KAD/ENC/111

The KAD/ENC/111 is a CCSDS encoder with an Ethernet interface and a 64 MB internal memory buffer. It is used to wrap UDP packets received over Ethernet into CCSDS frames of fixed length of 1,279 bytes. The KAD/ENC/111 has two modes of operation, which can be controlled from the KAM-500 backplane. In the first mode, the module interleaves real-time data received over Ethernet with idle data generated by the module.

In the second mode, the module interleaves real-time data received over Ethernet with data read from the internal memory buffer. There are two ways to switch the KAD/ENC/111 between modes, either by the internal timer (default) or by command from another KAM-500 module through the backplane. The module has four RS-422/485 outputs which are buffered copies of the single CCSDS channel.
