    1.2 RECEIVER CONNECTION The W 4010 demodulator needs audio from the receiver with a level of about 0.1 Vpp, up to a maximum of 5 Vpp. Many receivers have line or tape recorder outputs which have fixed levels, and it is recommended to use these because their outputs are independent from the volume control.

  • Page 3: Printer Parallel Interface

    In case of unreadable video text switch the W 4010 Off, switch On, push [F1] and then [F3]. The pro- grammed values are stored in a non-volatile memory and keep stored even without power. 1.5 PRINTER PARALLEL INTERFACE Before interconnecting the printer with the W 4010, make sure both units are turned off. The 36-pole Cen- tronics printer output jack is located on the decoder's rear panel and is connected via the standardized Cen- tronics cable to the similar jack on the printer.

  • Page 4: Using An External Demodulator

    The parity can be adjusted with help of [F3] to NO, ODD, or EVEN. The programmed values are stored in a non-volatile memory and stay stored even without power. By means of [F1], [F2], and [F3] the operator can easily configure the WAVECOM decoder to communicate with any RS-232C equipment.

    2. The W 4010 bandpass filter has an attenuation of over 27 dB when the input frequency exceeds the fil- ter corner frequencies by more than 200 Hz. This filter response is an optimum compromise between unwanted signal attention and intersymbol distortion caused by filter group delay.

  • Page 6: Level Control

    2.4 LEVEL CONTROL The Model W 4010 has a continuously adjustable squelch circuit which acts upon the signal amplitude: when a signal is below the preset level, it is squelched out completely. Above this level it passes through the squelch with no attenuation.

    2.7 HANDLING OF THE REMOTE CONTROL The new Remote Control of the W 4010 enables the communication between the decoder and a computer (PC/AT) via a serial RS-232- interface. The commands sent by the computer to the decoder will be inter- preted inside the W 4010 and transposed into the equivalent unit settings.
  • Page 8 The operation of the decoder via the keys is also possible during the remote operation. The software regis- trates the manual settings. The changed parameters can be asked via the interface and be evaluated by the But the user can also write his own software or even can steer the W 4010 from the WINDOWS terminal program.

    HINTS The switching to JV-FAX must only happen in DOS. The W 4010 switches the necessary lines for JV-FAX on the demodulator. This switching of the RS-232-steer- ing lines leads to disturbances in WINDOWS. The voltage range of the A/D converter can be adapted to other data between 0 and 5 volts by changing the reference diode.

    DEFINITION FOR SITOR-ARQ ISS Information Sending Station IRS Information Receiving Station The WAVECOM software always decodes the Information Sending Station. The SITOR/AMTOR 7-bit alphabet uses a 3:4 mark to space ratio, however it is not identical to the alphabet No. 3.
  • Page 13 ly one station. This mode consists of a continuous 100 baud data stream with the SITOR alphabet and the shift is standardized at 170 Hz. Each character is sent twice with the second transmission following 35 bits after the first. Only error-free characters reach the output.
  • Page 14 Key [F2] permits choosing one of the four following character sets: ITA-2, Tass-Cyrillic , Third Shift Cyrillic and Third Shift Greek. Third Shift Cyrillic signals are often heard and can be recognized by the continuous switching of the numbers case. The search for the correct character set is made easier because the com- plete screen display is switched instantly.
  • Page 15 With packet radio many stations can be active on the same frequency. Stations are "connected" together and the other channel activity has no influence on stations that are connected together. The WAVECOM decoder offers the advantage that all traffic of a certain station can be monitored without monitoring the rest of the channel activity.
  • Page 16 [PRINT] will have to be pushed (the LED [PRINT] MUST glow). If it is desired to print the next picture, leave the W 4010 in the AUTO MODE, which is the default mode after turn on. A weather picture needs 10 - 40 minutes and when the next picture starts, the LED [TRAFFIC] will glow as the picture is being printed.

    FINE SPEED UP / FINE SPEED DOWN: The FAX picture is only synchronized at the beginning of trans- mission. If there is a small difference in drum speed and the W 4010, the picture will start to drift in one di- rection or the other.

    If the preliminarily entered baudrate has too large a difference with respect to the actual baudrate, the IAS- BAUDRATE measurement can take a very long time. The keys [F2] and [F3] can step the baudrate up or down. The baudrate adjustment via keys [F2] or [F3] is also important for simplex ARQ signals, which often can not be measured.

  • Page 20 The ARQ-M2-242 and ARQ-M4-242 systems correspond to the CCIR recommendation REC. 242. This system combines two or four data channels in a single transmission. It uses a 7-bit code with which transmission er- rors can be recognized. All characters of the ITA-3 alphabet have a 4 to 3 ratio. The Time-Division-Multiplex (TDM) system operates full duplex and the error-correction procedure operates like ARQ-M2, complying with Rec.
  • Page 21 4, 5 or 6 characters. A cycle is twice as long as the block length. If the ISS receives the acknowledgement, then the next block is transmitted with opposite phase. The transmission rate can be chosen from among several Baud rates. The Wavecom software always receives the ISS (Information Send- ing Station).
  • Page 22 The length of the transmitted blocks, the switching of the block lengths, and the data length are detected automatically. The status line show the block lengths as short, middle, or long. The detection of block length switching can be lost in case of heavy interference on the communications channel, in which case the key [F2] should be pushed.

    All microprocessors and various peripherals can generate broad-band radio-frequency interference (RFI), which may be radiated by the interconnecting cables. The WAVECOM equipment is engineered to reduce this RFI to a minimum by utilizing RF chokes on all outputs. A metal case is used to shield the circuitry, and as a further RFI preventing measure, each PCB is individually shielded with copper foil.

    The transportation costs for equipment returned to WAVECOM for repair has to be paid by the customer. If you do not insure the product, you are responsible for any loss or damage in transit. WAVECOM pays for the transportation back to the customer, if the equipment is still in warranty.
