PREFACE
The TSA 082N is a high quality microprocessor
based video switcher which is suitable to
connect up to eight cameras or other video
sources. Two independent outputs allow to
connect the main monitor and the video tape
recorder with optional clock output. Alarm input
is suitable to connect eight alarm sensors. On-
screen display function allows higher operational
efficiency.
Standard BNC-type input and output connectors
enables the TSA 082N to be used with other
CCTV switchers, cameras, monitors and video
tape recorders.

CONTROLS AND CONNECTORS
FRONT PANEL
51 2 3 4
(1) CH B - TIME
LED display to show the sequence of
the CHANNEL B or the sequential time of the
CHANNEL A.
When the VCR CLOCK is selected the display
shows C. When the frame-by-frame mode is
selected the display shows F. When one of the
TIME keys is pressed a decimal point lights and
the display shows the selected sequential time -
0 for 1 to 9 seconds, 1 for 10 to 19 seconds etc.
When an alarm occurs and the CHANNEL B is
selected the decimal point blinks.
(2) MODE - ALARM STOP
Key to select operating mode - auto (sequential)
or manual - or to reset the alarm.
(3) TIME
Keys to adjust the sequential time from 1 to 90
seconds.
(4) CHANNEL A
Keys to select the input signals in manual mode
or to eliminate the inputs in auto (sequential)
mode.
In manual mode red LED lights at selected input,
in auto (sequential) mode red+green LED lights
at selected input. If all the inputs are eliminated,
the switcher automatically switches the first
input.
(5) POWER
Switch to turn the power on / off - lights in the
power on position.

(2) CH A
BNC video output connector of the CHANNEL A.
It is suitable to connect the main monitor. On-
screen display shows the number of selected
input and sequential time adjusting.
(3) CH B
BNC video output connector of the CHANNEL B.
It is suitable to connect the video tape recorder
optionally with CLOCK output.
(4) ALARM IN
Alarm input / remote control connector (D-9F). It
allows to connect up to eight alarm sensors.
When the remote control possibility is used all
the alarm inputs are inactive.
(5) CLK
VCR-CLOCK input connector (terminal block).
When the video tape recorder with CLOCK
output is used and connected to the VCR-CLK
input, the sequence of the CHANNEL B will
depend on the CLOCK pulse. In the SET-UP,
VCR-CLOCK input has to be selected.
(6) ALM
Alarm output connector (terminal block), open
collector output. It is suitable to connect the
video tape recorder with alarm input.
(7) VIDEO IN

ALARM / REMOTE CONTROL CONNECTION
Connection diagram:
Notes:
•Negative triggering - all alarm switches must
be opened, in case of alarm they are closed.
•Positive triggering - all alarm switches must be
closed, in case of alarm they are opened.
Notes:
•T1 - start/stop key
•T2 - manual scan key
VCR-CLOCK CONNECTION
The VCR-CLK input is a standard TTL negative
triggered input (5V to 0V)
Note:
•If the VCR CLOCK pulse is 12V, set the
jumper J2 to 12V position.
VERTICAL INTERVAL
SWITCHING
This unit includes an electronic circuit which
allows smooth switchings without picture roll or
flutter. When the cameras and this unit are line-
locked this function appears. Line-lock phase is
adjustable in ±127 steps. (±2.2 ms)
ALARM SPECIFICATION
When only one alarm input is activated, the
alarmed video input appears on the CHANNEL
A or CHANNEL B. On the CHANNEL A the
"ALARM" message is on the screen. Buzzer is
activated. On the CHANNEL A auto and manual
LEDs blink. When the CHANNEL B is selected
the decimal point on the LED display blinks.
Alarm output is activated (switched to the
ground). When more then one alarm input is
activated, the alarmed video inputs appear on
the CHANNEL A or CHANNEL B sequentially.
The CHANNEL B is automatically switched from
sequential mode to frame-by-frame mode when
the ALARM FRAME SWITCHING is enabled.
This function is disabled when the VCR CLOCK
is selected.
Alarm sequential time and alarm duration time
are adjusted in the SET-UP. With pressing the
key ALARM STOP manual reset of alarm is
achieved on the CHANNEL A.
REMOTE CONTROL
Remote control possibility on the CHANNEL A
appears when the auto (sequential) mode is
selected. Key T1 is used to stop and start the
auto sequence. When it is stopped key T2 is
used for manual scan. In the set-up, REMOTE
CONTROL has to be selected.
ON-SCREEN DISPLAY
For enhanced operational efficiency, the
TSA 082N has an multi-language on-screen
display function on the CHANNEL A in English,
Italian and German language. The characters
are displayed as white characters with black
edging, thus allowing easy reading against any
contrast background. The number of input is
displayed in the right corner and the sequential
time in the left corner below.
