K4LCN16 (51403519-160) LCN Processor Board

The K4LCN16 (51403519-160) is the latest version of the LCN processor board, featuring the Motorola 68040 processor and 16 MW of non-expandable memory. Like its predecessor, the K2LCN, this board includes an integrated LCN interface. The K4LCN board consolidates two previously separate components: the Kernel (processor) and LCNI functions.

Memory and Usage

All K4LCN boards sold by Honeywell come with 16 MW of non-expandable memory. However, many LCN node applications do not require the full memory capacity. For instance:

• The NIM (Network Interface Module) uses no more than 4 MW.
• The Universal Station requires no more than 8 MW.

Digital Clock Synchronization

The K4LCN processor series can generate and receive digital clock synchronization data frames, transmitted at the LCN standard rate of 5 MHz.

Processor Compatibility

To support R500 software, the minimum memory capacity required for the node processor is 3 MW. A K4LCN (68040) processor is highly recommended if your UCN is heavily loaded or if it includes a High-Performance Process Manager device.

The K4LCN-16 processor board is now in its third generation. The first- and second-generation K4 boards had replaceable memory, allowing upgrades to higher memory capacities.
