17600 – System Data
System data consists of 6 bytes. The first byte has the current alarm contact settings. Each
bit corresponds to a contact. Bit 0 (lsb) is the bit for the Power Supply alarm, and bit 3 is
the bit for the 'any' alarm. The next byte is for the installed card inventory. A '0' bit means
the card is installed and a '1' bit means the card is removed. The other bytes are for
internal use.
17601:17603 – Card Data
Each I/O card in the router has an associated TCP port. Card 1 uses port 17601, card 2 uses
17602, and so on. The data is formatted as follows:

◦
