7.1.2 Large Synchronized Network
When building a large local Lonworks network (more than 10 scanners), an SC6000
Controller must be used together with a PWO power supply/junction box unit. In this case the
SC6000 unit acts as the system master and is connected to the host through one of its
interfaces.
All scanners act as slaves and are connected to the SC6000 through the PWO power
supply/junction box. For DS8100A scanners, 4 branch connectors provide Lonworks
communications between the scanners and the SC6000 unit. The last scanner on the line
requires a Termination connector as well as any unused branches in the PWO unit.
The allowed maximum bus length is 65 m.
External devices such as a presence sensor and an encoder are all connected to the PWO.
