The RS485 system used for Modbus communication provides a main cable (Bus or backbone), to which all the devices have to be connected with branches (also known as stubs) that are as short as possible. This distance does not include the branches (which must nevertheless be short). You are responsible for paying any taxes, duties, customs fees, and/or VAT charged by your government, as UNITEK has no control over these charges and cannot predict what they may be. Orders shipped outside of the United States may be subject to import taxes, customs duties, fees, and/or VAT (Value Added Taxes) levied by the destination country. International orders will not be refunded for failure to pay import duties, taxes or fees. International duties & taxes may apply and are not calculated at checkout. If you are familiar with RS232, then you may already know a little bit about it. It may sound complicated for those who don’t know what is serial communication, so here’s an explanation.

Now, why don’t companies just use USB or ethernet to transmit data between their devices? Compared to serial communication, USB and ethernet are significantly more complex and expensive. The cornerstone of this complex system is a dependable physical sensing network! This includes speed control using Variable Frequency Drives (VFD) or inverters, as well as controlling simple PLC and HMI network systems. This whole system allows manufacturing facilities to control their devices remotely and also set-up automation. This allowed users in manufacturing facilities to connect larger applications and whole machines with one protocol. Manufacturing facilities use serial communication to link their devices together. Link PC to Serial devices such as printer, label writer, ISDN terminal adapter. In some countries, inserting two cables into the same screw terminal is permitted. 24 AWG solid wires, which are typically used in Cat 5 cables, can break easily when connected to a screw terminal block, which does not provide any strain relief. Easy hookup: Fixed/removable screw terminals, USB, RJ11/12/45, and barrel connectors.

RS485 is also used in performance venues to control lights and systems such as the one shown below. Devices will be linked together via a bus configuration as shown in the picture above. In the WiFi settings (as in the figure above illustrating B), choose "WiFi MQTT". RS485 cable is a type of communication cable commonly used in industrial settings to transmit data between devices. Serial communication is a way to send data. As mentioned, an example of serial communication is RS485. There are different serial communication standards such as RS232, RS422 and RS485. There is a slight surcharge which covers PayPal fees. There are many standards in serial communication and RS485, also known as TIA-485 (-A) or EIA-485, is just one of them. RS485 is however most popularly used in programmable logic controllers and factory floors where there are lots of electrical noise. The final shipping days are according to your local because of COVID-19 guidelines.

For shipping quotes, "Checkout" the item you want to buy, enter your shipping details and the shipping rates will automatically generate based on the item's weight and the delivery location. However, what if you want to use RS485 in your projects but your device only has USB support? But we didn't want to do a "closed system". RS485 is used more industrially where many devices need to be interconnected together for a system. By adding another 2 wires, making it a 4 wires system, it allows data transmission in both directions to and fro devices at the same time, also known as full-duplex. With features like these, the rs485 serial cable is a reliable choice for applications requiring robust and long-distance data transmission in challenging environments, such as industrial automation and building control systems. Now you can stock just one adapter to fill all your legacy "RS" serial interfacing plus provide a low level TTL control interface. This cable can be used between two RS485 splitters or between an i9/i8/i80 and a RS485 splitter.
