Introduction Omega Engineering OMG-COMM8-A Page 1 Introduction Overview The Omega Engineering OMG-COMM8-A provides the PC with eight RS -232 asynchronous ports. The OMG-COMM8-A allows for connection to any device utilizing the RS -232 electrical interface, such as modems, data -entry terminals, and plotters.
Introduction Omega Engineering OMG-COMM8-A Page 2 To install the OMG-COMM8-A using factory default settings, refer to the Installation section of this manual.
Card Setup Omega Engineering OMG-COMM8-A Page 3 Card Setup The OMG-COMM8-A contains several jumper straps that must be set for proper operation. Address Selection The OMG-COMM8-A occupies 64 I/O locations and can be addressed two different ways.
Card Setup Omega Engineering OMG-COMM8-A Page 4 The following illustration shows the correlation between the DIP-switch setting and the address bits used to determine the base address. In the example below, address 280 (Factory Default) is selected as a base.
Card Setup Omega Engineering OMG-COMM8-A Page 5 IRQ Selection The OMG-COMM8-A has an interrupt selection jumper that corresponds to each port that may have to be set prior to use. The software you are using with the board will determine which interrupts, if any are to be used.
Card Setup Omega Engineering OMG-COMM8-A Page 6 Interrupt Mode Options The OMG-COMM8-A will allow each port to have an independent interrupt level or share an interrupt with another port on the adapter. The OMG-COMM8-A will even share interrupts with a compatible port that is located on another adapter.
Card Setup Omega Engineering OMG-COMM8-A Page 7 Set jumpers to “ S ” for shared interrupt mode on all blocks sharing an IRQ except one. Set that port block for “ M ”. This provides the pull-down resistor circuit that makes sharing of IRQ possible.
Installation Omega Engineering OMG-COMM8-A Page 8 Installation The OMG-COMM8-A can be installed in any of the full size PC expansion slots, but to access the “AT” or (E )ISA IRQs (10, 11, 12, 15) it must be installed in one of the 16 bit slots.
Technical Descri ption Omega Engineering OMG-COMM8-A Page 9 Technical Description The Sealevel OMG-COMM8-A provides 8 additional serial ports for terminals, modems, printers, etc. The OMG-COMM8-A utilizes the 16550 UART chip. This chip features programmable baud rate, data format, interrupt control and a 16 byte FIFO.

Appendix A - Troubleshooting Omega Engineering OMG-COMM8-A Page 12 Appendix A - Troubleshooting A Serial Utility Diskette is supplied with the Omega Engineering adapter and will be used in the troubleshooting procedures.
Appendix A - Troubleshooting Omega Engineering OMG-COMM8-A Page 13 6. The following are known I/O conflicts: • The 278 and 378 settings may conflict with your printer I/O adapter.
Appendix B - How To Get Assistance Omega Engineering OMG-COMM8-A Page 14 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.
Appendix C - Electrical Interface Omega Engineering OMG-COMM8-A Page 15 Appendix C - Electrical Interface RS -2 32 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-C/D/E or EIA/TIA -232-C/D/E.
Appendix D - Asynchronous Communications Omega Engineering OMG-COMM8-A Page 16 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.
Appendix E – 3421 Addendum Omega Engineering OMG-COMM8-A Page 17 Appendix E - 3421 Addendum The OMG-COMM8-A can be equipped with a higher speed oscillator and the Startech 16C654 UART. This UART has a significantly larger FIFO (64 bytes as opposed to the 16 of the 16C554).
