The NB1600 WLAN from NetModule is an industrial router that can be configured as a WLAN access point or as a WLAN client. It combines the functionalities of a wired router with wireless network connectivity and is designed for use in industrial environments where reliability and flexible network configuration are required. The device enables wireless internet access for other end devices and supports the setup of multiple separate WLAN networks via the Multi-SSID function. This feature is particularly useful for separating different user groups or security zones.

Applications

The router is suitable for industrial applications such as machine control, building automation, remote monitoring, or networked production environments. The combination of WLAN functions and industrial interfaces makes it flexible to use, for example, in factories, logistics centers, or outdoor areas where wired connections are not practical. Support for Multi-WAN and Least-Cost Router functions enables the use of multiple internet connections, with automatic switching to an alternative connection in case of failure.

Functions and Equipment in Detail

The NB1600 WLAN features two Ethernet ports that can be individually configured as LAN or WAN ports. The two LAN ports can either be operated as separate networks or combined into a switch via a network bridge. In WAN mode, IP configuration can be static, via DHCP, or via PPPoE. The integrated SDK environment allows programming of the device using a simple scripting language, with a wide range of example scripts available. The RS-232 serial interface can be used as a serial device server or as a system console and can also be controlled from the SDK environment.

Technology Explained Simply

The two isolated binary inputs and two relay outputs allow connection to sensors and actuators. The logic for these interfaces is implemented by the user in the SDK environment, enabling individual control of external devices. The USB port is used for quick configuration and firmware updates via a memory stick. Alternatively, it can be configured as a device server to make external USB devices available on the network. The router firmware supports common VPN technologies such as OpenVPN, IPsec, and PPTP, with both client and server modes supported. Setting up VPN tunnels between two NetModule routers is possible via a Public Key Infrastructure and can be done in a few steps.

Compatibility and Accessories

The device is equipped with a wide range of network functions, including DHCP server, DNS proxy server, DynDNS agent, SNMP agent, Telnet/SSH server, web server, email client, and SMS client. The user interface is accessible via a web interface or command line. The SNMP interface allows integration of the router into a network management system, facilitating monitoring and control within a larger network. The functionalities are compatible with common network protocols and standards, enabling integration into existing IT infrastructures.

Mounting and Installation

Installation is performed via the integrated user interface, accessible through the web interface or command line. Configuration of WLAN functions, Ethernet ports, VPN connections, and SDK programming is done through these interfaces. Device configuration can also be performed via the USB port using a memory stick, simplifying maintenance and updates. The serial interface also enables direct console control, which is useful for maintenance tasks or when network connectivity is unavailable.

Advantages in Operation

The NB1600 WLAN offers high flexibility through its configurable ports and SDK programmability. Support for Multi-WAN and automatic switching ensures high network connection availability. The integrated sensor and actuator interfaces enable direct control of industrial devices, allowing the device to function as a central interface in networked systems. Support for VPN technologies ensures secure communication, especially when connecting locations over the public internet. SNMP support facilitates integration into existing network management systems, making monitoring and maintenance more efficient during operation.
