Fret not. There are tools available that can be used to convert your USB ports to RS485. There are many standards in serial communication and RS485, also known as TIA-485 (-A) or EIA-485, is just one of them. Their main difference boils down to one having only support for RS485, while the other one supports RS232 and TTL as well. Developed by Modicon, Modbus enables different devices from different manufacturers to be integrated into the main system. Devices (Device 1, Device 2, Device N) are connected in series, forming a daisy chain topology.

In theatre and performance venues, RS-485 networks are used to control lighting and other systems using the DMX512 protocol. In this situation, bandwidth can be used for almost 100%. There are other implementations of RS485 networks where every node can start a data session on its own. Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments. Through appropriate programming and configuration settings within the central control system, relevant flow measurement data can be read from the flowmeter. The flowmeter leverages RS485 for signal transmission and is connected in a serial configuration with the customer's central control system. Devices utilizing RS485 can communicate with central control systems using communication protocols such as Modbus and ASCII. In most cases, RS485-based devices can employ communication protocols such as Modbus and ASCII to establish communication with a central control system. What made it such an advancement over RS232 was the fact that it could transmit not only a single device to device transmission, but also a communications bus to connect multiple devices at once.

However, Arduino and Raspberry Pi hobbyists also use it for some of their projects when multiple peripherals need to be linked to the board. However, in a full-duplex setup, they are limited to a master and slave communication where slaves cannot communicate with each other. However, what if you want to use RS485 in your projects but your device only has USB support? The aforementioned SenseCAP Sensor Hub at its stock has only 4 ports to connect RS485 sensors despite it being able to support up to 32 different RS485 sensors. It is the reason why RS485 is so popular with computers, PLCs, micro controllers and intelligent sensors in scientific and technical applications. Grove sensors to MODBUS RS485 industrial-grade sensors. There is a whole plethora of SenseCAP industrial-grade sensors, and this is just one of the many! Clueing in from its name, this is a USB to RS485 converter with industrial-grade features. Best known for the simplicity of usage it provides, it also features embedded circuits protection features such as lightning-proofing, resettable fuse, ESD protection and TVS diode.

RS232 is without doubt the best known interface, because this serial interface is implemented on almost all computers available today. RS232 could only handle one. It comes in two versions, one with DC only, and another with a built-in rechargeable battery. RS485 has many advantages over other standards, especially when it comes to applications in noisy industrial environments. It comes with temperature compensation to compensate for the temperature changes for a more precise reading. Ultimately, it can be thought of in a way that serial communication is more made for this usage as compared to the common USB and ethernet. This connection may be used to limit the common-mode signal that can be impressed on the receiver inputs. Sig- line. The RS485 receiver compares the voltage difference between both lines, instead of the absolute voltage level on a signal line. Shifts in the ground level can have disastrous effects. Modbus devices communicate using a Master-Slave technique where only one device (the Master) can initiate transactions (AKA queries). As mentioned, RS485 is used to link devices instead of other means as it provides significant advantages. These advantages compared to other alternatives made RS485 popular and used in a widespread amount of instances.
