7 Preparations
Before using connecting the NJR-CTB, follow the precautions and instructions below.
7.1 Installation
Follow the instructions below when installing the NJR-CTB.
・ Do not place the NJR-CTB on another device directly.
・ Do not block vent holes. To provide adequate ventilation, maintain sufficient clearances around the
NJR-CTB (30 mm/1.18 inches or more).
・ Prepare ventilating equipment to keep the ambient temperature at 40 degrees C/104 degrees F or less. If
inadequately vented, the life of parts may be shortened and operation may be affected.
7.2 Cabling
Follow the precautions below when connecting NJR-CTB to an external devices.
・ Read the user guides of the external devices carefully.
・ When connecting a cable to the NJR-CTB or a compatible product, dissipate static electricity by touching
grounded metal such as racks before handling single cables. Failure to observe this precaution may
result in ESD (electrostatic discharge) damage.
・ Turn off all devices.
・ Be sure to fully seat all plugs and connections and dress cables to reduce stress on connectors.
7.2.1 Connecting LAN cable
The NJR-T01UHD and NJR-R01UHD send broadcast packets through the 10GbE LAN ports periodically for
the purposes of internal system management. If the 10GbE LAN port is connected to an existing network, it
may cause a broadcast storm* and may severely interfere with normal network operation. Contact IDK
before attempting to connect the 10GbE LAN ports of an IP-NINJAR system to any existing network
infrastructure.
*A broadcast storm occurs when a network is overwhelmed by continuous broadcast traffic resulting
in a network meltdown.
During installation, it is important to avoid the creation of network loops. Contact IDK if you require assistance
with network implementation.

The NJR-CTB’s maintenance port supports a maximum of eight simultaneous connections (eight logical
ports). To maintain optimal system accessibility, it is advisable to issue “port-open” and “port-close”
commands before and after command or query strings are issued. This approach enables eight or more
control devices to be effectively interfaced simultaneously and without concern for communication errors. As a
safeguard, the NJR-CTB incorporates a 30-second timeout window for each port. If any port is inactive for
more than 30 seconds, it will be closed automatically.

Note:
If no command is sent from the PC side to the NJR-CTB for 30 seconds, the NJR-CTB automatically
disconnects from that device.
