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.
Byte Number Variable Bits Description
0
Type field 2
Bit (1:0) = 0 = Standard
message type:
0
Battery state 1
Bit (2) 0 = Good battery. 1 =
replace battery.
0
GPS Data Valid 1
Bit (3) 0 = GPS Data valid in
this message. 1 = GPS failed
in this message cycle, ignore
Latitude and Longitude fields.
0
Missed Input State
Change
2
Bit (4) Missed Input 1. A
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.
Bit (5) = Missed Input 2. A
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.
0
GPS fail counter 2
Bit (7:6) = GPS fail counter.
Counts up to a maximum value of
3 upon GPS failure.
1,2,3,4,5,6
Latitude/Longitude 48
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
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
7
Input Status 4
These bits reflect the state of
the inputs and indicate which
one, if any, triggered an Input
Status Changed message.
