Divar | Installation Manual | Hardware setup EN | 4-2
Rack mounting
The Divar can be mounted in a 19-inch rack. A rack mounting kit is supplied
with the unit that includes:
• left and right rack mount ears
• four Torx screws with integrated lock washers.
• a Torx screwdriver
Mounting
1. Remove the four Torx screws (two on each side) located near the front panel
on the right and left side of the housing.
2. Attach the mounting ears to each side ensuring that the lip is under the unit.
Use the four Torx screws with lock washers and tighten securely.
3. Install the unit into the rack using the rack manufacturer’s supplied hardware.
When installing the assembly into the rack, be careful not to restrict airflow
around the vent holes located in the side panels or to exceed the recommended
operating temperature.
Camera connections
Connect cameras to the unit using 75-ohm video coaxial cables with BNC
connectors. There are two BNC connectors for each camera. Either connector
can receive a camera's signal. This signal is looped-through (directly connected)
to the other connector, so that you can send the camera's signal to other
equipment. The camera input connectors are auto-terminating, so you do not
need to add a terminator to the output connector if no additional equipment is
connected.
If the camera signal is looped-through to additional equipment, make sure that
the end of the video line is terminated with a 75-ohm termination.
The Divar automatically configures itself as a PAL or NTSC unit. The unit
determines the standard by detecting the signal format of the first connected
camera (lowest camera input number).
Cameras that support the Bilinx communications standard can be directly
connected to the BNC connectors if your Divar version is Bilinx-enabled.
If Bilinx cameras are looped-through to multiple Divars, only one Divar is
allowed to have Bilinx enabled!
