Product Details
This industrial USB to 4 - channel RS485 converter is a game - changer. It comes with multiple protection circuits, ensuring a safe and stable operation. With support for multiple systems like Win7/8/8.1/10/11, Mac, Linux, and Android, it offers great versatility. The aluminium alloy case, with its oxidation dull - polish surface and precision CNC process, is not only solid and durable but also well - crafted. It supports both wall - mount and rail - mount installation methods.
Key Features:
- Extends USB to 4 channels of RS485, enabling concurrent and independent communication for each channel.
- Onboard TVS suppresses surge and transient spike voltages, providing lightning and anti - electrostatic protection.
- Resettable fuse and protection diodes ensure stable current and voltage outputs, offering over - current and over - voltage protection and improving shock - proof performance.
- RS485 output terminal has 120R resistors that can be enabled or disabled via a DIP switch.
It can convert USB signals into 4 balanced differential RS485 signals. The transmission rate is stable, with a reliable speed of 1200 - 460800bps. The RS485 transmission distance can reach up to about 1.2km, while the USB transmission distance is about 5 meters.
For more information, check the WIKI at www.waveshare.com/wiki/USB_TO_4CH_RS485. The package includes 1 USB TO 4CH RS485 unit and 1 approximately 1.2m USB type A to type B cable.
Using this converter is easy. First, connect the USB cable from your device to the converter. Then, connect the RS485 devices to the appropriate channels on the converter. You can choose to mount it on the wall or a rail according to your needs. When using, make sure your system is one of the supported ones like Windows, Mac, Linux, or Android.
Here are some important notes. Avoid exposing the converter to extreme temperatures, humidity, or strong magnetic fields. If you encounter any power - related issues, the resettable fuse might have tripped. In that case, just wait for it to reset. Don't try to force - reset it manually.
For maintenance, keep the converter clean. You can use a dry, soft cloth to wipe the aluminium alloy case. Check the connections regularly to make sure they are secure.
