Introduction Introduction Overview The Omega Engineering OMG-COMM+232.PCI is a two channel PCI Bus serial I/O adapter for the PC and compatibles. It provides two RS-232 serial ports supporting data rates up to 460.8K bps. The OMG-COMM+232.PCI works seamlessly with the standard operating system serial driver. UART upgrades are available providing 32 and 64 byte FIFOs. What’s Included The OMG-COMM+232.PCI is shipped with the following items.
Card Setup Card Setup Address and IRQ selection The OMG-COMM+232.PCI is automatically assigned I/O addresses and IRQs by your motherboard BIOS. Only the I/O address may be modified by the user. Adding or removing other hardware may change the assignment of I/O addresses and IRQs. Clock Modes The OMG-COMM+232.PCI employs a unique clocking option that allows the end user to select from divide by 4, divide by 2 and divide by 1 clocking modes. These modes are selected at Headers J1C through J4C.
Card Setup DIV1 DIV2 DIV4 To double these rates up to a maximum rate of 230.4K bps place the jumper in the divide by 2 (silk-screen DIV2) position. Figure 2 - Clocking Mode 'Divide By 2’ Baud Rates and Divisors for the ‘DIV2’ mode The following table shows some common data rates and the rates you should choose if using the adapter in the ‘DIV2’ mode. For this Data Rate 1200 bps 2400 bps 4800 bps 9600 bps 19.2K bps 38.4K bps 57.6 K bps 115.2 K bps 230.

Card Setup DIV1 DIV2 DIV4 To select the maximum data rate (460.8K bps) place the jumper in the divide by 1 (silk-screen DIV1) position. Figure 3 - Clocking Mode 'Divide By 1’ Baud Rates and Divisors for the ‘DIV1’ mode The following table shows some common data rates and the rates you should choose if using the adapter in the ‘DIV1’ mode. For this Data Rate 1200 bps 2400 bps 4800 bps 9600 bps 19.2K bps 57.6 K bps 115.2 K bps 230.4K bps 460.

Technical Description Technical Description The Omega Engineering OMG-COMM+232.PCI provides a PCI interface adapter with 2 asynchronous serial ports providing a versatile interface for modems, printers and plotters. The OMG-COMM+232.PCI utilizes the 16550 UART. This chip features programmable baud rates, data format, interrupt control and a 16-byte input and output FIFO. Also available as an option is the 16C650 UART that provides a deeper FIFO (32 bytes) and enhanced clocking features.
Technical Description polling’. This method required the interrupt service routine to ‘poll’ or interrogate each UART as to its interrupt pending status. This method of polling was sufficient for use with slower speed communications, but as modems increased their throughput abilities this method of servicing shared IRQs became inefficient. Why use an ISP? The answer to the polling inefficiency is the Interrupt Status Port (ISP).

Appendix A - Troubleshooting Appendix A - Troubleshooting A Serial Utility Diskette is supplied with the Omega Engineering adapter and will be used in the troubleshooting procedures. By using this diskette and following these simple steps, most common problems can be eliminated without the need to call Technical Support. 1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc.
Appendix B - How To Get Assistance Appendix B - How To Get Assistance Please refer to Appendix A - Troubleshooting prior to calling Technical Support. 1. Read this manual thoroughly before attempting to install the adapter in your system. 2. When calling for technical assistance, please have your user manual and current adapter settings. If possible, please have the adapter installed in a computer ready to run diagnostics.
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.
Appendix D - Asynchronous Communications Appendix D - Asynchronous Communications Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends.

Warranty Appendix F - Compliance Notices Federal Communications Commission Statement FCC - This equipment has been tested and found to comply with the limits for Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
WARRANTY/DISCLAIMER OMEGA ENGINEERING, INC. warrants this unit to be free of defects in materials and workmanship for a period of 13 months from date of purchase. OMEGA’s WARRANTY adds an additional one (1) month grace period to the normal one (1) year product warranty to cover handling and shipping time.
