Help! My WISP, Reader, etc. doesn't work!

My WISP won't program
The latest programming adapters have an LED which should be ON if everything is connected properly.
To troubleshoot the old adapters:
a. You may have the JTAG cable backwards on the programming board. On the
note the white dot to the right of the JTAG 2x7 header - this should align with the red stripe on the cable.
b. You may have the wisp connected backwards. Try it the other way.
If you are hardware savvy, measure the voltage between vdd and ground on the programming adapter. It should be the same as the selected voltage in iar project options. If the It flashes between 0 and roughly 1V (it probes and sees a short if its backwards). The debugger may not output voltage until after the first attempt at programming. Try programming and test the voltage after the error occurs.
I can't connect to the reader via the web app
Make sure you have power and ethernet connected.
Your network may not support the
addressing. Try getting the ip address through the serial port. See

Can you read a commercial tag?
Is the WISP oriented towards the reader?
I can't get the C# app to connect to the reader
Make sure you can connect via the web app
