When issued alone without the [mask] option, the ERRS command returns the current error status of the transmitter. Possible errors, their codes, and the corresponding hexadecimal values are described in Error messages.
You can use the [mask] option to define the possible set of errors that causes NMEA messages to be marked as invalid. The error mask is a hexadecimal number formed by combining the hexadecimal values of the desired errors. By default, the mask is 1010, which means that the NMEA data is invalid only if both wind sensors are missing or broken or stuck (presuming the corresponding alarms are activated).
For example, if you want the mask to include errors number 10 and 11 (0400 and 0800 in hex), the desired mask value is 0C00:
0400 + 0800 = 0C00
