Teleprinter Secure InterfaceMounted under the TTY keyboard, this unitprovides remote selection of secure or clear TTYoperation. By placing the red guarded TTY/TPR switchto the BYPASS position, the operator closes a relay tobypass the TSEC/KW-7.Communications Interface No. 1Figure 1-22.-COMM interface No. 1.over voice radio. Switches on the front of the boxprovide control over data conversion,TSEC/KW-7 Security UnitThis unit provides encryption and decryption of thebaudot code. It is usedoperation.whenever the teletype is inTSEC/KWX-7 securityUnit (RCU)Unit Remote ControlThis unit is located next to the TTY keyboard andenables the operator to control the TSEC/KW-7 withouthaving to leave his/her seat.This unit (fig. 1-22) connects the TTY system withthe central computer. It converts the baudot code into30-bit, parallel, binary computer language. The switchesand controls on the front of the interface are inoperativein the OPERATE mode.TELETYPE SYSTEM OPERATIONFigure 1-23 shows the teletype system blockdiagram.Off-line operation of the TTY system requires theoperator to select an appropriate frequency on the HF-1,HF-2, or UHF-2 control panel and to select TTY modeon the communications selector panel. The selectedradio is automatically mode forced into a datatransmission mode. The operator selects words perminute (WPM) speed (normally 100) and TTY on theHSP, and DIR SEND on the TTY keyboard. Phasing theTSEC/KW-7 sends a synchronization signal that isreceived by all other units on the frequency. Once allunits are synchronized, they are ready to accept data.When a key is depressed on the TTY keyboard, thecorresponding baudot code is generated. This is sent toFigure 1-23.-Teletype system block diagram.1-24
the signal data converter, where it is converted to audiotones and then transmitted out over the selected radio.When the message is complete, REC (receive) isselected on the keyboard. This selection allows thesystem to receive phase tones and incoming messagesfrom other stations on the frequency.The on-line mode is designed to simplify the workof the operator. Actual system operation is covered invarious software publications. In general, the operatortypes an outgoing message in the central computer. Theoperator performs all the operations described above,except XMIT is selected on the TTY keyboard.Depression of the XMIT switch on the keyboard directsthe central computer to send the stored message throughCommunications Interface No. 1 into the TTY system.In the same manner, when REC is selected on thekeyboard and CMPTR selected on the HSP, anyincoming messages are sent to the central computer.Currently, the computer has the ability to store onemessage of approximately 800 characters for review bythe operator.In addition to teletype data, the TTY system cansend and receive data to and from the central computer.In input data, the operator simply selects CONST &EDIT on the keyboard. Any keyboard depressions arethen sent to the central computer via thecommunications interface.To produce hardcopy of computer data, CMPTR isselected on the HSP. Software functions then allow thecentral computer to print data on the HSP viaCommunications Interface No. 1. This data is sent at3,000 words per minute regardless of the WPM SPEEDswitch on the HSP.Q1.Q2.Q3.Q4.Q5.Q6.Q7.Q8.Q9.Q10.Q11.Q12.Q13.REVIEW QUESTIONSWhat is the most important means of communicatingin the Navy today?What frequencies are included in the superhigh-frequency band?How many LS-602/AI panels are there in atypical aircraft?What type of encoding/decoding is used in theICCG system?What is the actual frequency range of theAN/ARC-197 radio set?How many preset channels are available with theAN/ARC-187 radio set?What fault is indicated when the fault indicatoron the C-11950/ARC-187 control box flashes ata slow rate?The HF-2 long-wire antenna has degradedoperation at which frequencies?What is the purpose of the lightning arrester usedin the HF system?What radio sets can be used with the data linksystem?Who has primary responsibility for the hardwaresetup of the data link system?Which unit in the TTY system provides theinterface with the radios?Which unit connects the TTY system with thecentral computer?1-25
