Event Log Summary

Event Date Event Type Comments
2/23/2018 7:18:04 AM General I reset the time on the reader. High noise on the antenna is making it difficult to read the virtual tag. So, tag file uploads have been intermittent .
9/22/2016 11:54:11 AM General I updated the IS1001 firmware to version 1.6.1
