Panasonic WJ-ND300A Installation Manual page 17

When connecting two extension units or more, connect them as follows. Up to 6 extension units can be connected to a single
unit. When connecting the units newly, observe the following important notice. Refer also to the operating instructions of the
extension unit.
Important:
• When connecting extension units, connect them as shown in the illustration below. When connected in a different way, the
unit numbers may not be distributed correctly. In this case, the units may not be recognized correctly.
Example: When installing 5 extension units, connect the unit of unit number 1 first, and then connect the other unit in the
order of the unit number. When adding an extension unit, connect the unit of unit number 6 as described in the illustra-
tion.
• After running the system with the extension units, do not change the connection such as exchanging the unit numbers
between the units. Otherwise, the unit numbers may not be distributed correctly and the units may not be recognized cor-
rectly.
• Refer to page 35 for how to check the unit number of the connected extension unit.
