Fig 5.5 

(4)  Secure the communication line with the wire clamp on the electric box. 
(5)  In order to ensure the reliability of communication between IDU and ODU and the 

communication among each IDU, add a matched resistance (supplied in a package 
before ex-factory) on the wiring board of the last indoor unit in a series connection. 
The matched resistance should be connected in parallel between terminal screw D1 
and D2, as shown in Fig 5.5.
