Rack Mounting
Important:
When installing the unit in the rack without turning the power of the unit off, activate the HDD safety mode. (Refer to page
34 for further information.)
Important 
• Do not install the unit above an appliance which generates heat such a power amplifier. When installing the unit below a
heat-generating appliance, install it below the appliance with a space equivalent to about 1 unit (44 mm {1.73}) separating
them. 
• Keep the temperature in the rack below +45 °C {113 °F}. It is recommended to install cooling fans or equivalent equipment
to keep the temperature in the rack below +30° C {86 °F}.
1. Remove the four rubber feet from the bottom of the unit
using a flathead screwdriver. 
2. Place the provided rack mounting brackets on both
sides of the unit and tighten with the four provided
screws. 
3. Install the unit with the rack mounting brackets in the
rack by using four rack mounting screws.
Cautions:
• Make a space of 1U (44 mm {1.73}) above and below
the unit for ventilation.
• Keep the temperature in a rack below 45 ˚C {113 ˚F}.
• Install a fan in the rack when the ambient temperature is
above 30 ˚C {86 ˚F}.
• Do not block the ventilation openings or slots on the
cover to prevent the unit from overheating.
Remove the rubber feet.

Connections
The following are descriptions of how to connect the unit with PCs, cameras and an optional extension unit.
Required devices and cables vary depending on how to connect them. Before starting the connections, check the required
devices and cables for your environment.
The connection should be done in the following order:
PC →Cameras →Extension unit
Connection Type
Mode B 
(Direct connection example: When using hubs)
Connect cameras and PCs using the CAMERA port and the client PC port on the rear of the unit respectively as shown in the
illustration below.
Images (video signals) from cameras will be supplied (input) to the CAMERA port, and the supplied images will be transmitted
(output) to PCs. 
Important:Do not connect PCs to a network to which the CAMERA port is connecting. Otherwise, transmission efficiency may
be down.
Do not connect any camera to a network to which the client PC port is connecting for the same reason.

Connection between cameras and PCs
When connecting the unit and PCs through a hub, use a LAN cable to connect between the unit and a hub.
Cameras should also be connected through a hub using LAN cables.
Important:When connecting the unit and a PC directly without using a hub, connect them using a cross LAN cable.
Connection Example

Note:When using a router, MPEG-4 images sometimes may not be displayed. Refer to the network administrator for how to
configure the settings of the router.

Connecting with Extension Unit
Up to 6 extension units can be connected with a single network disk recorder.
Use the dedicated cable to connect between the external storage (EXT STORAGE) connector on the rear of the unit and an
extension unit.
Important:
• Use only the dedicated cable provided with an optional extension unit when connecting the unit and an extension unit.
• Fix the cables with this cable clamp to prevent disconnection or unstable connections that may cause recording failures or
an unstable system.

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.

 How to Use the Terminals of the ALARM/CONTROL Connector
These terminals are used for emergency recording, auto time adjustment, taking measures against power outages, and when
installing a buzzer, a lamp, or similar alarm device.
The terminal pin array and connections are shown below. The connector used should be compatible with the pin configuration.
Pin Configuration
The pin array is different from other disk recorders. Make sure that
the connection is correct referring to the following.

							Connection for emergency recording
When the external switch is turned ON, emergency recording will be started.
Recording time and recording rate for emergency recording differ according to the settings of Emergency REC of
Recording on the SETUP MENU. (Refer to the Setup Instructions (PDF).)
Connection for external recording changeover
When the external switch is turned ON, the recording program changeover is affected for recording.
The recording program can be set by selecting EXT for Time Table of Schedule on the SETUP MENU. (Refer to the Setup
Instructions (PDF).)
Connection for the Auto Adjust Time function
• When Auto Adjust Timeof Time & Date of System on the SETUP MENU is set to MASTER
Time Adjust Output becomes available and the clock of this unit can be applied to other units.

• When Auto Adjust Time of Time & Date of System on the SETUP MENU is set to SLAVE
Time Adjust Input becomes available. When a signal output from other equipment is supplied to the time adjust I/O terminals
between 00 minutes 00 seconds and 14 minutes 59 seconds every hour or between 45 minutes 00 seconds and 59 minutes 59
seconds every hour, the clock will be set to 00 minutes 00 seconds of the closest hour.
Example:
Signal is supplied at 2:50:00 (hour:minute:second)pm →Set at 3:00:00 pm
Signal input supplied at 3:14:45 pm →Set at 3:00:00 pm
Signal is supplied at 3:20:00 pm →Time will not be adjusted.
Important:
• When “SLAVE is selected, the auto time adjustment function works differently depending on the recording status as fol-
lows:
*1: When event recording is performed on any camera channel
When no recording is being performed
When manual recording is being performed
When schedule recording is being performedThe clock will be adjusted.
When event recording is being performed 
*1
When emergency recording is being performedThe clock will not be adjusted.
