Active RS232 to RS485/RS422 converter,converter rs232 to rs422/485 serial device server
1.Introduction
Compatible with the Recommended Standards of RS-232C, RS-422 and RS-485, UT-208 photoelectric isolation interface converter can convert the single-ended RS-232 signal into balance differenced RS-422 or RS-485 signal. The built-in photoelectric isolator can provide an isolation voltage of as high as 2500Vrms. Also, there is a rapid transient voltage suppression protector for protection of RS-422/RS-485 interface with advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) technology adopted. Under normal conditions, the TVS tube is in the state of high resistance.
