Note
When the system is reset all calibration, damping and alarm values will be
set back to default settings, all log values and trip functions will be reset to
zero. All display units will reset to their default page settings. After a delay of
about 20 seconds the system should be switched OFF and then back ON
twice to complete the reset procedure.
6.1.11 Versions
This option allows the user to obtain the software version numbers for the
FFD (DISPLAY), Depth board (DEPTH), Wind board (WIND), Expansion
Unit (EXP UNIT) and Pilot, if fitted. With 'VERSIONS' flashing on the display,
press Enter. Then use the Scroll Up Key to select the option whose version
number is required and press Enter to display the software checksum of the
appropriate unit, in the bottom display. The last two digits of the checksum
are the software version number.

that have not been transmitted correctly first time. Between 10 and 20 errors
per minute is quite normal. A higher number of errors can also be an
indication that the network terminators are not correctly fitted.
6.1.13 Remote
This facility allows the user to invoke internal RAM, PROM and basic network
checks on any remote processor node on the network, and display the
appropriate error messages on the FFD. Node numbers are allocated when
the system is switched ON for the first time or after a system reset.
In the Hydra 2000 System the numbers will be:
Depth board 1
Wind board 5
In a system with additional processor nodes it may be necessary to
determine the individual node numbers by disconnecting nodes in turn and
running the remote PROM test. If no pass or fail message is displayed within
