Roger UT-2USB USB-RS485 Interface

UT-2USB v2.0 interface enables communication with RS485 devices by means of computer’s USB port. Basically, the interface is dedicated to RACS system but it is installed as virtual serial COM port so it can also be applied in communication with third party devices. If the interface is to be used beyond RACS system then there should be performed tests in order to confirm its suitability in particular scenario of operation. Due to UT-2USB galvanic isolation, the computer is electrically separated from devices connected to RS485 bus and there is no risk of interferences between power supply systems of connected devices caused by equalizing currents.
