Introduction The PIO-96.PCI part number 8009 digital I/O interface provides 96 channels of buffered drive digital I/O emulating 8255 mode zero. The PIO-96.PCI can be utilized for a variety of control and automation applications including control and monitoring of TTL devices (e.g. LEDs, small solenoids, small relays) and interfacing to solid-state relay racks (SSRs) for high-power AC or DC loads. The PIO-96.
Before You Get Started What’s Included The PIO-96.PCI is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. PIO-96.PCI Adapter Sealevel SeaI/O Software CD Optional Items Depending upon your application, you are likely to find one or more of the following items useful for interfacing the PIO-96.PCI to real-world signals. All items can be purchased from our website (http://www.sealevel.com) or by calling (864) 843-4343.
For high-current, high-voltage applications: IDC 50 to IDC 50 Pin Ribbon Cable (Part Number CA167) − 40” cable connects the PIO-96.PCI to solid-state relay racks equipped with 50-pin header interface. IDC 50 to IDC 50 Pin Ribbon Cable (Part Number CA135) − 40” cable connects the PIO-96.PCI to solid-state relay racks equipped with 50-pin edge connector. Solid-State Relay Racks: • Quad six position relay rack (Part Number PB24HQ) − Relay rack can accept up to six QSSRs for a total of 24 channels.
Software Installation Windows 98/ME/2000/XP Installation 1. Start Windows. 2. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD 4. Select ‘Install Software’. 5.

Linux Installation Note: You MUST have "root" privileges to install the software and drivers. 1. Login as "root". 2. Mount the CDROM by typing: mount -t iso4860 /dev/hdc /cdrom Note: Your cdrom may not be /dev/hdc it could be /dev/hda, /dev/hdb, /dev/hdd, or if you have a SCSI drive /dev/sda, /dev/sdb, /dev/sdc, etc. You may mount the CDROM to any location, the /cdrom is just a common example. 3. Next change to the directory where you mounted the CDROM: Ex.
Physical Installation The adapter can be installed in any 5V PCI expansion slot. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available 5V PCI slot and remove the blank metal slot cover. 4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly. 5.
Digital I/O Interface The PIO-96.PCI’s 96 digital I/O channels are accessed via four industry-standard 50-pin header connectors. Each header provides 24 bits of digital I/O divided into three eight-bit ports. Each port may be individually configured via software command as input or output. 50-pin Header Connectors You will need to install the bracket assembly and cables to the PIO-96.PCI prior to installing it in the PC. The PIO-96.
Programming the PIO-96.PCI Sealevel’s SeaI/O software is provided to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. Included on the SeaI/O CD are driver functions for use in accessing the I/O as well as helpful samples and utilities. Programming for Windows The SeaI/O API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL).
Presetting an Output Port Each port has an output register associated with it. This register may be written and retains its value whether the port is configured as an input or an output. To preset the value of an output port the program should write to the port when it is configured as an input then configure it as an output. Writing the Outputs The outputs are active true. Writing a one (1) corresponds to 5V while writing a zero (0) corresponds to 0V, at the output.
I/O Control Word Each port may be configured as either Input or Output. This is accomplished by writing the correct Control Word (CW) to the proper register.
Electrical Characteristics The PIO-96.PCI uses 74LS245 octal bi-directional transceivers to provide TTL input/output capabilities. Each bit is pulled to +5V through a 10K ohm pull-up resistor to insure each bit is at a known state when not driven. Specifications Inputs Logic High: Logic Low: Min 2VDC Max 0.8VDC Outputs Logic High: Logic Low: Min 2VDC @ 15 mA Max 0.
