triangulo  MTX-65ULP + MTXTunnel   (Ultra low power GSM/GPRS modem)
Main Hardware Features:

  • GSM/GPRS quad-band modem
  • 2.5uA consumption in sleep mode
  • 6VdC-10VdC power supply
  • Led indicates gsm/gprs connection status
  • 2 RS232 serial ports
  • 4 digital inputs
  • 2 analog inputs 0-2.4V


Main Software Features:

  • Up to 2 GPRS – RS232 simultaneous transparent gateways to control 2 serial devices with a single modem and SIM card
  • Automatic low power output at specific times.
  • TCP Server, TCP Client and UDP modes.
  • Permanent GPRS connection or on demand (missed call, SMS, time, GPIO…)
  • Automatic monitoring of the GPRS connection status, restarting it if necessary.
  • Digital outputs with remote control (via GPRS, GSM, SMS, Serial …)
  • TCP modbus/ RTU modbus gateway.
  • Datalogger and automatic reading of Modbus devices (PLCs, probes, …) sending data automatically to a Web server via JSON.
  • Sending telemetries (digital/analog inputs) to a Web server via JSON.
  • WebServer integrated for remote MTXTunnel operations / configurations
  • Telnet integrated for remote MTXTunnel operations / configurations.
  • SMS alarm when there is a change in digital inputs.
  • GPRS alarm when there is a change in digital inputs.
  • Total control via SMS (device settings, digital inputs/outputs, checking coverage, resets, …)
  • DynDNS
  • Private DNS (the modem can send its current IP to the server every time it changes)
  • Firewall to avoid unauthorized access.
  • GPRS-I2C/SPI, HTTP/RS232, SMS-RS232/RS422/RS485 tunnels.
  • SSL Security.
  • GSM cell tracking.
  • API for third party application integration.
  • Metering Solutions for Meter Reading. Accepts GSM calls and GPRS connections, giving preference to GSM calls (to give priority to the energy operator: Iberdrola, Endesa, …)
