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.

7.2.1.3 Limit on the number of TCP-IP connections and port overload management

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.
