the connection terminals. (To disconnect the cable, press the button while pulling it out.) Use the hooks to secure
the cable.
R To connect wires, press the wire release button with a pointed object such as a screwdriver while inserting the

R Refer to 4.5.2 Wire type and maximum wire length (Page 31) for information on the type and length of wires that
can be used.
4.5.4 Distribution box switch settings
The distribution box has 3 types of switches that determine how it operates.
DIP switches
DIP switches determine the distribution box number (1–7) of each distribution box in the branch.
Terminate switch
Set this switch to the "on" position for the last distribution box in a branch. Set this switch to the "off" position for all
other distribution boxes in the branch.
Repeat switch
Determines whether the distribution box is used in distribution mode or repeater mode.
In distribution mode, distribution boxes are connected in serial (up to 7 per branch) and up to 20 main monitors can
be connected to each distribution box. In repeater mode, distribution boxes are connected in serial (up to 7 per branch),
with one distribution box in a branch can be used only to forward signals from one distribution box to another. This is
useful when you need to extend the maximum distance between 2 distribution boxes. No main monitors can be
connected to a distribution box that is used in repeater mode.
Note:
R In order to help prevent operating problems or other issues from occurring, recheck the switch settings after
completing the wiring.
R If problems occur after installation, refer to 7.1 Basic troubleshooting (Page 62) or the following website.
