3.5.3 Connections for alarm management

See pin configuration table for the DB25 connector.

3.5.3.1 Alarm contacts

WARNING! Do not energise the alarm contacts! The sensors (or the alarm system in use) should supply

a dry contact. To manage the alarms correctly, be very careful when configuring the alarm parameters at the

matrix programming stage.

3.5.3.2 Auxiliary contact (alarm relay)

The SM84A / SM164A matrix can be used to control an auxiliary contact (relay) that is activated when there is

an alarm, if properly configured at the matrix programming stage. The auxiliary relay contacts are at pins 21 and

22 of the DB25 connector.

3.5.3.3 External reset

The reset impulse is recognised on the falling or rising edge (which can be set at the matrix programming

stage).

Pin 17 of the DB25 connector is associated with External Reset of the alarm condition and the ground reference

is pin 18.

3.5.4 Connecting the matrix to the peripherals

3.5.4.1 Control keyboards (Keyboard lines)

All the keyboards specified in section 2.2 Connectable devices and the SM84A / SM164A video matrix can be

connected by telephone cable using the 4 RJ-11 sockets called KEYBOARDS.

They can be connected directly using the 1.5m cable (supplied with the control keyboards) for short distances,

or, for longer distances, using the RJ-jack wall-mounted boxes (supplied with the control keyboards).

This is not applicable to the previous series keyboards, which require a communication interface because they

do not have RS485 (except for the DCS3 model).

Moreover, the DCTEL and DCBD and Linxs series keyboards can be powered directly by the matrix.

All the keyboards should have transmission rate settings that are compatible with the settings made for the

matrix at the programming stage. See the respective manuals for the keyboard setup.

3.5.4.2 Telemetry receivers (AUX line)

All the receivers specified in section 2.2 Connectable devices and the SM84A / SM164A video matrix can be

connected by telephone cable using the RJ-11 socket called AUX.

They can be connected directly using the 1.5m cable (supplied by the manufacturer) for a test or, for longer

distances, using the RJ-jack wall-mounted boxes (supplied by the manufacturer) and referring to the following

table:

RS 485 matrix (AUX line) – Receiver connection

MATRIX RJ-jack 1 RJ-jack 2 RECEIVER

RS485-A White ----------------- Blue RS485-A

RS485-B Yellow ----------------- Black RS485-B

All the receivers should be set up for RS485 communication mode and with a transmission rate that is

compatible with the setting made for the matrix at the programming stage.

See the respective manuals for configuring the receivers.

There are two possible ways of connecting the receivers to the AUX line:

 Receivers in cascade (Point-to-point connection)

 Receivers on the same line (Multi-point connection)

Page 13 MNVCSM84A_1511_EN

Point to point connection

This type of connection allows the AUX line to be used to control one or more receivers arranged in cascade

(point-to-point type connection). The AUX line of the matrix should have the termination resistance inserted (see

section 3.4.3). Each receiver in turn should have a RS485 line termination resistance inserted. Each receiver

should have a different address. Configure the receivers with RS485 type communication with the same baud

rate and protocol (Videotec or MACRO) as the Matrix AUX line.

Internally, the receivers can regenerate the received signal and send it on along a new communication line to

the next receiver. Each of the three line sections (L1, L2, L3) is considered independent, and connects only two

devices point-to-point, both with the load inserted, for a maximum distance of 1200 metres. The Matrix - R3

receiver distance can therefore be up to 3600 m (1200 m between the Matrix Aux line and receiver R1, 1200 m

between receiver R1 and receiver R2, and a further 1200 m between receiver R2 and receiver R3, for a total of

3600 m).

N.B. For the connection in question (point-to-point), faulty operation of one of the devices will cause faults in the

receivers that follow.

Multipoint connection

This type of connection allows the AUX line to be used to control one or more receivers connected on the same

line (multi-point connection).

Connect the receiver on the RS485 communication line with the same AUX matrix line baudrate and protocol

(Videotec or MACRO).

For each line the following should be taken into consideration:

 the Aux Matrix line should have the load inserted (see section 3.4.3 Inserting the load on the AUX line)

 only one of the receivers (the one at the end of the line) has the load inserted.

 the total length of the line should not exceed 1200 m.

 each receiver should have a different address

Receivers R1, R2 should not have the termination resistance inserted. The maximum length of the line, from

end to end (from the matrix AUX line to receiver R3), is 1200 metres.

N.B. For the connection in question (multipoint), a fault in one of the devices does not affect the other receivers.

stage. Connect the VCR input video with output video n°4 of the matrix (VCR dedicated output). For the VCR

trigger on the other hand, refer to the following connection table:

Pin 20 – Ground GND ------------------------- Ground pin

3.5.4.5 PC

It is possible to connect a PC for remote control of the matrix or for the firmware update using a standard 9-pin

serial extension cable (DB9M - DB9F) and connecting it to the matrix DB9 (“PC”) socket.

