6.1.12 Errors
This option is primarily used to interrogate the HS 2000 network
and is designed for use by service technicians to ascertain levels
of interference that may be present, for example, interference may
be induced by an SSB transmitter or radar. The display shows the
number of messages that have not been transmitted correctly in
the first instance; between 10 and 20 errors per minute is quite
normal. A higher number of errors can indicate that the network
terminators are incorrectly fitted.
6.1.13 Remote
This option allows the user to invoke internal RAM, PROM and
basic network checks for any remote processor node connected to
the network, and display the appropriate error messages on the
FFD. Node numbers are allocated when the system is first
switched ON or following a system reset. In a system comprising a
main processor and performance unit alone, the node 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 10 seconds, it can be assumed that
the node under test is not part of the system. The REMOTE tests
for the currently selected node can be exited by holding Enter
down and pressing the On/Off Illumination Key.
6.2 DEPTH SOUNDER
Fault finding on the Depth Sounder is often difficult since depth
sounder performance is dependent on many factors, including:
transducer type and installation, boat speed, electrical noise, sea
state, sea bed conditions, air and plankton in the water.
Indications of problems with the Depth Sounder normally manifest
themselves in one of three ways:
The display shows:

The display locks down showing depths in the range 0 to 1.5m or
display shows random deep depths.
