Tunnel – Monitoring of 7 meters with pulse outputs via MQTT with alarm to detect the opening of the meter access door.

Scenario details: 7 counters with pulse output need to be monitored. Therefore, a modem with 7 pulse counter inputs is required. The accumulated pulses must be sent to a web platform via MQTT every 60 minutes The meters will be installed in manholes and register boxes which are locked. It is necessary to monitor the […]

Tunnel – Configuration parameters related to analog inputs: “ADC_”

Most MTX modems have one or more analog inputs (0-50V or 4-20mA). The ADC_ parameters allow you to configure the behavior of these analog inputs. For example, you can configure an analog input so that when it exceeds a level, it will send alarm SMS, or send an MQTT message, or make a voice call, […]

Tunnel – Digital I/O and relay configuration parameters: “GPIO_”

Most MTX modems have one or more digital inputs and outputs, and even relays. The GPIO_ parameters allow configuring the behavior of these inputs and outputs. For example, you can configure a digital input so that when it changes state, it will send alarm SMS, or send an MQTT message, or make a voice call, […]

Tunnel – AT Commands Batch Files

Inside the flash memory of the modem is a folder called “atscripts”. Within this folder batch files of AT commands can be incorporated to be executed on certain occasions or by using the command AT ^ MTXTUNNEL = file.For example, if a “miscommands.txt” file is found inside the “atscripts” folder with the content: AT^MTXTUNNEL=SETIO,0,1PAUSE 5 […]
