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). CMX system is composed by electronic boards and by mounting devices that allow you to install it easily and quickly. In this manual you will find:

− an overview of the system architecture;

− a description of system components and how to configure them;

− notes about the installation of hardware, using the mounting accessories supplied by Cerberus Dati;

− power requirements and connections, to properly supply the CMX boards;

− information about connections characteristics e.g. cable dimensions and maximum lengths;

− external I/O connections characteristics;

− how to detect malfunctioning and problems during board operations.

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 CMX in the LMS/CMS network architecture is at the same level as CZ10 or CZ12 control panels. It interacts directly with the field devices and transmits upward the messages using a high-level protocol. 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 computerbased supervising system (LMS or CMS) (see Fig. 2.1) The CMX system architecture is different than those of CZ10 or CZ12. The CZxx panels can be connected to the gateway only in a point-to-point configuration: CMX can be connected in a multidrop configuration. The Gateway communicates using a 3-wire RS-232 serial protocol. The CMX communicate using a 2-wire RS485 serial protocol, that allows longer distances without modems. The IC-2 communication interface is the first device that constitutes any CMX network. It is connected on one side to the Gateway GW-00 Subsystem Pad or to the GW-01 asynchronous board and on the other side it communicates with the CMX boards. Due to RS-232 limitations, the IC-2 is usually located near the Gateway; you will find detailed information about cables and connectors in Section 3.2. The CMX are connected to the IC-2 in a multidrop configuration: on each line (i.e. to each IC-2) up to 16 CMXs can be linked. The connection among the CMX in the multidrop configuration guarantees the electrical continuity even if one of the CMX stops operating. No line breakdown can occur in most cases of CMX board failure. The maximum distance between the IC-2 and a CMX board is up to 1200 meters at 9600 baud. The boards can be powered using different power supply units, located near them. To CMX-24O can be connected up to 3 CMX-RB relay output boards and to CMX-16/8 up to 1 CMX-RB can be connected. The connection is implemented using a flat cable supplied with CMX-RB .

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 reset pushbutton

• the switch block marked SW1

• the switch block marked SW2

Although the CPU board layout is the same for all the CMX models, the boards are configured and operate differently in the three CMX models. The CPU board contains all the hardware and software needed for communications and interfacing. You can easily recognize the big CPU chip, and next to it the quartz crystal (XTAL) in its metal case. If you look at the board with the CPU chip at right, you can detect at the right of the quartz a small black pushbutton. This is the reset pushbutton, that starts the CMX diagnostics routines and reset the field status. This pushbutton has to pressed only when the CMX needs a full restart. When it is pressed, the status of all inputs is re-read.

At the right of the CPU chip, at the upper and lower side, there are two switch block, used to set:

− the baud rate (SW2-6, SW2-7, SW2-8) : see Annex A, Table A.1;

− the I/O status (normal/inverted) (SW2-1, SW2-2, SW2-3): see Annex A, Table A.2;

− the board network address (SW1-4, SW1-5, SW1-6, SW1-7, SW1-8) : see Annex A, Table A.3;

− the board type (SW1-1, SW1-2, SW1-3): see Table 4.1.

Five switches on the SW1 are used to set the board address (see Annex A, Table A.3). 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 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. If the switch is set OFF, the eight inputs corresponding to it are evaluated active when they are closed (this condition is stated as "normally open" in Table A.2 in Annex A). If the switch is set ON, the inputs are complemented, i.e. their active status corresponds to the open state (this condition is stated as "normally closed" in Table A.2 in Annex A). In the upper left part of board there are two double jumpers, marked JP1 and JP3. Each one has a "A" jumper and a "B" jumper. Their setting is as follows and must not be changed:

