The ComBoard RTS input line controls the driver enable line so the device only talks when it is its turn. The termination also includes pull up and pull down resistors to establish fail-safe bias for each data wire for the case when the lines are not being driven by any device. Ideally, the two ends of the cable will have a termination resistor connected across the two wires. The largest communications range between the TSX08PRGCAB and PLC are up to two kilometers (9600 bps),when external plus terminals an 120 ohm resistance and a 5 VDC power on the RS485 ports (8 pin Mini DIN Male) of the cable. TSX08PRG connect with computer and communicate with Schneider PLC need to install Uni-Telway or MODBUS driver to at first, for using the corresponding various PLC programming software, to realize the operations as upload, download, control and communications. The cable can communicate with TER interface of TSX Premium (57), TSX Micro (37), TSX Nano (07), TSX Naza (08) Twido PLC, and to realize the procedures to upload, download, surveillance and other function such as multi-point communication of MODBUS.

Rs485 is low impedance balanced , so twisting the pair helps with noise immunity as well as reducing the attenuation effect of higher baud rates due to the parallel capacitance of the wires in the cable jacket over the long lengths. Yes, it would work for that too, but 24 awg cable with plenum grade jacket is the standard. The snap switch located on the TSX08PRGCAB programming cable are used to choose a different mode of operation. Immediately after the WiFi settings, below the page, there are the MQTT ones. Works with 4 AA batteries (1.5V, alkaline or Lithium - for outdoor winter use you need to use AA lithium batteries because the alkaline ones suffer from the cold); on request it is also available for working with external 5V power supply. Since the AUX port of the PLC have no power output pins, TSX08PRGCAB can not use this port. 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).

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. There is also the GSM version; especially useful when only one sensor is needed in a remote location where other types of transmission cannot be used. The two values provide a sufficient margin for a reliable data transmission even under severe signal degradation across the cable and connectors. 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). TXsoil is a compact and low consumption sensor that can measure and transmit the humidity of the ground WiFi or RF or GSM. 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. 1) connect etc. as for B. and go to Settings. In the WiFi settings (as in the figure above illustrating B), choose "WiFi MQTT". 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, 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). Now there was certain instances I used STP wire for rs485 because I had a lot of devices connected in a long run chain (DMX512 lighting fixtures). It seems if there is a lot of RFI in the installation, shielded twisted cable can be justified. RS232/RS485 interface cable for Schneider PLC programming,3 meters,with master/slave switch,used for programming communication or other communication such as MODBUS. TSX08PRGCAB can be used for Modicon TSX Series PLC of Schneider and PC or other equipment which provide the traditional RS232 serial port communications.
