Connection of an extension unit
Up to 3 extension units (optional) can be connected to a single recorder. Use the dedicated cable (provided with the extension
unit) to connect between the extension unit and the recorder.
When connecting multiple extension units (WJ-HDE400/G) or when newly adding extension units, connect as follows. Refer also
to the operating instructions of the extension unit.
Important:
• Make sure to use the dedicated cable provided with the extension unit to connect.
• Fix the cable provided with the extension unit firmly using the cable between the recorder and extension unit. When the cable
is not connected firmly or when it is disconnected, the system may become unstable or recording may fail.
• Do not loop and bundle the cable in a circle.
• When installing the recorder or the extension unit in the rack, make a space of 1U (44 mm) above and below each of them
for ventilation.
