Q2: The I-8211W’s GPS/GLONASS led always show “ON” or “OFF” status.

Ans: If the GPS led (green) of I-8211W always show the “ON” or “OFF” status, it means the

I-8211W can’t receive the GPS/GLONASS data.

For some complicated reasons:

(1) The location can’t receive the GPS/GLONASS signal.

(2) No antenna inserted.

(3) Wrong operator parameters.

(4) Hardware data interface (/dev/ttyS*) configured incorrectly.

When this happens:

(1)

Connecting antenna correctly.

(2)

Moving the antenna to the location that can receive the GPS signal.

(3)

Checking the I-8211W device name that you used are correct or reinstall the Linux driver

again (please refer to the “Q1: No I-8211W’s Linux device name?”)

After you have done the above, if the error still exists, try to unplug the power and plug the power
again.
