TReX User Manual v2.14 Firmware
LINK FAIL TIME
This is the number of seconds (up to 240) that is allowed to pass in-between received messages
without setting the LINK FAIL output (if LINK FAIL output is configured).
ALERT
Visual notification and repeating beep (at a configurable interval) when a message is received
that meets the conditions for raising an alert. See
ALERT FILTER
.
If the ALERT output is enabled the configured output will also operate.
Can be configured from 0-250 seconds. When set to 0 the alert is disabled.
DEMOD
Access to the raw signal demodulation screen allowing raw data and recovered clock signals to
be viewed in real time.
FILTERS
The TReX supports the use of message filters. These filters inspect the content of incoming
messages and then make decisions on whether to ignore or pay attention to these messages
based on filter setting.
There are 3 types of supported filters:
•
Include filters (messages must include one or more of the matching entries).
•
Exclude filters (messages must NOT include any of the matching entries).
•
Alerts filters (Alerts are raised for message with any of the matching entries).
Alert filters take priority over Exclude filters. This means that if “PUKEKO” has been
specified in ALERT.TXT and “FIRE” is specified in EXCL.TXT then a message with “FIRE
AT PUKEKO PLACE”, although it would normally be excluded, would still raise an alert and
display the message.
Each of the filter matching entries are NOT case sensitive and can be part of a longer word or
phrase.
Entries are allowed to be more than one word e.g.
THIS IS A TEST
This will match on “ThiS is a TEST” but not the single words in the entry, unless they have
been added as separate match entries.
Up to 15 key words can be stored, each up to 20 characters in length. There must be no ASCII
