1. Monitor use
MVC-6850 is a monitor with receiver operating in DUPLEX system  it is not required to
press any pushbuttons to carry on the conversation.
Monitor MVC-6850 is dedicated to digital entry phone systems produced by Laskomex
(CD-2501, CD-2502 and CD-3100). It also co-operates with floor panels with color camera
which work in Commax analog system.
A colour camera can be used alternatively with floor panel; its power demand should not
exceed 250mA at supply voltage 12V DC (CAM2).
Monitor can control gate drive by short circuit the external terminal to the ground.
2. Installation of monitor
Monitor should be installed inside the building at a height ensuring comfortable use by all
users. In a place where the monitor will be installed a metal frame should be mounted by
means of strut pegs and screws (elements delivered with standard equipment).
Connecting wires should be routed through a cutout in the mounting frame center. Then
wires should be connected to appropriate terminals in the backside of monitor.
Finally, the monitor should be hung on the frame and pulled downwards to protect it against
falling down.
Monitor should be connected with power supply cut off!
Prior to monitor hanging the number should be programmed  description below in item
4.
Monitor can be supplied directly from individual power supply adaptor 13,5V DC/1A (dwg.5)
or from video signal distributor CVR-2 to which central feeder is connected 15V DC/4A
(dwg.4).
Central feeder enables supplying distributor CVR-2 and 4 monitors connected to its outputs.
Lengths and diameters of wires between distributor CVR-2 and monitor supplied centrally
are shown in table 1. At a distance longer than 30m individual monitor power supply
adaptors should be used. Then the requirements applying to audio and video line wires
given in service instruction for CD system should be met.
It is recommended to use spiral wires UTP cat.5.
Table1 Minimal wires diameters depending on distance between
CVR-2 and monitor supplied centrally
Diagram showing connection of the monitor to CD system and floor panel (or alternatively
colour camera) is presented in dwg. 4 and 5, location of function pushbuttons - in fig. 1
and arrangement of receptacles and monitor control elements - in dwg.2.

Service of installation procedure (requires activation in CD system)
During activated monitoring from the camera of CD system and hung up receiver we
should press quickly five times pushbutton CONTROL (signalling diode will light also in
red) and then pick up the receiver and press pushbutton LOCK. Electronic cassette of
CD system will search monitor  after founding it monitor number will be reproduced
in the loudspeaker. Sound signals will be generated according to the number of hundreds,
tens and unities of the programmed number. Longer break means passing to next digit
in the programmed number and longer duration of sound signal means zero value of
a given digit.
If pushbutton LOCK is not pressed within 30 sec the procedure will be stopped automatically.
After finishing of number reconstruction it is possible to select calling signal for this
monitor by sequential pressing pushbutton LOCK; short press of receiver`s hook causes
changing calling volume. Four volume modes are possible: quiet, intermediate, loud and
increasing (three short signals of increasing frequency).
After having made the changes the receiver should be hung up, then the centre will call
back to monitor and the fitter will be able to check the functioning of acoustic track and
electro-catch.
3. Gate drive control
Pressing a PROG button causes a short circuit terminal BR to the GND.
Two modes of gate drive control are possible - only during conversation and with receiver
picked up. To change this mode pushbutton PROG (backside of monitor) should be
pressed during pushbutton CONTROL pressed and the receiver hung up. Another
pushbutton PROG keystroke switches mode. Actual mode is signalled by signalling diode
- green color means gate drive control during conversation and red color means gate
drive control with receiver picked up. Gate drive control during conversation is default
mode.
It is recommended itself use relay to control any external device. To secure relay against
supertension polarized diode should be connected parallel to coil of repeater (see dwg. 4).
CAUTION!!
To terminal BR don't connect any source of voltage!
4. Monitor programming
In standard delivery in each monitor number 63 is programmed. This is a test number
and even in apartment 63 it should be programmed again.
Programming should be done directly after monitor connection and before its mounting.

