DESCRIPTION 2 System description The CMX systems is composed of • active components electronic boards CMX-24I, CMX-24O, CMX-16/8 communication interface IC-2 relay output CMX-RB • passive components accessories for board mounting: CMX-SB, CMX-MB, CMX-RM, CMX-BP The network architecture that follows apply only to the active components; both active and passive components will be described in the following paragraphs, from 2.2 to 2.9.

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. 3.1 Inside, the printed circuit board is marked CD95204/B; the only features relevant to the installer are the connector's block and the jumpers (see Fig. 3.2).

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 CMX-24I BOARD The switches SW1-1, SW1-2 and SW1-3 are used to define the board type. For the CMX-24I they must have the setting shown in Table 4.1. SW1-1 ON SW1-2 ON SW1-3 ON Table 4.1 - Board type The switches SW2-1, SW2-2 and SW2-3 are used to define the meaning that the CMX firmware assign to the input status. The meaning is assigned to the inputs in groups of eight, and so 3 switches are enough to define the meaning of 24 inputs.
THE CMX-24I BOARD Fig. 4.2 Refer to Chapters 8 and 9 of this manual for actual connections of the board to external devices. The power supply must have the characteristics shown in Table 4.3. Feature Value Unit Voltage - min 12 V Voltage - max 28 V Current - idle Current - max 80 @12 V mA 60 @28 V mA 360 @13.8 V mA 420 @27 V mA Table 4.3 - Power supply characteristics The inputs can be : • Open collector • Dry contacts Fig. 4.2 shows two of the possible input configurations. Table 4.
THE CMX-24I BOARD Feature Value Unit Voltage - min 12 V Voltage - max 28 V Maximum internal resistance 2.2 kOhm Current - min 6 @12 V mA 12 @28 V mA Table 4.4 - Input electrical characteristics The internal resistance can be used to evaluate the current that will flow in the external circuit. 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 Five switches on the SW1 are used to set the board address. Five binary switches allow 25=32 addresses, but remember that only 16 CMX can actually be addressed on a single communication line. Never use addresses above 15 (0F Hex); the SW1-4 setting must be always ON. The switches SW1-1, SW1-2 and SW1-3 are used to define the board type. For the CMX-24O they must have the setting shown in Table 5.1. SW1-1 OFF SW1-2 OFF SW1-3 OFF Table 5.
THE CMX-24O BOARD FEATURE VALUE UNIT Voltage - min 12 V Voltage - max 28 V Current - idle Current - max (no output connection) Current - max (with 24 relay output activated) 70 @12 V mA 60 @28 V mA 240 @12 V mA 200 @28 V mA 550 @12 V mA 470 @28 V mA Table 5.3 - Power supply characteristics E1110A.DOC Data and design subject to change without notice.

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 Vrl voltage, that could be different from the CMX power supply voltage Vd. In (b) the external LED is supplied at the voltage Vld: this voltage too could be different from Vd.

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 CMX-16/8 BOARD Five switches on the SW1 are used to set the board address. Five binary switches allow 25=32 addresses, but remember that only 16 CMX can actually be addressed on a single communication line. Never use addresses above 15 (0F Hex); the SW1-4 setting must be always ON. The switches SW1-1, SW1-2 and SW1-3 are used to define the board type. For the CMX-16/8 they must have the setting shown in Table 6.1. SW1-1 OFF SW1-2 ON SW1-3 ON Table 6.

Refer to them for details about the CMX-16/8 I/O characteristics. E1110A.
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. The CMX-RB is mounted on a plastic support that allows you to mount the board on a DIN rail. The eight black blocks are the relays; the output connections can be done using the connectors.
CMX-PS POWER SUPPLY UNIT 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. The switch on the front panel enables/ disables battery intervention. The switch must be set OFF when the power supply unit is not operating (e.g.
