Introduction OMG - ULTRA - SIO Page 1 Introduction Overview The OMG - ULTRA - SIO provides the PC with two additional ground isolated RS - 422/485 (P/N 3189) or two non - isolated RS - 422/485 (P/N 3089) serial ports for terminals, modems, printers, etc.
Card Setup OMG - ULTRA - SIO Page 2 Card Setup The OMG - ULTRA - SIO contains several jumper straps that must be set for proper operation. Address Selection Each port on the OMG - ULTRA - SIO occupies eight consecutive I/O locations. A DIP - switch is used to set the base addres s for these locations.
Card Setup OMG - ULTRA - SIO Page 3 IRQ Selection Headers E11 and E12 select the interrupt request for each seria l port. If COM1: is selected, the corresponding jumper must be on the IRQ4 setting. If COM2: is selected, the corresponding jumper must be on IRQ3.
Card Setup OMG - ULTRA - SIO Page 4 Interrupt Modes Header E5 and E6 se lects the interrupt mode for each port. Each port must be set in the correct mode to insure proper operation.
Card Setup OMG - ULTRA - SIO Page 5 Set the jumper to ‘ S ’ if you are using more than one OMG - ULTRA - SIO in a bus or to completely r emove the pull - down resistor for hardware compatibility. Setting the adapter in this configuration when it is not accompanied by a pull - down resistor will prevent the ports from triggering an interrupt .
Card Setup OMG - ULTRA - SIO Page 6 Headers E8 (Port 1) and E10 (Port 2) are used to control the RS - 485 mode functions for the driver circuit. The two selections are ‘RTS’ enable or ‘Auto’ enable. The ‘Auto’ enable feature automatica lly enables/disables the RS - 485 interface.

Card Setup OMG - ULTRA - SIO Page 8 Line Termination Typically, each end of the RS - 485 bus must have line terminating resistor s (RS - 422 terminates at the receive end only). A 120 ohm resistor is across each RS - 530/422/485 input in addition to a 1K ohm pull - up/pull - down combination that bias the receiver inputs.
Installation OMG - ULTRA - SIO Page 9 Installation System Installation The OMG - ULTRA - SIO can be installed in any of the PC expansion slots. The OMG - ULTRA - SIO contains several jumper straps for each port which must be set for proper operation. 1.

Appendix B - How To Get Assistance OMG - ULTRA - SIO Page 14 Appendix B - How To Get Assistance Please refer to Troubleshoot ing Guide prior to calling Technical Support. 1. Begin by reading through the Trouble Shooting Guide in Appendix A. If assistance is still needed please see below.
Appendix C – Electrical Interface OMG - ULTRA - SIO Page 15 Appendix C - Electrical Interface RS - 422 The RS - 422 specific ation defines the electrical characteristics of balanced voltage digital interface circuits. RS - 422 is a differential interface that defines voltage levels and driver/receiver electrical specifications.
Appendix D - Ground Loop Phenomenon OMG - ULTRA - SIO Page 16 Appendix D - Ground Loop Phenomenon What is Ground Loop? Ground loop Phenomenon occurs when two (or more) pieces of equipment are connected together with a common ground and a different ground poten tial exists at each location.
Appendix E - Asynchronous Communications OMG - ULTRA - SIO Page 17 Appendix E - 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.
