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.
Bit 0: Input 1 change: 0 =
Did not trigger message, 1 =
Triggered message.
Bit 1: Input 1 state: 0 =
Closed, 1 = Open
Bit 2: Input 2 change: 0 =
Did not trigger message, 1 =
Triggered message
Bit 3: Input 2 state: 0 =
Closed, 1 = Open
7
Standard Message
Sub-Type
4
Bits (7:4) Standard message
sub-type code. Value is 0 in
the location message.