JP1 JP3

A OFF ON B ON OFF

Table 4.2 - JP1 and JP3 settings

The I/O board (CD 91200) of the CMX-24I is able to accept up to 24 inputs. On the board it is easy to recognize the two rows of twelve photocouplers each, the small blocks with four pins, the two LEDS blocks of 24 and 4 LEDs respectively, on the left board side and the DIN 64-pins connector on the right side. The 24 LEDs are linked to the I/O port. When a LED is ON this means that the input is closed at the corresponding input port. Note that the LED signifies only a physical condition (i.e. current flowing through the diode), while the logical meaning of the input is assigned by the switch setting (see Table A.2). Looking frontally to the LEDs rows, the four lower LEDs have the following meaning (Fig. 4.1):

− the upper left is the RS-485 line TX monitor: during normal operation it blinks according to the signals transmitted.

− the upper right is the RS-485 line RX monitor: during normal operation it blinks according to the signals received.

− the lower left is the power supply monitor: it must be steady ON when the CMX is properly powered.

− the lower right is the low voltage monitor: during normal operation it is OFF. It lights on when the power

supply voltage drops below the lower limit of 11.4 V.

The board layout is common with the other CMX models (CMX-24O and CMX-16/8). The CMX-24I however lacks the three IC marked on the PCB as U1, U2 and U3, as well as the related jumpers marked W25, W26 and W27. The only feature that can require a maintenance intervention is the fuse on the I/O board. The fuse is soldered to the board and it is intended for board protection and not for field protection. If the fuse blows out, probably there is something wrong with the board. Send it back to Cerberus Dati for maintenance.

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.

The I/O board (CD 91200) of the CMX-24O is able to drive up to 24 outputs. On the board it is easy to recognize the two rows of twelve photocouplers each, the small blocks with four pins, the two LEDS blocks of 24 and 4 LEDs respectively, on the left board side and the 64-pin DIN connector on the right side.

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

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. It is however possible to supply both LEDs and relay coils at the same voltage Vd that supplies the CMX. Table 5.4 shows the output electrical characteristics.

Feature Value Unit

Voltage - max 30 V DC Current - max 100 mA

Table 5.4 - Output electrical characteristics

To properly connect the output device, connect the positive polarity to the output device free end; the ground must be common between the output device and the CMX power supply. If you use a relay , a voltage suppression diode is needed to suppress the opening circuit voltage. The output board is equipped with 24 such diodes. You can use them in groups of eight by setting ON the jumpers marked W25, W26, W27 (see Table 5.5). When you use the internal voltage suppression diodes, the following precautions apply:

• all the pins belonging to the same octet must be at the same voltage

• the relay has to be driven at the CMX board power supply voltage

• no external voltage suppression diode is required

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. For each relay three screw are provided. For each output the rightmost screw (Fig. 7.1) is the common, the second screw is the normally closed contact and the third screw is the normally open contact. They are marked COM (for the common connection), NC (normally closed contact) and NO (normally open contact). The CMX-RB could be connected to the CMX-xx using the supplied flat cable, that must be used in conjunction with the CMX-MB mounting bracket (see Chapter 8). The CMX-RB is powered by the CMX-xx. The jumper marked J1 on the board is used to set the relays operating voltage. When the two rightmost pins are shorted by a jumper (the default condition), the relay board operates at 24 V (rightmost with reference to Fig. 7.1). In this configuration, the voltage regulator circuit in the upper right angle of the board, is active. Should you use a power supply that outputs 12 V max and should you have trouble with the relays, try to short the leftmost pins. In this configuration, the internal voltage regulation is performed and the relays are operated directly by the supply voltage.

The relay characteristics are listed in Table 7.1.

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. it is kept in stock) to avoid batteries damage. When battery operation is enabled the front panel LED marked BATTERY ON shows this status. A red LED (marked LOW BATTERY) lights on when the battery level is low. A green LED (marked POWER ON) shows the main (220 V) presence. A single CMX-PS can power up to 4 CMXs. If more than one CMX-PS is installed, they must be left floating (i.e. not grounded) in order to avoid problems with ground currents. Both input and output fuses are located on the front panel, for fast maintenance interventions. The CMX-PS has standard Europe-format dimension and it can be mounted either in the box along with up to 3 CMXs (CMX-RM) or in a standard 19" rack or using the metal housing provided with CMX-PS.

