Chapter 1 General FAX-30 is a weather facsimile receiver. The received facsimile image is displayed on the NavNet display unit and a PC. 1) NAVTEX function is not compliance with IMO standard. (For Non-SOLAS ship) 2) When FAX image is being received, NAVTEX message cannot be received. 3) The PC is required to run a web browser such as NETSCAPE or INTERNET EXPLORER. 4) Automatic station selection mode for NAVTEX reception requires position data from the GPS. 5) When both the PC and NavNet are connected, FAX-30 is operated from the PC. 6) Receiving priority (1) In FAX&NAVTEX mode, NAVTEX message is received except for the time set by the timer. (2) In FAX&NAVTEX mode, the priority is as follows. FAX manual reception > FAX timer reception > NAVTEX reception (3) The auto reception by receiving FAX start signal is valid only in FAX ONLY mode.

MAIN board

Chapter 2 Circuit Description

MAIN board (08P3218) MAIN board consists of CPU, NET and PWR circuits. CPU circuit CPU consists of 32-bit CPU&DSP with a built-in Ethernet controller, 24-bit CODEC (AD converter), Flash ROM and SDRAM. The main function of CPU&DSP (U18) is as follows. 1) 2) 3) 4) 5) 6)

Filtering of received signal (DSP) Demodulation of FAX data (DSP) Demodulation of NAVTEX data (DSP) Communication with NAVNET or PC (CPU) Processing position data for auto NAVTEX reception (CPU) Setting the receiving frequency for RCV circuit (CPU)

FAX signal (16.29 kHz) and NAVTEX signal are AD-converted by the CODEC and sent to CPU&DSP. Flash ROM memorizes the system program and the image for backup. SDRAM memorizes FAX image.

Chapter 2 Circuit Description

RCV board (08P3219) Three bandpass filters, FL1, FL2 and FL3 locate at the first stage of the receiver. The filter passes the following frequencies. When receiving NAVTEX message, FL3 is used. FL1: 2 MHz to 13.2 MHz FL2: 13.2 MHz to 25 MHz FL3: 80 kHz to 518 kHz The shift register, U10 receives three signals, RCV DATA, RCV CLK and RCV BAND from MAIN board to select the filter. The signal passed through the filter is sent to the first mixer, Q5 and Q6. The first mixer mixes RF signal with the first local oscillator signal, F+53.98371 MHz and outputs the first IF signal, 53.98371 MHz. Further, the signal is mixed with the second local oscillator signal, 54000 kHz at the second mixer, U4. The 16.29 kHz second IF signal is sent to MAIN board.

Chapter 2 Circuit Description

The synthesizer consists of 18 MHz oscillator, Direct Digital Synthesizer (DDS), PLL and VCO. The signals from MAIN board, RCV DATA, RCV CLK, RCV DDS, RCV PLL and RCV BAND, determines the frequency of the local oscillator depending on the selected receiving frequency. When the synthesizer unlocks, RCV UNLOCK signal is generated for the error message. The VCO is adjusted as follows. Setting frequency

Procedure 1. Disconnect the power cable of FAX-30. 2. Connect a PC to “NETWORK (LAN)” connector of FAX-30, using the cross cable 9 pin D-sub 6 pin MJ cable. 3. Change the IP address of PC to “172.31.1.1”. 4. Ensure the subnet mask of PC is “255.255.0.0”. 5. Connect the power cable to FAX-30. (When Windows2000/XP is used.) 6. Run “setup.bat” on PC. 7. Disconnect the power cable from FAX-30 and re-connect it within 1 second. 8. The message, “My IP address 172.31.1.1” appears on MS-DOS window of PC. 9. Connect the power cable to FAX-30. (When Windows95/98 is used.) 10. “loading %” appears. 11. When the upgradation is complete, POWER LED on FAX-30 blinks after about 10 seconds. 12. Disconnect the power cable to turn off the unit. 13. Connect the power cable and confirm that POWER LED on FAX-30 blinks after about 10 seconds.

To check the program number, turn on the unit with DIP switch S1, #2 on MAIN board set to ON.
