Wilotechn New thinking User Manual for dual incubatino kiwi Diagnostic Transmitters V2 0 GSK 1 0 Background A Diagnostic transmitter for dual incubating kiwi has been developed specifically for the GSK species The Diagnostic transmitter developed for GSK has been designed to assist in any possible future development work for an Egg Timer transmitter for GSK and to assist current management in the mean time The transmitters have 16 outputs but do not report headline behaviour and consequently have only two background pulse rates 40ppm for all states other than mortality and 80ppm for mortality They output cumulative activity in 24 hour periods for the previous 14 days a twitch counter value and finally the number of weeks remaining before the battery is expected to go flat A description of these outputs is provided below 2 0 Turning a transmitter on or off Over view The radio output of a transmitter can be turned on and off using a magnet At the time of turn on the user may set the time of day in hours after midnight Whilst this is advised it is not compulsory If the time of day is set correctly then the transmitter will automatically adjust itself so that it rolls over each 24 hour period at 0800 in the morning If the time is not set at turn on then the transmitter will roll over the 24 hour periods in synch with the time that the transmitter was turned on Setting the time at turn on means that transm

8. ly move the magnet away briefly and return it to the transmitter The transmitter will start to output pulses at a rate of one every 1 5 seconds Each pulse represents one hour after midnight Count the pulses as heard and remove the magnet when the count gets to that desired Ie if time of turn on was 3pm the time would be set as 15 hours after midnight therefore requiring the magnet to be held in place until 15 pulses had been counted Once the required number of pulses has been heard the magnet can be removed and the turn on sequence is complete If the time set function is used a partial non 24 hour first day will be created any activity that occurs during this partial day is ignored Ie if a transmitter is turned on at 3pm the first partial day will be 17 hours long and the first full day will be from 0800 the next morning If a transmitter is turned on at midnight then the time should be set as 24 hours after midnight since it is not possible to set zero hours after midnight After turn on the first output number will be hijacked and report the version number of software in the transmitter and the same will be true of the second output number which reports the number of hours after midnight that was set Checking the time set after turn on To check the time that has been set the user may listen to the outputs Immediately after turn on the transmitter will output 10 pulses at a rate of 40 pulses per minute one pulse every 1 5 second
9. s the output sequence will then start and be transmitted to the user in the format described later The first number set is for activity yesterday and the second for activity two days ago After turn on these two output slots are hijacked and are used to transmit the software version number and the time of turn on that has been set The version number is inserted in the activity yesterday slot and the time of turn on is inserted in to the activity two days ago slot If the time is not set at turn on then a pre initialised value for activity will be output in the activity two days ago slot The software version number and time of turn on are cleared at the end of the first partial day If a mistake is made setting the time turn the transmitter off and try again it s fun you ll enjoy it 2009 06 12 Diagnostic TX User Manual GSK V2 0 doc Page 2 of 6 3 0 Pulse rates Diagnostic transmitters output 2 different pulse rates 40ppm incubating and not incubating ie Alive 80ppm mortality 4 0 Outputs 4 1 Over view and explanations The alive and mortality pulse rates are broken every 10 minutes by a series of 16 outputs as described in the following list 1 Activity Yesterday 2 Activity 2 days ago 3 Activity 3 days ago 4 Activity 4 days ago 5 Activity 5 days ago 6 Activity 6 days ago 7 Activity 7 days ago 8 Activity 8 days ago 9 Activity 9 days ago 10 Activity 10 days ago 11 Activity 11 days ago 12 Activity 12
