RTC ERROR Input RTC

When communication between CPU and RTC stops, it is outputted by pop-up window.

In case this pop-up window is shown, failure of the RTC board can be considered.

8.1 Self-test and Error Message

Note:

Continuous alarm sounds

When DSP detects CPU malfunction, alarm will go off. U20: DSP and U30: CPU are in constant contact. If CPU does not respond to a command from DSP, DSP will recognize this as an error and alarm of 2200 Hz will continuously go off. Then, key input and LCD indication will freeze up. Since there is no display function in DSP, alarm will go off instead of showing a pop-up window an as error.

When detecting abnormally functioning antenna

During a continued transmission R-VSWR voltage and F-VSWR voltage are checked three times after 5, 6 and 7 has passed from the start of the transmission. If RVSW voltage is over its designated voltage, APC functions to reduce PA output.

8.2 DSC Communication Test

8.2 DSC Communication Test

This is a communication test between FM-8800S/Ds. Conditions under which this can be done with the same MMSI are below only:

- CALL TYPE: Individual (SHIP CALL) - CATEGORY: Routine

In this case, TX output of CH70 will automatically be reduced to Low Power.

NOTE:

FM-8500, etc can receive signals with the same MMSI. For example, No.2 VHF DSC can receive a DISTRESS CALL or ALL SHIP CALL from No.1 VHF. This tends to confuse a user. Therefore, when receiving the same registered MMSI, it will not carry out RX processing of messages other than messages set up by above-mentioned setup.

Fig. 8.2.1 DSC Communication Test

Procedure

1. Carry out a DSC test from No.1 VHF to No2. VHF.

Press CALL key on No.1 VHF to create DSC message.

- CALL TYPE: SHIP CALL

- SHIP ID: No.2 VHF MMSI (Input Own ship) - CATEGORY: ROUTINE

- TCmd 1: SIMPLEX TP

- TCmd 2: NO INFO

- CH: CH6

2. As for a setup procedure for No.2 VHF, Select [MENU] -> AUTO ACK -> and set COMPLY STATUS setup to “ABLE”. In addition, set Handset/Remote Handsets to

“ON HOOK”, and to any channel.

3. Press CALL key on No.1 VHF for longer than three seconds. Then, “CALL IN PROGRESS ON CH70” will appear and after transmitting from CH70 “WAITING FOR ACKNOWLEDGEMENT” will appear. Then, wait for the ACK BQ from No.2 VHF.

4. When receiving ACK BQ from No.2 VHF “ABLE ACKNOWLEDGE CALL RECEIVED” will appear and alarm will go off. If you press [CANCEL] key, a display will switch to VHF display and CH6 will be automatically set up.

5. With No.2 VHF, when receiving a call-up from No.1 VHF, ACK BQ will immediately transmitted and alarm LED will blink and alarm will go off for 5 seconds. “ABLE ACKNOWLEDGE CALL IN PROGRESS” will appear on the display.

6. Press [CANCEL] key, alarm will stop and transmitted message will appear.

7. Press [CANCEL] key a display will switch to VHF display and CH6 will automatically be set up.

8. You carry out voice communication by CH6 between No.1 VHF and No.2 VHF.

9. The same procedure is taken to carry out a DSC test from No.2 VHF to No.1 VHF.

Call up the option menu with reference to page 4-1. Select [MENU] -> SYSTEM ->

[ENT] -> and input the password. This section explains what T/A, TEST, and REST DSP are.

8.3.1 T/A

You can carry out DSC RX TEST by selecting this item and pressing [ENT] key. This checks the reception sensitivity on CH70 RX board and monitors DSC signals from other ships.

DSC RX TEST OUTPUT RX DSC DATA

TO NMEA PORT EXT : ENT

IF signal: 37.5 kHz from CH70 RX board is inputted into U17: CODEC and is converted into audio frequency of 1700 Hz±400 Hz. Then, it is outputted into the Handset ear-speaker and SP of the Transceiver unit. A converted frequency just mentioned is digitized and is outputted into TXD LINE (#1-#2) on IEC61162/REMOTE port on RS-422 level. This signal is not converted into DSC characters but is used as a DSC RX raw data for type approval.

1.2 MEMORY TEST

There is no need to select RAM, ROM and EEPROM separately to carry out a memory test. Just open a window shown on the right and the test results show in it.

- RAM : is a test for U31 on CPU board and checks Read/Write. RAM is used for CPU working

area.

- ROM : is a test for ROM for built-in U30 on CPU board and checks the checksum. Main program is stored in ROM.

- EEPROM : is a test for U29 on CPU board that checks the checksum.

System setup value and communication log are stored in EEPROM.

1.3 PRINTER

Enter this menu and connect a printer. If you press ENT key, “FM-8800 PRINTER TEST” will be printed out.

NOTE:

Printer: individual test for PP-510

- Turn on the power whiling pressing LF key:

Printer's self-test will print out all of characters until you turn the power off.

!”#$%&’()*+,-./0123456789:;<=>?@ABCDEFGHIJKL --- Turn on the power while pressing NLQ:

DIP SWITCH SETTINGS PRINT OUT will be carried out

Printer: individual test for μTP-80F For test printing:

1. Turn on the printer while pressing and holding down FEED switch.

2. All characters are printed out and then five line pattern is printed.

The printer is on-line after test printing.

- In case of PE during the test printing, returns to the state of PE after printing a line.

- To cancel the test printing, press SEL switch. It stops printing and changes to ON LINE in a few moments.