Fig. 8.2 shows in a side view of the CMX-PS the connections on the screw connectors that could be accessed on the back of the device. Fig. 8.2 is side view of the CMX-PS with the cover removed. You need to remove the cover to access the batteries. To remove the cover, unscrew the three cross-headed screws on the aluminium cover with holes and lift it. You can see the batteries and the electronic circuitry. The two sealed batteries (6 V-2.0 Ah) are connected in series. one cable runs from one to the other, connecting the positive and negative poles. The negative pole from one battery must be connected to the cable with the BLU band, that is connected to the power supply PCB. The positive pole of the other battery must be connected to the cable with the RED band, that is connected to the front switch. The cables are Faston terminated, so the battery replacement is matter of minutes.

ACCESSORIES

9 Accessories

9.1 The CMX-MB mounting bracket

The CMX-MB (CD91203/B) is an accessory that allows to mount easily any CMX model inside a cabinet or an existing housing, using the proper screw holes. The serigraphed panel mounted on the bracket shows the connections. The CMX-RB is composed by (see Fig. 9.1 and Fig. 9.2) :

• a plastic bracket with a rail to insert in the CMX board

• a backplane connector that joins the CMX board 64-pin DIN connector

• a screw terminal box, to connec t the I/O wires coming from field, the RS485 communication lines and the

supply voltage

• three connectors for the CMX-RB flat cables.

• a plastic serigraphed panel that shows the connector layout

The output signals that are available on the screw terminal are the same available on the flat cable connectors. The last allow an easier and faster connection should you use the CMX-RB . Fig. 9.3 shows the minimum distance between two CMX-RB , while Fig. 9.4 shows the CMX board mounted in the CMX-MB.

9.2 The CMX-BP Connection backplane

The CMX-BP (CD91202) is an accessory that allows to connect the CMX-xx to the I/O wires, the communication lines and the voltage supply. The CMX-BP is composed of a 64-pin DIN connector on one side and two rows of screw connectors on the opposite side. Fig. 9.5 shows the connector layout and the dimensions. The CMX-BP can be used by itself (it can be mounted on an existing panel by screws) or in the CMX-SB and in the CMX-RM.

Fig. 9.5

9.3 The CMX-SB Single Box

This accessory is a plastic box (see Fig. 9.6 and Fig. 9.7 for the dimensions) that can house one CMX board of any model. The CMX-SB is composed of the box body, a serigraphed aluminium front panel and the box back. Moreover, to properly mount the CMX you need the CMX-BP backplane. First of all, you have to make a hole in the base for the cables and then to mount it on the wall. Then connect the cables to the backplane connector. Remember that the screw part of the connectors is detachable. Insert the connectors in their place and screw the box body to the box back, using the two internal screws supplied. Insert the CMX board and mount the front panel.

9.4 The CMX-RM Rack Mount

This accessory is a plastic box that can house up to four CMX boards of any model. The CMX-RM is composed of the box body that is hinged to the box back and by a serigraphed aluminium front panel. Moreover, to properly mount the CMX you need as many CMX-BP backplanes as CMXs you wish to mount. To let the box body rotate around the hinges, put the slit of the hinge screw in horizontal position, pull down the hinge in order to free the pivot and then rotate the box. To tighten the box again, repeat the operations in the inverse order. To mount the CMX-RM , you have to make a hole in the box back for the cables and then to mount it on the wall. Then connect the cables to the backplane connector. Remember that the screw part of the connectors is detachable. Insert the connectors in their place, rotate the box body at its place around the hinges and tighten it. Insert the CMX boards and mount the front panel.
