Console ANI Programming
234 025-9533Y
The format of the data is shown in Figure 45 .
Figure 45: GE-STAR Data Format
Typically, the GE-STAR information is transmitted in a short burst of three repeated
messages of the above format, proceeded by a 16-bit preamble of alternating 1’s and 0’s.
The repetitions and error detection on each message provide immunity to falsing and high
decoding reliability.
Output Format
The GE-STAR ANI output will display on a console as a sequence of characters and
numbers that represent the decoded GE-STAR ID. For non-emergency ANI numbers, the
display shows the four-digit ID number (0000-9999), followed by a status or message
character if present in the transmission. For emergency ANI numbers, the console sounds
an alarm and displays the four digit number (0000-9999), followed by a status or message
character if present in the transmission. The possible outputs are shown in the following
tables:
