Tunnel – Alarms sent by SMS and MQTT message before detection of 220V power loss and before the return of power. Modem with supercap of 1 minute of autonomy
Scenario details: A modem is required to make a transparent IP-RS232 gateway to read a meter. It is also necessary that the modem can inform in case of a power failure, therefore the modem must have enough autonomy to send an alarm when the event occurs For this, a modem with supercap will be used, […]
Tunnel – Data transmission by RS232 via SMS for the control of electronic equipment with proprietary protocols. Use of ALIAS to send nonprintable characters
Scenario details: It is necessary to send a series of commands by SMS to an electronic team, so that it executes actions The communication with the electronic equipment is through a proprietary binary protocol and is done through an RS232 port at 9600.8, n, 1. Therefore, it is necessary to implement an SMS-RS232 gateway The […]
Tunnel – Access the RS232/RS485 serial port of a device via MQTT (for serial RAW data management). Transparent catwalk “RS232/485 – MQTT”
Scenario details: There is a vending machine with an RS232 serial port. We want to connect the RS232 serial port of the vending machine directly to an MQTT platform, where the communications protocol will be implemented. When the reading protocol of the vending machine is implemented in the MQTT platform, the modem must behave as […]
Tunnel – Sending GPS positions, temperature and trailer opening detection for cold chain monitoring
Scenario details: We have a freezer truck transporting frozen goods. We need to install a GPS location device that also allows to monitor the temperature of the truck as well as to control its door For that, the GPS location device must check the GPS location each 60 seconds and send it to a central […]
Tunnel – Serial Cable replacer RS232-4G-RS232 via MQTT
Scenario details: There are 2 RS232 devices (115200,8, N, 1) connected by a serial cable through which data is sent. We want to replace the serial cable with a transparent link RS232-4G-RS232 None of the devices is a PC. They are computers with hardly any intelligence and their internal control programs can’t be modified. That […]
Tunnel – Sending GPS positions in real time to server using TCP socket or HTTP
Scenario details: Some port facilities dispose of vehicles that lack being equipped with a real-ime GPS locating system Being a real-time system it does not need to save GPS locations history to the internal datalogger of the device in order to be sent when it later (as it is done in a conventional fleet control […]
Tunnel – 4G-Serial transparent gateway with SNMP service activated
Scenario details: There are a few hundreds of devices with RS232 port ( configurated at a 115200,8,N,1 and flow control HW). We need to monitor them from a Computer with Internet connection It should be possible to access RS232 devices at any moment, therefore the modem connected to the serial port of the device should […]
Tunnel – Use of MTX-Tunnel as a datalogger. Sending customized and periodic serial data for proprietary protocols
Scenario details: We have a device with an RS232 serial port. Internal registers need to be read and sent to a Web platform every 10 minutes In order to read the records, a proprietary protocol is used. This means that certain bytes of data (proprietary protocol) must be sent via the device’s serial port for […]
Tunnel – Use of MTX-Tunnel as a serial datalogger
Scenario details: We have a device that sends bytes of data, which correspond to a sensor’s readings, via its serial port every 10 seconds. The data will be a maximum of 256 bytes Taking readings every 10 seconds can be excessive for the application. MTX must only take one reading every minute (therefore eliminating 5 […]
Tunnel – Use of MTX-Tunnel as 2G/3G/4G-RS232 gateway and for time synchronization of an external device connected to the modem
Scenario details: A PLC system needs 2G/3G/4G-RS232 gateway to send data to a central server and to receive setting orders The modem must remain in listen mode, waiting for a server connection, in the TCP 20010 port. On the other hand, the PLC can send alarm messages to the server. In the event of the […]
