The video signal from the KT-257 TV-camera comes to connector X1 of the device

and then – to the input of the ЭМ-1205-1 videoswitch module. The ЭМ-1205-1 videoswitch

module contains a DAC, an ADC and a PLIC. The ADC performs conversion of the analog

video signal into a digital one. Then, the PLIC provides writing of the data into the internal

RAM and reading the content of the RAM in an inverse order thereby performing the image

rotation required. The rotation process is initiated on a remote control command. From the

output of the PLIC the digital data come to the DAC that does the conversion into an analog

output video signal.

The ЭМ-1204-1 videoswitch module performs multiplexing of 21 input video signals to

five outputs in accordance with remote control commands that come from the ЭМ-1209-1

controller via RCLI lines.

The ЭМ-1204-1 videoswitch module contains an analog matrix multiplexer providing

commutation of 24 input signals to 6 outputs. The device employs only 21 inputs and five

outputs. The matrix multiplexer is driven by a built-in microcontroller (MC) receiving

commands from the ЭМ-1209-1 controller.

The video signal from the output of the ЭМ-1205-1 videoswitch module comes to input

1 of the ЭМ-1204-1 videoswitch module. The signals from the TVDs of the TV-complex are

connected to inputs 2 to 20. "Video Input 21" of the ЭМ-1204-1 videoswitch module is

reserved and not used in the TV-complex. The output video signals of the ЭМ-1204-1

videoswitch module are assigned as follows:

"Video Output 1" via connector X22 of the device comes to TVM ВС-2-1 No.1 of the

TV-complex (first CP of TV-complex);

"Video Output 2" via connector X23 of the device comes to TVM ВС-2-1 No.2 of the

TV-complex (second CP of TV-complex);

"Video Output 3" via connector X24 of the device comes to the ВС-1-1 No.1 of the TV-

complex (third CP of the TV-complex);

"Video Output 4" comes to connector X25 of the device and is not used in the TV-

complex;

"Video Output 5" comes to the video input of the ЭМ-1211 diagnostics module and

then - to the ВС-2 TVM.

The ЭМ-1211 diagnostics module performs switching between video signals for the

ВС-2 TVM coming from the ЭМ-1204-1 videoswitch module and a diagnostics signal that is

generated by the ЭМ-1211 diagnostics module by itself.

Commutation of video signals is done by pressing the buttons on the front panel of the

ЭМ-1211 diagnostics module. By pressing button SELECT the video signal from the

ЭМ-1204-1 videoswitch module (from the TVD chosen on the ЭМ-1212-1 control module) is

connected to the ВС-2 TVM. Pressing button ENTER provides connection of the video signal

formed in the ЭМ-1211 diagnostics module, containing data on the TV-complex state, to the

screen of the ВС-2 TVM.

The main unit of the genlocking system is the EM-1209-1 controller. The PLIC of the

unit forms the DGP signal basing on clock pulses of a quartz oscillator and supplies it to the

six DGP outputs via a buffer amplifier. This signals are fed to connectors X26-X31 of the

device and finally arrive to the TM-1304 combined modules. One DGP output (connector

X31) is reserved and not used in the TV complex.

1.1.4.3 Control System

The functional control system (CS) is formed by the ЭM-1209-1 controller (A33) along

with microcontrollers and microprocessors of the main device modules interconnected via

RCLI lines. The ЭM-1209-1 controller constitutes a dedicated computer performing the main

control functions of the TV complex. The microcontrollers and microprocessors that are parts

of the ЭM-1204-1 videoswitch module (А31), ЭМ-1211 diagnostics module (А21), ЭM-1212-1

control module (А22), and ЭM-1242 interface unit (А23) perform local control functions.

The control system provides:

- communication with the TM-1215-4 control modules and the TM-1230 control module

of the TV complex CPs to receive control instructions from the module buttons;

- input of control instructions from the ЭM-1212-1 control module, that is a part of the

device, during the TV complex operation check.

- processing of control instructions and output of instructions to the execution units of

the device and other modules of the TV complex to provide power supply and control of the

TVDs, correction and commutation of video signals, centralized genlocking and video

recording.

