I came close to thinking I had a major problem with my trackers a few minutes ago. The management console tells me what is happening by VehicleID. I had two units returning data, one with 83 and the other being 88. These units should return data in order, and I was quickly looking at the data and saw that the time went backwards. [Expletive Deleted]. When I then looked more closely I found that it was two vehicles reporting, and one was slightly behind the other one.

And one of my clients rang with an issue – He commented that he could get a serial cable working only when it was plugged into the serial port and the USB port through a serial converter… But unplug from the serial port and the data input into the USB port would die. Really strange. I think that there might be a cable problem there – maybe the ground wire has come off. That MIGHT explain some of the issues. Without going into the clients office it is hard to see what is going on.
