The serial RS232 to RS485 converter and RS232 to RS422 converter units, also called serial converters, are small electronic devices used to convert a serial RS232 signal, (for example the COM port in older computers) into either RS485 or RS422 signals. After connecting as for point B, in the Settings it is possible to define a name for the device, and if the reading periodicity is less than 250 minutes, rs485 cable you can set an interval of hours in which the reading is not carried out / transmitted (for example you can disable the night). 2) the GSM version also allows you to indicate a possible PIN (leave blank if there is no PIN) and the operator's APN (possibly you can search for it on Google). The probe is available with 0.8m or 3m cable; and possibly can be replaced by anyone with good dexterity. It has a special capacitive sensor designed by us, efficient and of good precision, waterproof, resistant to oxidation and not subject to variations due to salinity and soil composition: better than this there are only the "extraction pressure" sensors (which we do not propose because they are not durable and also the sensor alone costs hundreds of euros).

We tried to build an organic system so that whoever gets a TXtemp, TXsoil sensor or a bridge for RS232 or ModBus sensors and devices like TXdata can immediately use them without wasting time in configurations (and we also took the opportunity to insert some things into our system some "extra" not foreseen by the standards!). If there are several sensors near and/or other data to be transmitted via GSM, it is more convenient to use Standard / RF versions supported on a concentrator or controller such as RXTXeasy GSM so you will be able to use one single SIM. If the network host machine fails to send data normally, consider configuring network heartbeat packet verification. I tried connecting it directly to the computer either with a normal network cable or with a crossover cable but the web page doesn't open. Use a 485 to USB serial cable, connect it to the interface of the 485 device and the computer's USB port, assign a COM port on the computer, open serial debugging assistant software, set the serial port parameters consistently, input the corresponding COM port, and monitor the data from the 485 device. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet.

Basically, therefore, they can be used with RXTXeasy GSM or DisplayRX or ControlHUB.. TXSoil can transmit the humidity to a Web server or to a VisualVision's display / concentrator such as DisplayRX or ControlHUB or RXTXeasy GSM - with adjustable interval, remaining for the rest of the time in standby with very low consumption. 2) right under WiFi settings, instead of WiFi TX to Hub / DisplayRX / RXeasy, choose the other settings and write your server / script URL. This with WiFi transmission for the Standard version, and in the RF version also with radio transmission at 433MHz (covering longer distances and with less battery consumption thanks to special optimizations). It does not support Modbus transmission.

A T- --B; Check if the instructions sent to 485 are correct; Are there proper responses from 485 after sending correct instructions? Could I have detailed instructions on WIN 11? We have also included the most widespread industrial standards, HTTP and MQTT, so that our elements can be used in any automation.

For example, there can be a device that measures temperature and another device to measure humidity connected to the same cable, both communicating measurements to the same computer, via Modbus. It is interesting to measure the humidity of the ground, but we have also thought about other things; and then we have TXtemp to measure the temperature (one of the uses of TXtemp is in association with SuperClock), and for practically any type of measurement we have TXdata (RS232, RS485 ModBus) - which can be connected to thousands of existing third-party professional RS232 or ModBus meters (and there is something for all needs: temperature and humidity meters, anemometers, voltage meters, energy, light meters, water meters, presence sensors, brightness sensors, soil humidity sensors, etc. ; practically all professional meters are available in ModBus or RS232 standard; and not just meters). Only one driver may be in the on at the time. This connection may be used to limit the common-mode signal that can be impressed on the receiver inputs. Two wire telephone cables will not function because in that case the ground signal levels on both sides will be floating. Interoperability of even similar devices from different manufacturers is not assured by compliance with the signal levels alone.
