3. SYSTEM CONFIGURATION
(1) ROOT
In the i.LINK system connecting the unit by cables, one device is appointed as the ROOT which plays the role of the system manager.
ROOT is selected every time a new i.LINK system is configured when the unit is connected or disconnected.
ROOT operates as the system manager of the i.LINK system. When appointed as ROOT, the NODE ID which is the contact number in the
current system is set in order from 0 for the other device. The last number (maximum 63) is set as itself.

(2) Cycle signal
With the i.LINK system, periodical (every 8 kHz, 125 µs) sync signals are generated and managed in time division so that the communi-
cation is not interrupted. The cycle signal (8 kHz) ROOT is output every 125 µs. Each device synchronizes with this signal and declares the
start of communication.
start of communication.

As the i.LINK system corresponds to plug-in and plug-out, this sync timing is used to detect the connection and disconnection of new
devices to or from the i.LINK system.
