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

Input Status
4
These bits reflect the state of 
the inputs and indicate which 
one, if any, triggered an 
Undesired Input State message. 
Bit 0: Input 1: 0 = Desired, 
1 =Undesired. 
Bit 1: Input 1 state: 0 = 
Closed, 1 = Open 
Bit 2: Input 2: 0 = Desired, 
1 = Undesired 
Bit 3: Input 2 state: 0 = 
Closed, 1 = Open
