Instruction
For installation:
The product is intended to be installed by skilled technicians. For installation, please contact a system integrator or
IDK. Improper installation may lead to the risk of fire, electric shock, injury, or property damage.
Set the power plug in a convenient place to unplug easily.
Unobstructed access to the plug enables unplugging the product in case of any extraordinary failure, abnormal
situation or for easy disconnection during extended periods of non-use.
Insert the power plug into an appropriate outlet completely.
If the plug is partially inserted, arching may cause the connection to overheat, increasing the risk of electrical shock
or fire. Do not use a damaged plug or connect to a damaged outlet.
Clean the power plug regularly.
If the plug is covered in dust, it may increase the risk of firer.

3 Precautions for shipping
The MM / SM model (NJR -04HD-MM / SM) has an SFP+ module that make it vulnerable to damage caused
by mishandling during shipment if it is improperly packaged.
If, for any reason, you need to ship the NJR, use the carton and cushion which were used at the time of
purchase. If you do not have the carton and cushion, remove the SFP+ module from the NJR and put it in
an antistatic bag with enough cushion. Use the appropriate carton and cushion for shipping.

4 Product Outline
NJR-T04HD (transmitter) / NJR-R04HD (receiver) is a 4-port HDMI network extender with built-in scan
converter. HDMI signals from four ports are transmitted over a pair of fiber optic cables. RS-232C bidirectional
communication and LAN transmission are also supported.
The NJR-T04HD / NJR-R04HD can be used as a 4-input and 4-output matrix switcher or distribution system.
One NJR-R04HD enables 4-screen videowall and even larger number of screens can be used in a videowall
using multiple NJR-R04HDs.
The NJR-T04HD / NJR-R04HD can be used with other IP-NINJAR products. For example, if the
NJR-R01UHD is connected to the NJR-T04HD, 4-port full HD video signals that are input to the NJR-T04HD
can be displayed as 1-port 4K@60 video signals in a sink device.
If the NJR-T01UHD is connected to the NJR-R04HD, 1-port 4K@60 video signals that are input to the
NJR-T01UHD can be divided into four and displayed in four sink devices. (In case the 4K video is protected
by HDCP 2.2, the NJR-R04HD cannot display video signals.)
