4 Matrix op erating features
4.1 Video inp ut 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:

4.1.2 Day and nig ht 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 sele ction
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.
Keyboard MTC-1 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 In c/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 vide o dedicated to the VCR
Output video n°4 of matrices EKR-8/4 and EKR-16/4 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.
