General overview

WHAT IS NET@XESS

NET@XESS is the acronym of the device functions: advanced Modem/Router Engine. It is in fact a 2/3/4G modem/router with advanced firewall and VPN router functionalities. Simplicity of use is one of its main features; much of the functionality is accessible thru the front panel graphical display and a comprehensive HTTP/SNMP interface. It has been thought to enable remote connectivity to transmitters, encoders, receivers and virtually any equipment present on site connectable thru Ethernet. Think of the advantages: you can access web servers, ftp, SNMP agents, and firmware upgrades of each device tunneling the communication thru a proprietary LAN/WAN or the internet thru a VPN.

Connectivity: enables internet connectivity thru many types of media, it can do load balancing, selection of media to be used (example: use 2/3/4G just in case DSL is not present, or vice versa), this means seamless availability of all devices thru IP at ALL TIMES, with total security, thanks to an internal firewall and VPN engine.

Automation: An internal scripting engine enables onsite monitoring of parameters thru IP. Using a simple scripting language (the ANTScript) enables the user to create elaborated automations which can report complex situations or correct and take action over situations that can occur on-site.

GPIO: An RS485 bus connection is present on the back panel, it can be connected to a large series of probes and I/O's: relay outputs, contact inputs, analog in (0-5v 4-20mA), analog out (0-5v 4-20mA), RF probes, audio probes, quality meters, etc.... All of these measurements can be viewed and alarmed thru SNMP and can be used by the scripting engine. Using I/O can help monitor other onsite equipment like fire alarms, door switches, generators, etc....

Reliability: NET@XESS is a robust system with a main and a backup power supply. All power failures are backed by the internal battery. If more autonomy is needed an external battery can be installed. The external battery is charged by an internal battery charger which keeps it ready for the next power failure. All power status is reported thru SNMP or WEB.

Simplicity: NET@XESS is extremely simple to use and install, thanks to a very accurate manual and a simple web server application, connecting to the internet or your personal VPN can be done in minutes.

Personality: Advanced functionalities are possible thanks to the Linux operating system which enables where requested personalization based on customer requests. Both Hardware and software features can be tweaked to your systems needs.

Main features

Main characteristics are:

  • No annual fees to be paid for VPN or firewall usage.
  • Internal batteries guarantee 8 hours of work, more autonomy with external batteries.
  • Dual LAN enables connection transparency: maintains the same IP addresses of devices onsite
  • The UMTS modem understands automatically the best connectivity and connects automatically to the best cell.
  • On system RS485 and RS232 enables local communication with proprietary I/O
  • The presence of an in-band filter, enhances immunity to harsh RF environments like the ones in transmission sites, enabling ideal connectivity to 2/3/4G networks.

HOW TO USE NET@XESS
NET@XESS can be used in the following ways:

  • 1. MAIN: just 2/3/4G modem/router
  • 2. BACKUP: DSL or satellite modem/router with a 2/3/4G backup

MAIN
NET@XESS works as a unique gateway: it could be the internal 2/3/4G modem or an external gateway as ADSL, IP via SAT, etc...

BACKUP
NET@XESS acts as a 2/3/4G backup to an unavailable main connection. When the main connection fails, NET@XESS restores connectivity to the control center thru the 2/3/4G modem.

CONTROLLER

  • Front panel display with main functions and settings viewed;
  • Main and backup power: NET@XESS can work seamlessly without mains power;
  • SNMP traps in case of malfunctions;
  • SMS and e-mail in case of failures;
  • Different configurations can be set and triggered thru SNMP;
  • Events can be logged;
  • Local automations thru ANTScript®, results can be logged, trigger actions or or sent to control room
  • Management of external I/Os thru RS485-RS232.
DAM08 - Data Acquisition Module

DATA ACQUISITION MODULE – DAM / 104

DAM/104 module adds 8 analog or digital inputs plus 4 relay outputs. On board bridges allow to switch any input form analog to digital.Each circuit feature an embedded voltage converter to completely optoisolate external connections. All inputs have a common ground, galvanically isolated from the RS485 interface BUS.

DGQoS145 - Expansion Board - Relay output module

DGQoS145 module adds 8 relay outputs. Isolation is by default, because the relay switchingcontacts are normally isolated from the coil. The front connector is designed to ease cabling. A 12V 1A, fuse protected, output is available on a separate connector, in case you need to power the inputs switched by the relays. Front LEDs show the status of the board and of any output, plus AUX fuse, hardware problems, board alive, RS485 status both TX and RX.

DGQoS148 - Expansion Board - Optically isolated contact input module

DGQoS148 module adds Nr. 8 optoisolated digital inputs: this means that each digital input can have its own independent ground. The input circuit is designed to accept DC and AC, and the customer can set the input voltage range. A diode bridge frees the user from respecting the input polarity. The front connector is designed to ease cabling. A 12 V 1A, fuse protected, output is available on a separate connector, in case you need to power the inputs. Front LEDs show the status of the board and of any input, plus AUX fuse, hardware problems, board alive, RS485 status both TX and RX.
