Addressing for dimming and commands

4.1

NET ID and Unit numbers (ID)

NCOM uses auto addressing (NET-ID =logic address), which ensures that you always have access to the entire network. Even
though there are duplicate unit numbers in use. The first unit (monitor or NControl*) in the chain is assigned logic address 1 and
acts as master for the chain.
It is also possible, without additional settings, to add peripheral equipment such as Ncontrol and VariCap. A user who does not
use the advanced functions such as control with the PLC will not notice a NET-ID. The NET-ID is also used to exchange dimmer
data in a fast way, so that you have a nice smooth dimming function, regardless of the number of sources.

A unit number can be set by the user in the NCOM app. All commands sent by an external controller (PLC. PC etc) will be
distributed in the daisy chain by the master. A reply will always be given by the master, NET-ID1

*) NControl is a 4.3” touch screen device to control dimming and functions of the monitors in the chain.
