LTE gateway with one FXS telephone line interface, battery backup and serial data interface

• For LTE/UMTS/GSM networks
• One analogue telephone line interface for FXS terminals
• RS232/RS485 and CANBus serial data interface
• Integrated battery backup

With the GSM500.4G gateway it is possible to connect a analogue telephone terminal, or a PBX, directly to the LTE network to realize cost effective routings using the mobile public network. Further to the telephone line also a transparent data communication using RS232, RS485 and CANBus serial interface is provided by the device. Together with the emergency call system many different applications can be planed, like the installation of mobile solutions on construction sites or where the standard telephone network is not available. Also inside high buildings where the installation of this device in the machine room near the roof might be cheaper then running cables up from the basement. Up to 9 ECII FLEX or Helpy emergency call system units can be connected to one GSM500.4G gateway.

No programming is need at all for the installation. A mini SIM card with the PIN code 0000 is enough. The unit will delete this PIN and change it with a random generated one blocking this way the abuse of the card. But alos SIM card without a PIN code can be used. For installation with data connectivity the programming is done easly using SMS. An innovative cloud based application can provide transparente serial data connection just using the internet. On the receiving side no other hardware is required then a PC running the specific VNDNET client application.

The GSM500.4G gateway adapter is delivered with a dual band LTE antenna and a PSU. It is powered with a 230 Vac mains, or using a 10 to 17 Vdc voltage. An emergency power supply with battery backup is integrated in the unit. The battery is tested periodically and an alarm is send using the emergency phone or an SMS if the battery fails the test.
