User manual FURUNO FI-302 OPERATORS MANUAL

[. . . ] The Nexus Network is capable of carrying data 10 times faster than NMEA 0183. The connection system, with a single 5 mm (1/5") cable and 4-pole jack plugs with cable protectors, makes the installation easy. The connections at the Server are colour coded and marked with a number for easy reference. The instruments large display gives you very good viewing possibilities from any angle, even in bright sunlight. [. . . ] At first power on after installation, you will be asked to press SET (PrESkey). This will give the instrument a logical ID number on the Nexus Network. To initialise the instrument, press SET on all installed digital instruments, one at the time. Note: Always wait for the text "Init OK" to be displayed, before you press SET on the next instrument!The Server automatically gives the first unit ID number 16, then 17 and so on. The order in which you press SET is the same order as the instruments will be given a logical ID number on the Nexus Network. The example shows that the instrument version number is 2. 0 and the given logical ID number is 16. On the lower line, the bus master version number (4. 8) and ID (0) is displayed. 4. 2 Re-initialising the instrument If two instruments by mistake have the same ID number, this can cause disturbance and block the information on the data bus. To re-initialise the instrument, press CLEAR during the power up sequence when version and ID numbers are displayed. The display self test is then re-started on all instruments and you will be asked to press KEY on each instrument as explained above. Note!If you do not succeed to re-initialise, we suggest you disconnect all but one instrument with the same ID number, then repeat the above procedure. 15 5 Operation 5. 1 About this manual · · · In this manual each time a push-button is refereed to, the push-button name will appear in bold and CAPITAL letters example PAGE.
