1. FEATURES & PRECAUTIONS

1-1 Features

1. Communications Terminal

As a result of the most up-to-date microprocessor technology, just one piece of equipment can

accomplish complete automatic send/receive of Morse code (CW), Baudot code (RTTY) and AS-

CII code (RTTY & KCS). By using a light pen, it can also handle send/receive of graphic pat-

terns and characters freely.

2. Word Processor Function

Helps with easy generation of documents or letters. With cassette tape recorder storage, the

document can be stored and modified.

3. Selective Calling System

With a eyboard command, SELCAL mode becomes active. Upon receipt of the signal corre-

sponding to your own "SELCAL Characters" (stored in CMOS-Battery-Bac -Up memory), the Θ-

9000E begins to receive the message. And your own "End of Text" will terminate the reception.

Also capable of calling up the specified distant station.

4. Two Display Format and Large Capacity Display Memory

Provides two different display format: 80 characters × 24 lines and 40 characters × 24 lines.

Manually changeable with the eyboard command. Display memory covers up to 14,000 char-

acters. The scroll feature enables to display of all the characters.

5. Graphic Function

Using the accessory light pen, graphic pattern can be drawn on the screen and easily transmit-

ted and received.

6. Full Duplex Function

You may select full duplex mode when the Θ-9000E is used for ASCII mode. Capable of using

as CRT terminal by RS232C serial interface. You can handle up to 9600 baud in send/receive.

7. Built-in Demodulator for High Performance

Three-step shift selects either 170 Hz, 425 Hz or 850 Hz shift with a manual fine tune control

of the space channel for odd shifts. HIGH (Mar Frequency 2125 Hz) / LOW (Mar Frequency

1275 Hz) tone pairs available. Mar only or Space only copy capability for selective fading.

8. Crystal Controlled AFSK Modulator

A transceiver without direct FSK inputs can transmit in RTTY mode by utilizing the high stability

crystal-controlled modulator, controlled by the microprocessor.

9. Optoisolator CW, FSK eyer built in

Very high-voltage, high-current optoisolator eyer is provided for CW, FSK eying.

10. Automatic Transmit/Receive

The transmit/receive switch is controlled by the microprocessor. Built-in remote control ey

function automatically controls the transmit/receive circuitry of the transceiver. manual opera-

tion is also available.

11. Convenient ASCII Key Arrangement

The eyboard layout is ASCII arrangement with function eys. Automatic insertion of LTR/FIG

code.

12. Two Modes in ASCII

In ASCII, both KCS (Kansas City Standard) and RTTY mode tone sets are available.

13. Battery-Bac -Up Memory

Data in the battery-bac -up memory, covering 256 characters × 7 channels, is retained even

when the external power source is removed. Channel 6 is divided into 16 subsections contain-

ing 32 characters, any of which may be used individually. Messages can be repeated 1–9 times

from a eyboard command and any channel can read out continuously. You can store mes-

sages into any channel while receiving.

14. Anti-Noise Circuit

Well designed anti-noise circuit prevents garbled message in the absence of signal.

15. Screen Display Type-Ahead Buffer Memory

A 3120-character-buffer-memory is displayed on the lower part on the screen. The characters

move to the left erasing one by one as soon as they are transmitted. The operator is free to

prepare messages while another document is received.

16. Function Display System

Each parameter of operation (mode, channel number, speed and so on) is displayed on the

screen.

17. "SEND" Function

Allows to send the transmitted text displayed on the screen, including the data stored in every

channel of the Battery-bac -up memory with an instruction from the eyboard. It is possible to

interrupt the transmission and resume it.

18. Split Screen

With a eyboard command, the same screen format can be divided in two; the upper half for

receive and the lower for transmit, While receiving, you can compose text for transmission in

the Buffer Memory with the Pre-load function, which is to be ta en over by the SEND function.

19. Composite Video Signal Output

Composite Video Signal Output is provided for Video monitor display.

20. Printer Interface

Centronics Parallel Compatible interface enables easy connection of a low-cost dot-matrix print-

er for hard copies.

21. Wide range of transmitting and receiving speeds

communication speeds with Fine Adjustments for transmitting and receiving in Baudot and AS-

CII. The multiple speed feature ma es the Θ-9000E ideal for amateur, business and commer-

cial use.

22. Pre-load function

The Buffer Memory can store the messages written from the eyboard instead of sending them

immediately. The stored messages can then be sent with a eyboard command.

