(0x0127)
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 Beijer Elec-
tronics Nautic Monitors use also the upper four bits, that indicate a group of moni-
tors in a network (max. 14 groups). The monitor grouping is activated, if the
software configured monitor address is used (i.e. the DIL/DIP switch settings are ig-
nored). This function returns the configured group that the monitor belongs to.
Supported since Firmware Version
MT230 Nautic Monitor: 1.2-C118
