Note: The following modem sharing options are available, but N-Tron does not provide technical support for using third party software with the 102RAS (N-Tron also does not provide any software for this use).

If you are using your 102RAS for dial-out, you will have to select one of the Modem Sharing options and select the Country Code. With any of the Modem Sharing options, the TCP port number used to access the modem is 7000. Modem Sharing with authentication means a login prompt will be issued to the socket when it is opened. The opener of the socket must provide appropriate credentials before access is given to the modem. If RAW is also selected – support for RFC 2217 (com port control vial Telnet) will be disabled.

Modem Sharing – No Authentication - Immediate access is given to the modem.

Modem Sharing – Local Authentication - A valid set of credentials, defined in the Local User data base, is required before access is granted.

Modem Sharing – Radius Authentication - A valid set of credentials, defined in the Radius User data base, is required before access is granted.

Modem Sharing – Raw Mode with No Authentication - User data is treated “as is”, without interpretation, and no authentication is required.

Modem Sharing – Raw Mode with Local Authentication - User data is treated “as is”, without interpretation, and a valid set of credentials, defined in the Local User data base, is required before access is granted.

Modem Sharing – Raw Mode with Radius Authentication - User data is treated “as is”, without interpretation, and a set of credentials, defined in the Radius User data base, is required before access is granted.

Caution: Modem sharing is accomplished by implementing a Telnet interface to the 102RAS’s embedded modem. Secure the access to the port via a firewall or IP filter settings to prevent unauthorized use of your modem resource.

Authentication

This page shows the current Authentication configuration of the 102RAS.

Authentication Setup

Remote Host Address

Radius Server Address 1 and Port

Radius Accounting Address 1 and Port

Secret

If your database for user credentials resides in the Local User Database on the 102RAS, then accept the default – “local”. If your user database resides on a Radius Server, then click on the down arrow and choose radius.

If modem usage is RAS, enter a static IP Address in the Remote Host Address window which will be assigned to the dial-in user. This Remote Host Address has to match the network scheme of the 102RAS.

102RAS specifications

The N-Tron 102RAS is a high-performance industrial Ethernet switch designed to meet the demanding needs of various industrial applications, including manufacturing, oil and gas, transportation, and utilities. One of the standout features of the 102RAS is its rugged design, enabling it to thrive in harsh environments where temperature fluctuations, dust, moisture, and vibration are commonplace. The switch operates within a wide temperature range, typically from -40°C to 70°C, ensuring reliable performance in unconditioned spaces.

Built to support real-time networking, the N-Tron 102RAS utilizes advanced Ethernet technology to deliver data with minimal latency. With a robust Layer 2 switching capability, it possesses the ability to efficiently manage and forward Ethernet frames between connected devices, ensuring seamless communication across the network. Featuring up to 16 Gigabit Ethernet ports, the 102RAS caters to a variety of network configurations, allowing for extensive connectivity options.

The switch is equipped with Power over Ethernet (PoE) capabilities, enabling it to deliver power to compatible devices directly through the Ethernet cables. This feature simplifies the installation of devices such as IP cameras, sensors, and access points, eliminating the need for additional power supplies and reducing clutter in the industrial environment.

Another important technology integrated within the N-Tron 102RAS is its support for various network protocols, including VLAN, Quality of Service (QoS), and Rapid Spanning Tree Protocol (RSTP). These features enhance network performance and reliability, providing the ability to segment traffic, prioritize important data packets, and quickly recover from network outages.

In terms of security, the 102RAS is designed with several measures to protect data integrity and access. It supports advanced network security protocols, including access control lists (ACLs) and 802.1X port-based authentication, ensuring that only authorized devices can connect and communicate over the network.

Overall, the N-Tron 102RAS is an exceptional choice for industries requiring a dependable and efficient Ethernet switching solution. Its rugged construction, advanced networking technologies, and rich feature set make it a versatile solution for ensuring uninterrupted industrial operations. Whether upgrading existing infrastructures or deploying new systems, the 102RAS is poised to meet the challenges of modern industrial networking.
