Input Status Changed Message
This is the message that will be transmitted upon the change of state of
the inputs if enabled and as selected by the user Input 1 open, input 1
closed, input 1 both, input 2 open, input 2 closed, input 2 both. The
Message Sub Type is 3. The Input status value of byte 7 in the message
indicates which input changed state to trigger the message and also
reports the states of both inputs. The message format is shown in table 5.

Description
Bit (1:0) = 0 = Standard
2
message type:
Bit (2) 0 = Good battery.
1
replace battery.
Bit (3) 0 = GPS Data valid in
this message.
1
in this message cycle, ignore
Latitude and Longitude fields.
Bit (4) Missed Input 1.
value of 1 in this bit means
that an input state change of
Input 1 was missed due to the
transmission of a higher
priority message.
2
Bit (5) = Missed Input 2.
value of 1 in this bit means
that an input state change of
Input 2 was missed due to the
transmission of a higher
priority message.
Bit (7:6) = GPS fail counter.
2
Counts up to a maximum value of
3 upon GPS failure.
Byte 1 = Latitude MSByte
Byte 2 = Latitude
Byte 3 = Latitude LSByte
Byte 4 = Longitude MSByte
Byte 5 = Longitude
Byte 6 = Longitude LSByte
360 degrees of Longitude coded
48
in signed binary with 3 bytes
and 180 degrees of Latitude
coded in signed binary with 3
bytes.
Positive Longitudes correspond
to East Longitudes
Positive Latitudes correspond
to North Latitudes
These bits reflect the state of
the inputs and indicate which
4
one, if any, triggered an Input
Status Changed message.
