Important
• Never use extension cables (locally procured). Be sure
to use the supplied serial cables for connection.
• Physical connections determine the unit number in a
system for each unit. Connect units with the recorder in
numeric order as shown in the figure. For example, con-
nect the sixth and seventh units to the third unit when
five units have been already installed.
• Do not change connections after the system has run.
Otherwise, the recorder will no longer recognize the
extension units as before. You can change connections
only when you can discard all existing data stored in
the units.
• If turning off the power of a unit, none of the connected
following units will work because of interrupted data
transmission.
Note: When the system is connected in a different way from
the figure, a unit number check can be performed on
the HDD SAFETY MODE of the digital disk recorder.
Refer to Setup Procedures.
