The drawing shows the block diagram of the device .;

The device contains synchronization unit 1, data input unit 2, sensor codes, converter 4 gay codes 5 single impulses, unitary code registers b, control unit 7, single-byte registers 8 numbers, interface 9, first and second distributors 10 and 11 pulses . A switch block is connected to the outputs of the device.

The first input of the distributor 10 pulses is connected to the output of a 4-code converter, and the first output is connected to. the first input of the distributor 11 pulses. The first output of the generator 5 is connected to one of the inputs of the registers b, and the second to the second input of the distributor 10.

The six outputs of the synchronization unit 1 are connected respectively to the inputs of the unit 2, the 4-converter converter by one of the generator inputs 5 single pulses and the control unit 7, the third input of the first distributor 10 pulses, the second input of the second distributor 11 pulses. The outputs of block 9, distributors 11 and 10 pulses are the first, second and third outputs of the device, respectively.

The coordinate field of the block of data entry, made in the form of a tablet, consists of a byte reading zone and a mode setting zone. The byte reading area consists of 256 squares, and the mode setting area is divided into four columns with the names of the operation modes.

The operation of the device nodes is synchronized by a continuously operating synchronization unit 1. Some pulses of synchronization unit 1 can be switched with a coordinate code received from a 4-code converter.

At the beginning of each cycle of the synchronization unit 1, the coding windings of the unit 2 are polled and transformed)) with 1 consecutive sensor codes of the 3 codes to the second binary coordinate code using the 4 code converter.

The setting of the operating modes is made by combining the sensor pointer 3 codes with the center of the square, which shows the name of the operating mode, and then pressing the start button connected to the input of the generator 5.

This starts the operation of the generator 5 single pulses and records the coordinate code from the output of the converter 4 codes to registers 6. At the outputs of register 6, a unitary code is presented, represented by a unit in only one of the bits and corresponding to a particular mode of operation.

To write bytes in registers 8 IJ; use the Input mode 1 and Input 2 modes

After setting the byte input mode, the operator performs an orderly reading of the bytes using the input card superimposed on the bytes read field of Tablet 2.

The transfer of information to an interfaced device (not shown in the drawing) occurs via a T5lock 9 interface or block 12 of switches. Block 9 of the interface works when setting the operation modes for the transfer of commands / Control-Write, Control Count, and others according to the rules of the standard selector channel. Through interface block 9, information bytes and corresponding control signals are transmitted or received. The end of the transmission or reception of bytes is determined by the control unit 7.

The operation of the device in the mode of information transmission through the block 12 of the switch is as follows.

When this mode is set, a corresponding coordinate code arrives at the first input of the nepBOfo distributor 10 pulses, allowing the start of the distributor 10 pulses at the moment it arrives at its second and third inputs of the signals, respectively, from the output of the generator 5 single pulses and the output of the synchronization unit. The first pulse distributor 10 generates from the beginning a burst of impulses for the interfaced device, and then, after starting the second pulse distributor 11, the pulses are automatically returned to the initial state. The second dispenser 11 pulses works many times. During the kykdy period of his work, eight pulses are successively generated. The time shift between these pulses depends on the frequency of the clock pulses produced permanently at one of the outputs of the synchronization unit 1. The signals from the outputs of the second distributor 11 pulses are fed to the control inputs of all the switches of the unit. 12.

Each switch unit 12 converts a parallel code coming from any two registers 8 into a serial code in the form of tetrads. The tetrads can be interleaved. After transferring a certain number of tetrads with each Kot-wyratora of the block 12, the second distributor 11 D1 pulses under the influence of pulses at the output of the block 1 synchronous | 1 st pregrgitsaet work.

Introduction to the proposed device of distributors 10 and 11 pulses increases its speed, expands national capabilities without increasing the number of input and control units.
