Tunnel – DATALOGGER. Telemetry (digital and analog inputs) sent periodically to the web server via HTTP (via JSON object) + transparent IP-RS232 gateway for remote access to the RS232 device.
Scenario details:
- 3 digital inputs and 2 analog inputs must be sent to a web server via HTTP request using a JSON object
- The MTX will collect digital and analog data every 10 minutes, sending it to the web server via HTTP request using a JSON object. If there is no 4G/3G/2G coverage or the web server is not available, no readings should be lost and the MTX modem must store the read records (a maximum of 1000 records) in its flash memory to try to send it when there is coverage
- Likewise, it is necessary to be able to activate a transparent IP-RS232 gateway in parallel to the telemetries for the remote reading of a device with RS232 serial port at 9600.8, N, 1. For convenience there is a SIM with a fixed IP address in the MTX modem
- The modem must also send its status (coverage, IP, etc.) periodically (every 10 minutes) to the web server via HTTP request
Solution: MTX-Tunnel firmware + MTX-IOT-S [4-N]

Details:
-
Remember that you have the I / O descriptions of the MTX model in ANNEX 10 of this manual. Be sure to configure the microswitches appropriately to read voltage or current on the AD0 and AD1 inputs of the MTX modem
-
The MTX modem will send the value of its digital and analog inputs, the Logger data, every 600 seconds (10 minutes). In the HTTP request that the MTX modem will make to the Web server every 10 minutes, a JSON is included with the following format shown through an example
{“IMEI”:354033091487838,”TYPE”:”IOS”,”TS”:”2020-02-08T15:35:07Z”,”P”:”ID00001”,”IO0”:1,”IO1”:0,”IO2”:0,”IO3”:0,”IO4”:0,”IO5”:0,”IO6”:0,”IO7”:0,”IO8”:1,”AD0”:1200,”AD1”:4850}
Where:
IMEI: indicates the IMEI of the modem
TS: timestamp of when the data was read in the modem
TYPE: frame type. In this case it is “IOS”
Q: the field indicated in LOGGER_password
IOx: digital input/output x. see Annex 10 for more information. x = 0… 8
ADx: analog input 1 and 2 (values from 0 to 50,000 mV)In the same way, the modem status data, DNS frames, sent every DNS_period seconds to the web server via HTTP, will have the following format:
{“IMEI”:”354033091487838”,”TYPE”:”DNS”,”TS”:”2020-02-08T10:23:13Z”,”P”:”ID00001”,”IP”:”95.124.213.236”,”CSQ”:18,”TECH”:”4G”,”VER”:”11.00”,”AUX”:””,”MOD”:”MTX-IOT-4G-S”,VCC:12000}
Where:
IMEI: indicates the IMEI of the modem
TS: timestamp with modem time
TYPE: frame type. In this case it is “DNS”
Q: the field indicated in DNS_password
IP: current IP of the modem
CSQ: RSSI (0… 31)
TECH: technology (2G, 3G, 4G)
SEE: FW MTX-Tunnel version
AUX: auxiliary field defined in DNS_aux
MOD: model of the modem (MTX_model field)
VCC: MTX supply voltage (in millivolts)
Geben Sie den Verbindungsmodus „ethernet“ oder „modem“ ein:
Stellen Sie bei einer Ethernet-Konfiguration sicher, dass die IP-Parameter mit dem Serverzugriff entsprechend der lokalen Netzwerkkonfiguration des Hubs kompatibel sind. Bei einer Ethernet-Verbindung muss die Konfiguration mit der lokalen Netztopologie des Hubs kompatibel sein, damit dieser auf die Server zugreifen kann. Diese Konfiguration erfolgt über die Konfigurationsseite „Networks“ (siehe Kapitel 3.2.2.3: „Netzwerke (Networks)“).
Bei einer Modemverbindung muss das Modem korrekt konfiguriert sein, bevor eine Verbindung hergestellt werden kann. Diese Konfiguration erfolgt auf der Konfigurationsseite „Modem“ (siehe Kapitel 3.2.2.4: „Modem“).
Die minimal zu konfigurierenden Serverparameter sind folgende:
Diese Felder müssen konfiguriert werden: „Interface“, „Type“, „Server type“, „Address“, „Port“, „Login“ und „Password“.
In den übrigen Feldern können die Standardwerte beibehalten werden, solange die Verzeichnisse zuvor korrekt angelegt wurden. Weitere Einzelheiten siehe Kapitel 3.1.2: „Konfigurationsdateien“.
Warten Sie. Der Hub startet nach ein paar Augenblicken mit der Werkseinstellung neu.
