USB to RS485 Converter UC-RS485
*Connecting to Industrial Field buses, remote devices to a latest Computer becomes
difficult due to obsolete of the RS232C ports by Computer Manufactures.
*But with the vast use of equipments with these interfaces needs a connection with PC for monitoring, configuring and working.
*Most of the market available converters are not equipments with proper ESD protection circuits to work longer and with an industry equipment.
*So we have our most suitable converter for both Industrial environment and general usage.
In most case of Windows 10/11 and Linux the driver will be installed automatically when the PC is connected to the Internet.