Programming should be done when monitor power supply is on.
Note!
In the monitor apartment numbers within a range 1...255 can be programmed. Programming
a number bigger than 255 is not possible. Number 0 should not be programmed!
Each such attempt will cause programming of default number 63.
Programming is done by means of pushbuttons: PROG (in the monitor rear part), LOCK
and CONTROL as well as two colour LED.
Functions of pushbuttons during programming monitor number:
PROG - entering programming mode
CONTROL - entering programmed value
LOCK - confirmation of entered value, passing to next programming
stage
Arrangement of pushbuttons and signalling diode is shown on dwg. 1 and 2.
Programming new number requires the following activities:
4.1. We should press three times pushbutton PROG on a plate in the monitor rear part
(see dwg.2)  this should be done within 3 sec. Monitor passes to programming
mode which is siganalled by a short flash of LED diode.
4.2. Setting number of hundreds. Pushbutton CONTROL should be pressed as many
times as there are hundreds in the programmed number (0,1 or 2). Each pressing
is signalled by green flashing of LED diode. Then entering number of hundreds
should be finished by pressing pushbutton LOCK which will be confirmed by longer
flashing of a diode. If the number of hundreds is equal to 0 (programmed number
smaller than 100) pushbutton LOCK should be pressed immediately and the next
step should be realized  entering the number of tens.
4.3. Setting number of tens. Pushbutton CONTROL should be pressed as many times
as there are tens in the programmed number (0,1 or 2). Each pressing is signalled
by green flashing of LED diode. Then entering number of tens should be finished by
pressing pushbutton LOCK which will be confirmed by longer flashing of a diode. If
the number of tens is equal to 0 pushbutton LOCK should be pressed immediately
and the next step should be realized  entering the number of unities.
4.4. Setting number of unities. Pushbutton CONTROL should be pressed as many times
as there are unities in the programmed number. Each pressing is signalled by green
flashing of LED diode. Then entering number of unities should be finished by pressing
pushbutton LOCK which will be confirmed by longer flashing of a diode. If the number
of unities is equal to 0 pushbutton LOCK should be pressed immediately.
4.5. Finishing the programming procedure. Checking the number.
Green diode starts flashing as many times as there are hundreds, tens and unities
in the programmed number. Longer break means passing to next digit in the
programmed number while longer flashing of red diode means a zero value of
a given digit. After finishing reproducing the programmed number the diode will light
at the same time in two colours, then one colour will extinguish and the colour of
a diode will correspond to volume level of acoustic signal before starting the
programming procedure.

4.6. If the number is not programmed within 30 sec the procedure will be stopped automatically
and monitor number will not be changed.
5. Checking the monitor number
To check the monitor programmed number pushbutton LOCK should be pressed and holded
in waiting mode (no audio or video connection) and with receiver hung up. A diode will light
in colour comforms to gate drive control mode, next it will light for a moment in both colours
and then the programmed number will be reproduced according to item 4.5.
6. Configuration of video line
Depending on the topology of video signal transmission system there are available three
set-ups of video line configurations. This is done by means of jumpers available in the cut-
out in the rear part of monitor casing (see dwg. 2 or sticker on the monitor rear part).
- BNC - set the jumper in this position if video signal is sent by a concentric cable.
- UTP - set the jumper in this position if video signal is sent by UTP spiral cable.
- UTP+TERMINATOR - set the jumper in this position if video signal is sent by UTP spiral
cable and the monitor is located at the end of video bus bar or is the only line load.
7. Monitor control
Monitor is equipped with three step control of acoustic signals (calling from external panel,
calling from floor panel, door bell), colour saturation, contrast and picture brightness.
Three pushbuttons on the right side of monitor are used for step control of contrast, saturation
and brightness.
Volume of acoustic signalization can be changed by switch on the right side of monitor.
Upper position means loud signal, middle position  quiet and lower position means switched
off signalling which is also signaling by red color of signalling diode.
Note!
In special cases audio signal can be corrected by means of the following potentiometers
available after the monitor rear casing has been taken off:
- SPK1 - correction of loudness level of a signal coming from external panel
- MIC1 - correction of loudness level of a signal going to external panel
- SPK2 - correction of loudness level of a signal coming from floor panel
- MIC2 - correction of loudness level of a signal going to floor panel
