The BT232/485/422 fiber optic modem is a multifunctional RS232/485/422 interface to fiber optic modem. It is the best choice for connecting remote terminal units (RTUs) to hosts (HOSTs) or distributed data acquisition system (SCADA) controllers. This product uses optical fiber as the transmission medium, which improves the system transmission performance and effectively avoids the threats of lightning strikes, surges, and electromagnetic interference to communication equipment in harsh environments.