- receiving and analysis of replies of execution units and indication of instruction

fulfillment results;

- preparation and output of data about the state of the TV-complex to the automatic

checkout system (ACS).

The ЭM-1209-1 controller is the main control element of both the device control

system and the whole TV complex. The working software of the controller is written to ROM

and provides control of the TV complex via serial duplex communication channels. The

ЭM-1209-1 controller incorporates a power supply supervisor and a watchdog timer,

controlling the working program execution and automatically resetting the system in case of a

fault. The ЭM-1209-1 controller provides 14 serial duplex interface channels (RCLI) and an

RS-232 channel. The working program can be reset by pressing the RESTART button,

mounted on the front panel of the controller. The ЭM-1209-1 controller is installed on the third

floor of the device in the rightmost row (see Appendix B, pos.13). To the left of that the two

ЭM-1209-1 controllers of the BSP are installed.

The modules that are parts of the device as well as other modules included by the

TV-complex are controlled via RCLI channels.

The RCLI channels have the following parameters:

1.1.4.2 Genlocking System

- loop-type channel, duplex, four-wire, two wires are used for output datastreams (data

transmission lines) and two wires are used for input datastreams (data reception lines);

- data transmission and reception circuits are galvanically decoupled;

- baud rate - 19200;

The genlocking system provides centralized synchronization of all the TVDs of the

complex by forming DGP signals on the six output connectors of the device. The DGP signal

constitutes a pulse sequence with a swing of 3 V, frequency of 15625 Hz and duration of

5 µS. Every 625-th pulse has a duration of 12 µS. The centralized synchronization reduces

the mutual interference level and simplifies video signal processing.

- number of data bits - 8;

- number of stop bits – 1;

- LSB is transferred first;

- pause, stop bit and logic one are transferred as current from 0 to 1 mA;

- start bit and logic 0 are transferred as current from 15 to 25 mA;

Functioning of the ЭМ-1212-1 control module as a part of the control system is

provided by microcontroller CS, PLIC, interface and buttons with LEDs. The microcontroller

(MC) together with the PLIC inquires the buttons. On request from the ЭМ-1209-1 controller

the MC forms a reply array with the codes of the buttons pressed and transfers it via the

RCLI channel to the ЭМ-1209-1 controller.

The MC of CS receives from the ЭМ-1209-1 controller a command array with

instructions for lighting up the LEDs and switches on the corresponding LEDs by means of

the PLIC. The working program of the ЭМ-1209-1 controller analyses the button state and

decides whether to light up the LEDs.

The ЭМ-1211 diagnostics module constitutes a special computer whose working

software is written into the ROM by Manufacturer. It has a built in power supply supervisor

and a watchdog timer automatically controlling the working program execution and resetting

the system in case of a fault. The ЭМ-1211 diagnostics module includes a video adapter

forming the video signal and a switch connecting either the external signal or the adapter

signal to the common output. The 55-channel ADC measures the incoming d.c. voltages from

minus 30 to plus 30 V with a ratio error of no more than 0,2%. The ЭМ-1211 diagnostics

module has an RS-232 and a RCLI interface channels. There are five buttons and one LED

on the front panel of the ЭМ-1211 diagnostics module (Fig.2). The LED indicates a fault in

the TV-complex. Button ENTER outputs the ACS frame No.1 on the ВС-2 TVM screen. The

arrow buttons allow switching between frames of the ACS. Button SELECT switches the

video signal from the ЭМ-1204-1 videoswitch module to the screen of the ВС-2 TVM. Button

RESTART forces reset of the working program. The ЭМ-1211 diagnostics module is installed

on the second floor of the device in the leftmost row (Fig. B1, pos.3).

The ЭМ-1209-1 controller allows to take a TVD out of servicing only from the

ЭМ-1212-1 control module panel.

ТМ–1104–3

Via a RCLI channel the diagnostics module receives data from the ЭМ-1209-1

controller on the state of the TV-complex units and modules. This information is prepared

during data exchanges via the RCLI channels and contains data on the presence of feeding

voltages and video signals, character of data exchanges between different modules of the

TV-complex, state of the TVDs, VRDs and the ТМ-1215-4 control modules. The ЭМ-1211

diagnostics module transfers data for light indication of faulty units and modules to the

ЭМ-1212-1 control module via a separate RCLI channel.

