PIL and WMO Product Details

The NWWS 2000 will support both CRLF and CRCRLF as end-of-line indicator. However, when NWWS 2000 converts the PIL or the Transition WMO message to the NWWS WMO Message Format, the CRCRLF sequence will be used as the end-of-line indicator instead of CRLF.

See samples of the product.
