Isolated USB to RS485 converter for connecting computers, industrial PCs and engineering tools to RS485 field devices through A, B and GND terminals.
The page is written for engineering companies, system integrators, device manufacturers and B2B project procurement teams.
Use the converter between a computer and an RS485 field bus. Plan commissioning around the actual controllers or acquisition modules on the bus; the converter itself is not a load-switching relay.
Input modules collect contacts and equipment states; they do not drive loads. Select by input count and cabinet layout, and add an output controller when equipment switching is required.
View product detailsThe wall panel provides local operation and scene selection; relay controllers switch the loads. Plan panel positions, key count and circuits before adding network control or dimming.

The converter links a computer’s USB port to RS485 controllers, sensors, meters or IO modules through A, B and GND terminals. Configuration software, serial tools or project applications then communicate with the field device. The converter supplies the physical interface; the software and device protocol determine the available operations.
First establish the serial connection and match baud rate, parity and device address. Then read states or measurements using the relevant Modbus or proprietary protocol, checking data type, units and scaling. Unique addresses and individual device verification help distinguish interface problems from protocol or measurement mapping issues.
Use USB for local engineering work or a fixed computer-based acquisition application. Distributed unattended sites can use an RS485 gateway or a controller with Ethernet or 4G. Verify one device and its point table on the engineering computer first, then apply the corresponding protocol configuration to the permanent integration system.
No. It converts the USB/RS485 interface. The software must use the device protocol, address and serial settings.
Yes, when they provide the corresponding RS485 interface. Available data depends on the device protocol and software support.