The ЭМ-1212-1 control module forms three video frames of the ACS for indication of

the TV-complex state on the screen of the ВС-2 TVM.

The ACS frame No.1, "STATE OF МТК-110МЭ" (Fig.3), is formed on pressing button

ENTER. In this frame enabled modules and units are shown as their codes against a light

background, disabled – as theirs codes against a dark background and faulty ones – as their

codes against a blinking background.

Fig. 5 – ACS Frame No.3 "MODULE FEEDING VOLTAGES".

---

POD 108FR

The feeding voltages are symbolically shown as horizontal lines with four marks. The

leftmost mark represents the zero point. The next three marks represent the minimum,

nominal and maximum values of the voltage. The length of a line denotes the voltage in a

non-linear scale. The position of the minimum mark corresponds to 95% of the rated voltage.

The position of the rightmost mark corresponds to 105% of the rated voltage. If the voltage

controlled falls out of the tolerance limits, the line blinks that is a sign of a fault in the module.

The output voltages of the three ЭМ-1213 power supply units are displayed in the upper part

of the frame. The supply voltages produced by power supply cells in the corresponding

modules are displayed below. The number of ACS frame No.3 is shown in the right lower

corner.

Fig.4 –ACS Frame No.2 "STATE OF МТК-110МЭ TVDs".

The "ON" column contains the numbers of the CPs, from which the TVDs were

switched on. If the same TVD was switched on from several CPs, their numbers are

displayed via blanks. The device including the ЭМ-1212-1 control module and the ВС-2 TVM

is designated as CP No.4 of the TV-complex. The "CTRL" column shows the number of a CP

of the TV-complex and the remote control command being executed from this CP.

The "CHECK" column shows the number of CP of the TV-complex from which the

TVD was chosen for servicing.

Frames are switched over by pressing the arrow buttons on the front panel of the

ЭМ-1211 diagnostics module (Fig.2).

The ЭМ-1212-1 control module indicates faulty modules of the TV-complex with the

LEDs, in accordance with the information received from the ЭМ-1211 diagnostics module via

the RCLI channel. Light-up of the LED of the МТК-110МЭ indicates a fault in some unit or

module not represented on the ЭМ-1212-1 control module front panel. To get more specific

information about the faulty module, the ACS frame No.1 should be output on the TVM

screen.

The number of ACS frame No.2 is shown in the right lower corner.

The ACS frame No.3, "MODULE FEEDING VOLTAGES" is shown in Fig.5.

Light-up of one of the LEDs on the ТМ-1304 No.1 – ТМ-1304 No.5 combined modules

on the ЭМ-1212-1 control module front panel means that either one of the modules

comprised by the ТМ-1304 combined module is malfunctioning or the TVD working with this

combined module is out of order. To localize the faulty module, the ACS frame No.1 should

be output on the TWM screen.

Light-up of the FUSE diode on the front panel of the ЭМ-1212-1 control module means

that one of fuses F1-F16 installed on the fifth floor of the device is blown out. To localize the

faulty fuse, the ACS frame No.1 should be output on the TVM screen.

Information acquisition and control of the indication LEDs of the ЭМ-1212-1 control

module is performed by the microcontroller and PLIC of the ACS. The ЭМ-1212-1 control

module is installed in the middle of the second floor of the device. The device door has a

glassy window opposite to the ЭМ-1212-1 control module thereby allowing observation on

the state of the TV-complex when the door is closed.

The three-phase feeding voltage 220 V, 50 Hz from the ЩР-03 switchboard is

supplied to the device via a cable through connector XP1 and the assembly unit (A1). The

device is switched on with toggle switch POWER. The three-phase voltage form the switch

arrives to the indicator lamps through the three fuses and then - to PCB XT1 of the assembly

unit. The switch and the fuses are found under the drop cover on the assembly unit front

panel. The lamps indicating presence of feeding voltage 220 V,50 Hz are mounted on the

assembly unit front panel.

