Industrial 1-port USB to 8-port RS-232 serial media converter



ISC-4110U and ISC-8110U are intelligent and compact-size media converters that provide conversion between one Universal Serial Bus (USB) port and 4 or 8 High-Speed RS-232 serial ports. The ISC-4110U and ISC-8110U feature easy connectivity for traditional serial devices. The RS-232 standard supports full-duplex communication and handshaking signals (such as RTS, CTS, DSR, DTR). Internal high-speed transient suppressors on each data line protect the modules from dangerous voltages levels or spikes. ISC-4110U/8110U can derive the power from USB port or redundant power inputs. Therefore, ISC-4110U and ISC-8110U are among the most reliable choices for USB to RS-232 media converter applications.
