The K4LCN8 is the 8 megaword version of Honeywell's LCN processor board using the Motorola 68040 processor. Memory on this processor board is expandable. This board, like the K2LCN preceding it, includes the LCN interface on the board.

The K4LCN series of processor card is also capable of generating and receiving digital clock synchronization data frames transmitted at the LCN standard 5 MHz rate.

Processor Compatibility:

The minimum memory capacity for the node processor is three megawords to support R500 software. A K4LCN (68040) node processor is highly recommended if your UCN is currently heavily loaded or if a High Performance Process Manager device is connected to your UCN. The K4LCN4 node processor can be used in any node with one exception. A Universal Station running engineer personality requires a K4LCN8 or K4LCN16 processor to provide the required 8Mw of memory. Honeywell no longer sells the earlier K4LCN4 or K4LCN8 processors, which have been replaced by the non-expandable K4LCN16.
