P/Q communication
Single unit: Use a shielded cable for the P/Q communication and properly ground the shield layer. P and Q ports
are located at terminal block "CN6" of the main control board. There is no distinction between negative
and positive electrodes. Connect the shield layer to the sheet metal of the electric control box, as
shown in the following figure:
System: The HyperLink communication line with a uniform power supply between IDU and ODU can reach a
length of up to 2000 meters, supporting any topology connection. The following figure shows a serial
connection:

For other connection methods (tree topology, star topology, ring topology), please refer to the technical manual or
consult technical personnel.
When HyperLink with a uniform power supply is available, a uniform power supply for IDUs is required. For
details, see "Power Cable Connection".
When HyperLink with a uniform power supply is available, there is no need to connect a repeater to the system.
