Monitor Group
Besides the standard addressing scheme, where the lowest four address bits in field
ADR are used to address a total count of 16 monitors in a network, the Lauer Navi-

network (max. 14 groups). The monitor grouping is activated, if the software config-

function returns the configured group that the monitor belongs to.
