6-5
6.1.6 PROM
This tests the correct operation of the FFD's program memory and
calculates its checksum by adding all the individual bytes of memory
together. The total is displayed in hexadecimal in the bottom half of the
display and the last two digits are the software version number. If this test
fails then if possible, FATAL ER 02 is displayed, and further operation of the
FFD cannot be accurately defined. The upper half of the display shows the
FFD's network node number.
6.1.7
EEPROM
This tests the correct operation of the FFD’s non-volatile memory where the
display's settings are stored when power is switched OFF. If this fails
FATAL ER 03 or FATAL ER 04 will be displayed. The display's page
configuration and possibly the text for some functions will be lost.
6.1.8
Lighting
This test checks the correct operation of the display lighting control cycles
through the red and green lighting at the three illumination levels.
6.1.9
Debug
CAUTION: This test is not for normal use, since it may seriously
affect the operation of the Hydra 2000 System.
6.1.10 RES-SYS
CAUTION: Do not use this option during normal operation as all
calibration values will be lost.
This allows individual units or the entire system to be reset. The network
node address of the unit to be reset is selected using the Scroll Up and
Scroll Down Keys and then Enter pressed. The node allocations are as
follows:
01 - Depth Board 05 - Wind Board
0D - Expansion Board FF - Entire System
