3. IDU and ODU communication
A
HyperLink communication (with independent power supply)
Single unit: HyperLink communication is a new type of IDU and ODU communication technology. When the IDUs
are provided with independent power supplies, use 2×1.5mm
are located at terminal block "CN10" of the main control board. There is no distinction between negative
and positive electrodes. For details, see the following figure:
[ Caution ]
Do not connect the HyperLink communication line to the PQ or D1D2 communication line.
System: The HyperLink communication line with an independent power supply between IDU and ODU can reach a
length of up to 600 meters, supporting any topology connection. The following figure shows a serial
connection:
