Code of the device (figure 1) works as follows.

Before you begin code device is connected to a control device (not shown). Then, the control unit through the connector 1 on block 2 protection circuits command is issued in the form of a DC voltage, which triggers the Executive contacts 6.4-6.9 block 2 protection circuits, connecting to connector 1 input and two output unit 3 mates, as well as input "write (erase)" (not labeled) of the memory block 5. The information is exchanged through the block 3 mates and the connector 1 on the two-wire line (not shown) duplex exchange of commands with the following format: opcode, name operand, the dimension of the data. The opcode specifies the type of the command being executed. The name operand is designed to search operand, which is the action dimension is to determine its size. The operand is located in memory block 5 has the following format: the name of the operand, the dimension and the data operand, i.e. in block 5 of the first memory and is the name of the operand, then the dimension, and then the data.

After connecting these circuits to the connector 1 from the control unit in the control unit 4 receives the command selection module, which is produced by the search module b is the eye 5 of the memory. When this module from the device control command is sent to the comparison which is search code protection block 5 memory. The security code is read in the control unit 4, where it is compared with the data received in the team comparison. In case of equality unit 4 control permits operation with this module. The control unit works in conjunction with code device. To check for code device control device during operation carries out the control ID (signs) code of the device. ID made in the form of jumpers set of chains. The control ID is generated using a read command. If necessary, the security code module in block 5 of the memory can be changed. For this purpose the control unit 4 receives the write command data corresponding to the new code security module. At this command, the control unit 4 generates data and control signals on the outputs of the block 5 memory and makes a request to the control device (transmits a single pulse) on the formation of the recording signal. The control unit generates a recording signal, which is supplied to the corresponding input unit 5 memory. After recording a new security code module, the control unit 4 transmits the device control command about okoncane the record, and the control unit transmits to the control unit 4 a diff with the new security code module. At this command, the control unit 4 compares the new code protection read from unit 5 memory with data received in the team comparison. In case of positive result of the destruction of the old security code module by programming each bit of the code protection level logical units to logic level zero.
