Locate an available PCI slot and remove the blank metal slot cover. Gently insert the ULTRA COMM+I.PCI into the slot. Make sure that the adapter is seated properly. Replace the screw. Replace the cover. Connect the power cord. Installation is complete. Sealevel Systems ULTRA COMM+I.PCI Page 7... -
Page 11: Technical Description
Technical Description Technical Description The Sealevel Systems ULTRA COMM+I.PCI provides a PCI interface adapter with an isolated asynchronous serial port providing a versatile interface, field selectable as RS-232 for modems, printers and plotters, as well as RS-422/485 for industrial automation and control applications. Isolation is important in installations where the equipment being connected to the PC is either far from the PC, or on a different power transformer circuit. -

No two adapters can occupy the same I/O address. 3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQs, many other adapters (i.e. SCSI adapters & on-board serial ports) do not. The IRQ is typically selected via an on-board header block. -

RS-422 also defines driver and receiver electrical characteristics that will allow 1 driver and up to 32 receivers on the line at once. RS-422 signal levels range from 0 to +5 volts. RS-422 does not define a physical connector. Sealevel Systems ULTRA COMM+I.PCI Page 13... - Page 17 (Tx+ to Rx+ and Tx- to Rx-). Four wire mode allows full duplex data transfers. RS-485 does not define a connector pin-out or a set of modem control signals. RS-485 does not define a physical connector. Sealevel Systems ULTRA COMM+I.PCI Page 14...
