16.8.4 ARRANGEMENT OF THE INSTALLATION
OF PCB AND H-LINK TERMINALS
As described in the figure below, 8 PCBs which are built into
HARC-BX E and H-LINK Terminals correspond to the both
sides of the same numbers, 1 to 8 within
respectively.
In order that PCB would be able to communicate with unit it
must be connected to same H-LINK than unit.
