Chapter 1: Introduction Features • • • • • Individually-Isolated AC/DC Inputs for up to Three 16-Bit Groups, 48 total. Reverse Polarity protection AC Filtering Optical Isolation, Channel-to-Channel and Channel-to-Host PC. Change-of-State detection (certain models). Description This series of cards provide as many as 48 optically-isolated inputs for AC/DC signals with Change-ofState (COS) Detection capability. Each input is reverse polarity protected and rectified by photo-coupler diodes.

Chapter 2: Installation A printed Quick-Start Guide (QSG) is packed with the card for your convenience. If you’ve already performed the steps from the QSG, you may find this chapter to be redundant and may skip forward to begin developing your application. The software provided with this card is on CD and must be installed onto your hard disk prior to use. To do this, perform the following steps as appropriate for your operating system.
Hardware Installation 1. 2. 3. 4. 5. 6. 7. 8. 9. Do not install card into the computer until the software has been fully installed. Turn OFF computer power AND unplug AC power from the system. Remove the computer cover. Carefully install the card in an available 5V or 3.3V PCI expansion slot (you may need to remove a backplate first). Inspect for proper fit of the card and tighten screws. Make sure that the card mounting bracket is properly screwed into place and that there is a positive chassis ground.
Chapter 3: Option Selection Each channel has a jumper configurable filter option. NO FILTER FILTER 3.90" FLT47 FLT31 FLT32 FLT16 FLT 0 FLT15 6.90" Figure 3-1: Option Selection Map Filter Response Switch Jumpers are used to select input filtering on a channel-by-channel basis (see Figure 3-1). When jumper FLT0 is installed, filtering is introduced for input bit 0, FLT1 for bit 1, and so on. The tables below describe filtering for Port 0.
Chapter 4: Address Selection This card uses I/O addresses offset from the base address assigned by the PCI bus. The address spaces are defined in the Programming section of this manual. PCI architecture is Plug-and-Play. This means that the BIOS or Operating System determines the resources assigned to PCI cards rather than the user selecting these resources with switches or jumpers. As a result, you cannot set or change the card’s base address or IRQ level.
Chapter 5: Programming The base address is assigned by the computer system during installation and will fall on an eight byte boundary.

Chapter 6: Connector Pin Assignments Isolated inputs are connected to the card via a 50-pin HEADER type connector. There are three connectors named PORT0, PORT1, and PORT2. The table below describes PORT0. PORT1 and PORT2 are identical pinouts. Pin 50 is located toward the Jumpers, while Pin 1 is located near connection to Motherboard.