23. "RUB-OUT" function

You can correct mista es while writing messages in the Buffer Memory and misspellings can be

erased while the information is still in the Buffer Memory.

24. Automatic CR/LF

While transmitting, CR/LF is automatically sent every 64, 72 or 80 characters.

25. WORD MODE operation

Characters can be transmitted in word groupings from the Buffer Memory. Keyboard-Selctable.

26. LINE MODE operation

Characters can be transmitted in line groupings from the Buffer Memory. Keyboard-Selectable.

27. WORD-WRAP-AROUND

In receive mode, WORD-WRAP-AROUND prevents the last word on a line from becoming split

in two and provides you a readable screen.

28. Automatic Idle Signal Insertion

In RTTY mode, idle signal can be automatically inserted in a pause of transmitting.

29. "ECHO" function

With a eyboard instruction, received data can be read and resent at the same time. This func-

tion enables the cassette tape recorder to be used as the bac -up memory and a system can

be created as effective as paper tape storage.

30. Cursor Control function

Full cursor control (up/down-left/right) is available from the eyboard.

31. Test Message function

Two built-in test messages, "RY" and "QBF" are eyboard selectable.

32. CW Identification function

In RTTY (Baudot & ASCII) mode, eyboard-controlled CW identification is available if required.

33. MARK-AND-BREAK (SPACE-AND-BREAK) system

Mar only or Space only copy capability for selective fading.

34. Variable CW weights

For CW transmission, weights (ratio of dot to dash) can be changed within the range of 1:3 to

1:6 in ten steps.

35. Audio Monitor Circuit

A built-in audio monitor circuit with an automatic transmit/receive switch enables chec ing of

the transmitting and receiving states. In receiving mode, it is possible to monitor the output of

the mar channel, the space channel and incoming audio from AGC amplifier prior to the chan-

nel filters.

36. CW practice function

The Θ-9000E reads data from the hand ey and displays the characters on the screen. CW ey-

ing output circuit wor s according to the ey operation.

37. CW Random Generator

Output of random CW signal can be used as CW copy practice.

38. Cross-hatch chec ing output terminal

1-2 Precautions

1. You should plan to read this OPERATOR'S MANUAL thoroughly to become familiar with your Θ-

9000E.

2. Before ma ing connection to a transceiver, practice is recommended with a CRT display.

3. Adjust for minimum SWR between the transceiver and antenna as follows:

OUTPUT SWR

< 10 W Maximum 1.5

10 W ··· 100 W Maximum 1.3

100 W ··· 500 W Maximum 1.1

Table 1 SWR Adjustment

4. Be sure that the connection to the input circuits and output circuits are appropriate. Input sig-

nal and load should be within the range mentioned in the Specifications.

5. Voltage of DC power supply should be within the range of DC 11 V ~ 14 V.

6. DC power supply for the Θ-9000E should not be connected to other equipment if any interac-

tion is noticed.

7. It is suggested that the Θ-9000E is put at a well-ventilated dry place not exposed to the direct

sun with special care for intense heat.

8. Notice the maximum speed as follows:

In full duplex mode, the available speed is up to 9600 baud and in RTTY modem, up to 150

baud. When you connect to the cassette tape recorder in KCS mode, the maximum baud rate

is variable according to its characteristic. In good condition, you can handle up to 1200 baud.

Other modes are usually up o 9600 baud.

9. In order to prevent the possibility of receiver interference from the microprocessor cloc , it is

recommended that the receiving antenna not be adjacent to the Θ-9000E terminal. The trans-

mitting antenna should be well matched and also should not be located adjacent to the termi-

nal to prevent R.F. interference to the logic and video generating circuits of the unit. This ter-

minal is well bypassed and is designed in a metal enclosure to minimize any interference prob-

lem.

New Federal Communications Commission (Part 15) regulations require that the following cau-

tion notice be published:

Warning: This equipment generates, uses and can radiate radio frequency energy and if not

installed and used in accordance with the instructions manual, may cause interference to radio

communications. As temporarily permitted by regulation, it has not been tested for compliance

with the limits for Class A computing devices pursuant to Subpart J of Part 15 of the FCC rules

which are designed to provide reasonable protection against such interference. Operation of

this equipment in a residential area is li ely to cause interference in which case the user at his

own expense will be required to ta e whatever measures may required to correct the interfer-

ence.