If the Macro communication protocol, given in the appendix, is used it is possible to completely control the

matrix and record noteworthy events when necessary.

4 Matrix operating features

4.1 Video input management

4.1.1 Automatic switching sequences

The automatic switching sequences are groups of input videos that are displayed consecutively in the

order and for the length of time defined by the operator. Each switching sequence consists of a minimum of 1

and a maximum of 16 program steps (identified by the letters from A to P).

Each step describes:

 the input to be viewed

 the viewing time, from 1 to 300 seconds.

There are no restrictions to programming the switching sequence: an input can even be repeated more than

once, as shown in the example below:

Step Input Length

Comment

A

1 2 Input 1 is on view for 2 seconds

B

2 4 Input 2 for 4 seconds

C

5 7 Input 5 for 7 seconds

D

- - - Step D is ignored and will be jumped

E

2 5 Input 2 is on view again for 5 seconds

F-P

- - -

If there are no further program steps, the automatic switching sequence

will resume from step A.

4.1.2 Day and night automatic switching sequences

Two different switching sequences can be defined for each outlet. This makes control of the infrastructures

easier during the day (when there is usually personnel on the premises) and at night (when control would be

better on the outer perimeter or at critical points around the installation).

During configuration, it is necessary to define the start and end times of the daytime switching sequence: the

night-time sequence will be enabled for the rest of the 24-hour period.

Warning! If the night-time sequence is not used (only one automatic viewing sequence is defined for the

whole 24-hour period), the start and end of the daytime switching sequence should be defined as 00:00 and

23:59 respectively. If the matrix seems to have an operating fault this may be due to an error in configuring the

daytime sequence start /end time.

4.1.3 Manual selection

From the keyboard, the operator can directly select a desired input, interrupting the automatic switching sequence.

A specific input video is always selected with reference to the active monitor: if the keyboard is authorised to

control more than one monitor only the “active monitor” (the last one to be selected) will be involved in the input

video selection.

The local keyboard and the remote DCTEL and DCBD keyboards can be used to control all outputs. Keyboards

DCJ and DCK can be configured to restrict access to a set of output videos dedicated to each operator, so as to

prevent unauthorised personnel from operating on all outputs.

4.1.4 Using the Inc/Dec keys

The Inc/Dec keys can be used to block an automatic switching sequence on one input and, where appropriate,

to select the next/previous input video (following the preset order for the switching sequence in progress)

without having to use the numeric keypad to select an input.

4.1.5 Output video dedicated to the VCR

Output video n°4 of matrices SM84A and SM164A is dedicated to the VCR if it is enabled. In this case control of

the VCR channel is only subject to the trigger impulse itself. Any command that may be sent from the keyboard

concerning this channel will therefore be ignored.

4.2 Alarms

The matrix provides a DB25 alarm connector, to which 8/16 (depending on the SM84A / SM164A model)

alarm contacts ("alarm input") can be attached, one for each of the input videos of the video device.

When an alarm is activated:

 the keyboards able to display the alarm condition can activate a warning buzzer and may also show the

alarm status with a display message or a flashing LED (this type of operation is determined by the

characteristics and configuration of the individual keyboard).

 each output that is enabled for recognition shows the video signal corresponding to the latest recognised

alarm in order of time; if an output is not enabled for recognition of the alarm condition, the alarm will not be

shown on the video

 the alarm relay will be closed (auxiliary contact) and in some cases a warning buzzer is activated inside the

matrix, if this is allowed for by the alarm contact configuration

 the text identifying the corresponding input is accompanied by the word “ALARM”.

Alarm status will be stored internally and will be kept, even if there is a temporary interruption to the matrix

power supply. Warning! The alarms must be configured with special care, because a mistake in their settings

could cause faults in operation that are difficult to identify.

4.2.1 Alarm contact types

Each individual alarm contact can be defined:

 normally open (N.O.): the alarm condition is recognised when the alarm contact is short circuited to the

common alarm pin

 normally closed (N.C.): the alarm condition is recognised when there is a break in the contact between the

alarm and common alarm pin

 not used: the alarm contact is ignored.

Warning! Pins that are not connected to any alarm contact should be configured as NOT USED.

See the following example to understand how the alarm contacts function:

Alarms normally open

: the contacts are

disconnected from the common alarm pin.

When the contact is closed, alarm number 3 is

recognised.

Alarms normally closed

: the contacts are

connected to the common alarm contact (pin

23-24-25). When the connection opened,

alarms 1 and 3 are recognised. This

configuration is also able to recognise as an

alarm a possible break in the cable

connecting the sensor and the matrix.

4.2.2 Alarm types

The alarm signal can be considered CONTINUOUS or IMPULSIVE.

The difference lies in how the matrix behaves when the alarm signal ceases:

 impulsive alarm: the matrix remains in alarm status, waiting for a reset (from the keyboard, external or timed)

 continuous alarm: the matrix resets automatically and returns to normal operation without waiting for a reset.
