USB to Serial Media Converters offer integral isolation.
February 3, 2009 -
Intelligent and stackable expansion modules, ISC-1210U-I and 1310U-I, connect to PC USB port/hub to provide one RS-232/-422 or one RS-485 serial port. Powered by USB interface, products deliver auto direction flow control on RS-485 and support full-duplex transmission for RS-232/-422. RS-232 standard also supports handshaking signals such as RTS/CTS. Along with 3,000 Vdc isolation, products offer transient suppression (RS-485 data lines) and support baud rates to 115.2 Kbps.

Introduction
The ISC-1210U-I / ISC-1310U-I convert is an intelligent, stackable expansion module that connects to a PC USB port or USB Hub via the Universal Serial Bus(USB) port, providing one High-Speed RS-232/RS-422 or RS-485 serial port(jumperless). The ISC-1210U-I / ISC-1310U-I features easy connectivity for traditional serial devices. The RS-232 standard supports full-duplex communication and handshaking signals (such as RTS, CTS) and The RS-485 control is completely transparent to the user and software written for half-duplex COM works without any modifi cation. The ISC-1210U-I / ISC-1310U-I's Opto-isolators provide 3000 VDC of isolation to protect the host computer from ground loops and destructive voltage spikes on the RS-232/RS-422 and RS-485 data lines. ISC-1210U-I / ISC-1310U-I also offer internal surge-protection on their data lines. Internal high-speed transient suppressors on each data line protect the modules from dangerous voltages levels or spikes. The ISC-1210U-I / ISC- 1310U-I module derives the power from USB port and doesn't need any aid of external power adapter.
