cmOS Engineering


The cmOS Engineering LCP1 is an NMRA/LCC/OpenLCB compliant node implementing a CAN segment 32 Producer/Consumer layout interface. Additionally, a further 20 producers/consumers are included in the form of logic elements.

Interface Elements: Are divided into 2 groups (Port A) and (Port B) of 8 elements. Each element can be individually configured as an input or output, active high or active low, given a meaningful name, and activation/deactivation event IDs assigned. Additionally, two ports of 8 elements each are provided which provide additional layout interface capability. These two ports interface directly with cmOS Engineering Layout Interface Cards (LIC) details of these are available here.

Logic Elements: Each logic element can be configured as a Timer (0.5,1,2,4, or 8 seconds), or logic function (and/or/xor/nand/nor)
