Introduction Introduction Overview The OMG-USB-232-1 equips the PC with 1 USB to RS-232 Asynchronous serial port providing a versatile interface for common RS-232 needs (i.e. modem, mouse and plotter). The advantage of this product over more traditional approaches is that it doesn’t require opening the computer case, nor does it require resources such as I/O ports or IRQ’s. It does require a system that supports USB both in terms of hardware and operating system. What’s Included The

Appendix C - Electrical Interface Appendix C - Electrical Interface RS-232 Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard. This standard is defined as the 9-Position Non-Synchronous Interface bet
