Figure 9. Simplified block diagram, loop test for RFL NCM module in NMS mode, installed in a terminal multiplexer.

9.Go to “Setup” on the toolbar in NMS, and select “Communication Preferences”. Check the “Change Advanced Settings” box, and enter the NCM/CM address into the “Assume Communication Works/Comm to node #”. Click “OK”.

10.Check “Read” Icon and check the “Auto Configure” box. Then select Method 3 and then click “OK”. Then click “OK” again and proceed with the read. Commands sent to and responses from the CM (via the NCM) should be evident in the communications window. IN1 (DS1), OUT2 (DS2), IN2 (DS3), and OUT2 (DS4) will illuminate green when data is present at the respective port.

12.Once the Read of the node has concluded, click the NetVw Icon. The node corresponding to the NCM/CM address should be present. Select this node by clicking on it. Verify that the “NCM” module is present in the list.

12.Select “NCM” and click the view button. Verify that all NCM settings are correctly set. (i.e. address passing mode)

13.Disconnect the patch cord from the DS1 EQUIP OUT and DS1 EQUIP IN jacks on the front of the IMUX 2000, and close the front door.

If the above test procedure can be successfully completed, the RFL NCM module is functioning properly. If not, use standard troubleshooting procedures to isolate the problem to the module itself, to another module in the IMUX 2000, or to the T1 or E1channel. If the problem lies in the RFL NCM module, replace it with a spare.

Network Communications Module, RFL NCM specifications

RF-Link Technology has emerged as a significant player in the realm of wireless communication, and one of its standout offerings is the RFL NCM (Network Communications Module). This module is designed to facilitate efficient and reliable data transmission in a variety of applications, making it a versatile solution for both industrial and commercial needs.

The RFL NCM is built on advanced RF technologies that support multiple communication protocols, ensuring compatibility with different systems and devices. One of its main features is its exceptional range. The module is capable of transmitting data over long distances, making it ideal for applications where devices are spread out. This long-range capability is essential for remote monitoring and control tasks, such as in smart agriculture, environmental monitoring, and industrial automation.

Another defining characteristic of the RFL NCM is its low power consumption. The module employs energy-efficient communication methods, enabling devices to operate for extended periods without frequent battery replacements. This makes it particularly useful in applications where power availability is limited or where continuous operation is required without maintenance interruptions.

The RFL NCM supports a variety of communication protocols, including LoRa, Zigbee, and MQTT, providing flexibility for developers and integrators to choose the most suitable technology for their specific applications. Its robust design ensures resilience in various operating conditions, including extreme temperatures and potential environmental hazards like moisture and dust.

Ease of integration is another strong point of the RFL NCM. With extensive documentation and support, developers can quickly incorporate the module into their existing systems. It also features built-in security protocols to safeguard data during transmission, which is particularly important in today’s increasingly connected world where data breaches are a growing concern.

The RFL NCM is not just about performance; it inherently supports scalability, allowing users to expand their network as their needs grow, whether that's adding more sensors to a monitoring system or integrating additional devices in a smart home. This commitment to both performance and adaptability makes the RFL NCM an attractive option for developers looking to harness the power of RF communications.

In summary, the RF-Link Technology RFL NCM stands out due to its long-range capabilities, low power consumption, support for multiple communication protocols, and robust integration features. With applications across various sectors, including industrial, commercial, and residential, this module promises to enhance connectivity and streamline operations in an increasingly wireless world.
