ACKUP

software and the charts will be re-installed from the setup DVD and the charts CD/DVDs. The
user data will be restored from external storages backup. See the Backup section for details.
W NMEA
IRING AND
The most of installation issues and faults stem from one of two causes:
The connecting cables are not wired correct, or are picking up interference, resulting in a
•
non-working or unreliable installation.
Instruments have not been set up to ensure that the correct data gets from one point in
•
the system to the other.
Clearly getting the cable connection right is the first step in troubleshooting.
C
ONNECTION TESTS
When one or more input and/or output devices are connected to the computer, the
connections must be tested to ensure that all is working correctly. The ECDIS900 provides a
useful tool to help perform this test.
Hyperterminal is an application built into Windows XP and Windows 7 that allows testing of
connections to the input devices. If input devices are connected correct, Hyperterminal
displays recognizable characters. Incorrect connected input devices either show no
information, or garbled characters.
NOTE The Sensor Monitor application must be closed before using Hyperterminal
