Friday 8th May – tested the MiniTracker II [https://www.avidid.com/products/minitracker-i but with an RS232 cable] device with the NMR colony and received adequate readings from nearly all critters that passed through the tube.

The device does need resetting periodically – testing the timeout on this there appears to be no logical pattern, so as it is a low overhead I’ll send a character to each reader every 30 secs, and test this.
How to test?

  • Establish the mean average frequency between readings
  • Look for a number of segments of time when no data is coming from the device, that is above this average frequency.

Last week a total of six trackers were ordered and paid for. There is a possibility that we need an extra one if we want to establish time spent within the tubes and within each housing element.
