1Introduction

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

2System 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 computer-

based 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.

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 following connections are provided:

−RS485 communication line (towards CMX,Westinghouse 422)

−IC-2 power supply

−RS232 communication line (towards Gateway)

The jumpers let you set:

−Baud rate: jumpers A, B, C, D, E, F - refer to Table 3.1.

The RS-232 communication line toward the gateway is a 3-wire connection.

4The 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.

Fig. 4.1

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

E1110A.DOC Data and design subject to change without notice. Supply subject to availability

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

AOFF ON

BON 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.

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. Moreover, the

external device must be able to withstand that current without damage.

5The 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 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. I 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. Be careful in using the reset pushbutton on the CPU board of CMX-

24O: when it is pressed all the outputs are set into a non-active status. A new command from the supervision

center is needed to re-activate them.

At the right of the CPU chip, at the upper and lower side, there are two switch blocks, 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 5.1.

THE CMX-24O BOARD

20[51]Data and design subject to change without notice. Supply subject to availability

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 5.1- Board type

The switches SW2-1, SW2-2 and SW2-3 are used to define the meaning that the CMX firmware assigns to the output

status. The meaning is assigned to the outputs in groups of eight, and so 3 switches are enough to define the meaning

of 24 outputs. If the switch is set OFF, the eight outputs corresponding to it are evaluated active when they are closed

("normal" condition in Table A.2). If the switch is set ON, the outputs are complemented, i.e. their active status

corresponds to the open status. Table A.2, in Annex A, summarizes their meaning.

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

AOFF ON

BON OFF

Table 5.2- JP1 and JP3 settings

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 24 LEDs are linked to the I/O port. When a LED is ON this means that the output is closed at the corresponding

output port. Note that the LED signifies only a physical condition (i.e. current flowing through the diode), while the

logical meaning of the output 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. 5.1):

−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

−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.

marked on the PCB as U1, U2 and U3 and the related jumpers marked W25, W26 and W27.

The only feature that can require a maintenance intervention is the fuse on the lower right angle. 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.

Refer to Chapter 8 of this manual for actual connections to external devices.

The power supply must have the characteristics shown in Table 5.3.
