1. GENERAL DESCRIPTION
The N-8640SB is an IP door station assembly kit consisting
of Main and Sub PC boards, cables, and mounting hardware
(excluding the operation panel) of the N-8640DS IP door station.
You can make the IP door station suitable for applications using
this kit in combination with the operation panel section to be
prepared separately.
Use the N-8000 Setting Software* to perform settings. Set up the
same items as those for the N-8640DS since the N-8640SB is
handled as the N-8640DS on the software.
Settings and operations are the same as those of the N-8640DS.
For details, read the descriptions about the N-8640DS in the
