Introduction and Installation Introduction Overview The OMG-PCI-DIO48 provides two 8255 mode 0 compatible ports providing four eight-bit ports and four four-bit ports. Each can be individually configured as inputs or outputs. When configured as outputs each bit of the four bit ports may be set or reset individually. What’s Included The OMG-PCI-DIO48 is shipped with the following items. If any of these items is missing or damaged, contact the supplier.
Introduction and Installation System Installation The OMG-PCI-DIO48 can be installed in any of the PCI expansion slots. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available PCI slot and remove the blank metal slot cover. 4. Remove the clamping portion of the bracket from the card. 5. Gently insert the OMG-PCI-DIO48 into the slot. Make sure that the adapter is seated properly. 6.
Technical Description Technical Description The OMG-PCI-DIO48 provides 48 channels of digital I/O configurable as inputs or outputs, which can be utilized for PC based control and automation including sensors, switches, satellite antenna control systems, video and audio studio automation, security control systems, and other industrial automation systems. Software The OMG-PCI-DIO48 ships with the SeaI/O suite of Windows 98/NT/ME/2000 drivers.
Technical Description 3rd Party Software Support Third party software support for many HMI/MMI and other process control software is included on the product installation CD. For the most up to date information on third party software support, please visit http://www.omega.com.
Technical Description Electrical Characteristics The table below provides the electrical characteristics of each Input/Output. Each port is buffered with a 74LS245 octal bi-directional transceiver. Each input is capable of sinking up to 24 mA, while each output can source up to 15 mA. Recommended Operating Conditions Min Input 0V Source Sink Max 5.25 V 15 mA 24 mA Electrical Characteristics High Level Input Voltage Min 2 V Low Level Input Voltage Max 0.
Technical Description Pull Ups Ten pin bussed resistor packs are installed to provide pull-ups to the input ports. These are installed on all ports. The pull-up resistor packs are rated at 10K ohms. Figure 2 below provides the bussed resistor and corresponding port. The resistors insure that no line is floating which is not connected. This provides consistent biasing on all un-terminated lines.

Technical Description Application Programmers Interface (API) Most modern operating systems do not allow direct hardware access. The SeaIO driver and API have been included to provide control over the hardware in Windows and Linux environments. The purpose of this section of the manual is to help the customer with the mapping of the API to the actual inputs for the 8005 specifically. Complete documentation of the API can be found in its accompanying help file.
Technical Description Port C relative addressing (when port C is split) The input and output nibbles will each be treated as individual four bit ports. Port Configuration: Each eight-bit port can be configured as inputs or outputs. The API provides a set adapter state call to access the control words. For this device, two control word is used. Refer to the following table. Note: : The control panel also allows you to configure the device.

Technical Description The following tables are provided for the user in the event that he/she wishes to record their particular relative addressing setup, provided its constant. Print this page and fill in the tables starting in the top left corner of each and work from top to bottom, left to right. Start with zero on the first input and increment by one on each additional input. Next move to outputs and again start with zero and increment by one on each additional output.

The address of each eight-bit port is calculated as shown in the table on the following page, the cards base address plus an offset. Reading the Inputs: The inputs are active high. If an input is driven high (2V to 5.
Technical Description Interrupts Interrupts can be set up as shown in the tables on the next page.
Technical Description Port C Port C is written and read to as a single eight bit port, but it has the ability to be configured as two four bit ports. If both lower and upper nibbles are configure the same then no special considerations need to be made. But if they are configured differently, one nibble as input, and one as output then the user will have to keep this in mind.
