How to set up an alarm system with NMS

NMS PC software V 2.0.13

SATELLINE-3AS NMS introduces SATEL’s new concept of remotely manageable radio modems. In addition to ordinary communication functions it exhibits configuration through radio, efficient diagnostics tools and accumulation of operation statistics data. The management and surveillance of a network of 3AS NMS radio modems is effected through the Master Station connected by a serial interface to a PC with dedicated Network Management software. Long-term logs of the operational data on the SATEL NMS PC facilitate follow-up of trends and regularly occurring events. The Network Management System provides easy configuration of the network and advance indication of faults, for maximum reliability, labour-saving maintenance work and efficient system management.

The NMS radio modems monitor the condition of the radio connection, strength of the signal (RSSI) and the voltage level of the power source as well as the inside temperature of the modem, on a continuous basis. The information is transmitted to the SATEL NMS PC, where it is stored and displayed as logs and trend data. With the help of the graphical display of the network available at the SATEL NMS PC, the user can conveniently configure, add or remove radio modems without need of a terminal, as well as draw message routes and set repeater links.

The Network Management System offers the user several significant benefits, including

  • Enhanced reliability, through advance indication of anticipated faults and failures
  • Reduced configuration and maintenance costs, through remote configuration
  • Efficient network development tool
  • Flexibility in adapting to customer protocols and applications
  • A SATELLINE-3AS NMS network provides a working solution to a large variety of wireless data communications applications. It is particularly well suited for frequently changing networks as well as for applications requiring utmost reliability, thanks to efficient monitoring of the signal condition and flexible use of alternative routing. Remote, continuous monitoring of the voltage level of the power source as well as the temperature of the radio modem provide early indication of and possibility of avoiding anticipated problems.

This system requires a specific NMS interface which connects the modem to your Windows.  Remember to specify that you want NMS capability at time of order. Unfortunately this system is not backward compatible with pre May 2005 modems.
