ALERT 2 station ID is unique Sensor IDs are from 0 to 254 ALERT 2 uses the station ID and sensor ID together to identify a sensor data value Sensor ID ranges 0 to 8 are pre-defined 9 and 10 are defined by Hydro. Lynx transmitters 11 to 99 can be used in your system as needed 100 to 200 used for control 05/06/2014 255 is reserved for time stamp ID 0 1 2 3 4 5 6 7 8 9 10 Sensor Rain gauge Air temperature Relative humidity Barometric pressure Wind speed Wind direction Wind peak Water level Battery Digital status GPS sync state

Common report type supports all sensors, data type, decimal precision Sensor ID range: 0 – 254 Data types: Unsigned integer Signed integer Floating point Decimal precision set by transmitter 05/06/2014

0 5 / 0 6 / 2 0 1 4 The tipping bucket report compresses several rain gauge tip reports into one packet. Sensor ID is usually 0 Timing of rain gauge tips stored to nearest second. Base station software will file each rain gauge tip at the time it occurred. Data receive delays due to TDMA do not effect rainfall data analysis. Hydro. Lynx transmitter report use: General Sensor Report for rain gauge timed reports Tipping Bucket Report for rain gauge tip events

MSR compresses sensor data in an efficient packet An MSR containing 8 sensor readings uses 12 bytes The equivalent GSR for eight sensors uses 36 bytes MSR limitations English units for sensors are pre-defined Wind speed and battery resolution are limited Water level range limit is -327. 67 to +327. 67 feet ID 1 2 3 4 5 6 7 8 Sensor Air temperature Relative humidity Barometric pressure Wind speed Wind direction Wind peak Water level Battery Bytes 2 1 2 1 Format Signed Unsigned Unsigned Signed Unsigned Resolution 0. 1 1 1 1 0. 01 0. 1 Units deg F % mb mph deg mph ft V

Data precision set by decimal digits displayed 0 = integer, >0 = floating point with decimal digits

Set lower and upper limit to prevent negative sensor data

Set rain gage counter mode to Increment Only Supports 3 wire legacy, 3 wire momentary pulse and 2 wire rain gauges One second timer used to filter burst noise and tipping bucket bounce

Transmit all sensor data every hour Sample every 5 minutes and transmit on change Rain gauges transmit TBR data on event (tip)

ALERT 2 Encoder or Repeater connects to COM 2 Transmitter baud rate: 9600

Set ALERT 2 Encoder format for transmit Set ALERT 2 Encoder format for receiver

Air. Link default parameters recommended Change modulation for Maxon SD 125 VE Use inverted modulation

Set FEC to HDR for high data rate Set AGC to 55 milliseconds for HDR Set TDMA Slot Delay to 12 for HDR

Source Address used by base station to identify station data Should match DCU ID Destination address used in two-way control systems only Add path appends repeater ID to packet re-transmitted Do NOT use IND timestamp Let 50388 timestamp data Hop Limit sets number of repeater re-transmit 0 to 6 or unlimited (7)

Hop limit is number of times packet is repeated Hop limit is set at transmitter 0 = No repeat 1 – 6 = Repeat 1 to 6 times 7 = Unlimited repeats When a packet is repeated, the hop limit count is decremented (unless hop limit is 7) When count reaches 0, no more repeats Repeater hop limit Does not affect repeat of packets received Limits repeats of local sensor data Limits repeats of ALERT 1 data concentrator packets
