Locator1 – character that represents where a sensor packet entered the
repeater network. (" ", "a"-"z" and "A"-"Z"). Normally set to NULL(0)
for Wifi sensors.
Locator2 - character that represents where a sensor packet entered the
repeater network. (" ", "a"-"z" and "A"-"Z"). Will be identical to
Locator1. Normally set to NULL(0) for Wifi sensors.
Sensor Pkt – (29 bytes) sensor packet. (includes the CR terminator) Set to
all 0’s (NULL) if no sensor packet is received in 30 seconds. See the
document "Point Six Wireless Transmitter Packet-Data Specification"
for more information about specific sensors.
Org – originator type that generated the packet. 0 – Wifi Sensor; 1 – Link
Manager; 2 – Ethernet Point Repeater; 3 - Application
Transmissions
+
– (3 bytes) number of transmissions since last reset. 0 for
UDP PassThru packet.
Max Transmissions
+
– (3 bytes) maximum number of transmissions for the
power source (0 to 16777216 where 0 is unlimited) 0 for UDP
PassThru packet.
Period
+
– (2 bytes) transmit period in seconds. 0 for UDP PassThru packet.
Reserved – (3 bytes) set all bytes to 0.
+
Most significant byte is first.
Estimated Battery Life Percentage = 100 – Transmissions/ Max Transmissions *100
Estimated Battery Expiration = ( Max Transmissions – Transmissions)* Period
Note: UDP Sensor Packets that include only Data1 are 63 bytes. UDP Sensor
Packets that include Data1 and Data2 are 75 bytes. Older sensors contained Data1
but not Data2. Newer sensors include Data1 and Data2.
