Note
1. Two poles of SW2, SW3, SW4 and SW5 should be set to the ON position to terminate
two terminating resistors on a line. (default ON)
2. Terminating resistors and selectable switches are introduced only on PCB issue 3 or
later, but not on PCB issue 1 and 2. So if you use BRIB issue 1 and 2, the external
terminating resistors are required. For the external termination, you can get the
terminating unit locally or use GDK-162/100 TERM, which is the terminating unit with 4
P-to-P connections provided by LGE.