The three-phase feeding voltage 220 V, 50 Hz from assembly unit PCB XT1 through

PCB XT1 of the device is supplied to the ФСП-3В interference rejection filters (A2 - A7) and

then – to the ЭМ-1213 power supply units (A61, A71, A72). The ЭМ-1213 power supply units

are connected to different phases of the three-phase mains.

Each of the ЭМ-1213 power supply units has six galvanically decoupled d.c. outputs

with the following parameters:

- one 27 V output with a current of up to 4 A;

- one 27 V output with a current of up to 2 A;

- four 6 V outputs with a current of up to 2 A.

1.1.4.5 Chronometrical Information Input System

All the d.c. power supplies in the ЭМ-1213 power supply units have overcurrent and

short-circuit protections that are automatically reset when the overload conditions are

removed.

The 6 V supply voltages produced by the ЭМ-1213 power supply units are used for

feeding the modules of the device. The feeding voltage of plus 6 V is provided by connecting

the negative terminals of the 6 V power supply units to the common bus, whereas for

obtaining a feeding voltage of minus 6 V the plus 6 V power supply units are connected vice

versa. The 6 V supply voltages are supplied to the device modules through PСB AP2 of the

device.

All the device modules that are supplied with the plus 6 V and minus 6 V voltages are

fed from two or three ЭМ-1213 power supply units simultaneously. This ensures operability of

the device in case of failure of one of the ЭМ-1213 power supply units.

The modules consuming the plus 6 V and minus 6 V voltages contain power supply

cells that form their own feeding voltages, provided at least one of the ЭМ-1213 power supply

unit voltages is present. The internal supply voltages of the consuming modules are

connected to the ЭМ-1211 diagnostics module inputs for control.

The BC-2 TVM is fed from the ЭМ-1213 power supply unit (A72) with the plus 27 V

voltage. The ЭМ-1239 power supply installed into the BC-2 TVM produces its own supply

voltages of plus 12 V and plus 5 V.

The chronometrical information input system receives chronometrical data via

separate serial channels from device "Гном-2МЭ", transmits it to the external ТМ-1213

terminal module for mixing into the video signal during video recording and displays this data

on the screen of the ВС-2 TVM.

The main unit of the chronometrical information input system is the ЭМ-1242 interface

unit. The signals of the main and reserved channels of device "Гном-2МЭ" are supplied to

the interface unit via connectors Х40 and Х41. The MC and PLIC of the ЭМ-1242 interface

unit perform processing of these signals, reception of the incoming arrays containing

chronometrical information and writing the data to the internal RAM of the PLIC.

On request from the ЭМ-1209-1 controller the MC forms a reply array that is

transferred to the ЭМ-1209-1 controller via a RCLI channel.

The ЭМ-1209-1 controller periodically interrogates the ЭМ-1242 interface unit, forms

data arrays containing date and time and transfers them to the ТМ-1213 terminal module

and ЭМ-1211 diagnostics module. The latter displays the date and the time received

from each of the "Гном-2МЭ" channels in ACS frame No.1. In case of absence of the

information in one of the "Гном-2МЭ" channels, dashes are displayed in ACS frame

No.1.

The plus 27 V voltage from the other outputs of the ЭМ-1213 power supply unit is

distributed among various units and modules of the TV-complex, passing through PCB AP1

and fuses F1-F16 to the output connectors of the device. The fuses protect the power

supplies against short-circuits in each of the loads. The fuses are installed on a panel on the

fifth floor of the device. There is a LED near each of the fuses indicating presence of the plus

27V voltage on the fuse output.

1.1.4.6 Power Supply System

The power supply system provides secondary feeding voltages for the units and

modules incorporated by the device as well as some other units of the TV-complex.

The power supply system comprises the following device modules:

- assemble unit (A1);

The external loads of the plus 27 V supply voltage of the ЭМ-1213 power supply units

are shown in Table 3.

- interference rejection filters, the ФСП-3В (A2 - A7);

- power supply unit, the ЭМ-1213 (A61, A71, A72);

- fuses F1 - F16;

- power supply cells that are parts of the ЭМ-1204-1 and ЭМ-1205-1 videoswitch

modules, ЭМ-1209-1 controller, ЭМ-1211 diagnostics module, ЭМ-1212-1 control module

and ЭМ-1242 interface unit.
