Introduction The DIO-104.OPTO is a PC/104 form factor adapter that provides 16 optically isolated inputs (rated for 3-13V) to allow monitoring of off board switch closures, relays or for any other general purpose monitoring needs. The DIO-104.OPTO is designed to be used with a variety of Operating Systems including Windows 98/NT/ME/2000/XP and DOS. The SeaI/O API (Application Programmer Interface) included on CD with the DIO-104.
Before You Get Started What’s Included The DIO-104.OPTO is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. DIO-104.OPTO 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 DIO-104.OPTO to real-world signals. All items can be purchased from our website (http://www.sealevel.com) or by calling (864) 843-4343.
Card Setup Address Selection The DIO-104.OPTO occupies 4 consecutive I/O locations. The DIP-switch (S1) is used to set the base address for these locations. Be careful when selecting the base address as some selections conflict with existing PC ports. The following table shows several examples that usually do not cause a conflict. Even though four I/O addresses are decoded, only the first two are actually used, the other two ports are to maintain compatibility with existing Sealevel Systems adapters.
Software Installation Windows 98/ME/NT/2000/XP Installation Do not install the Adapter in the machine until the software has been fully installed. 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. Select the Part Number for your adapter from the listing. 6.
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 iso9660 /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 Extreme care should be taken when installing the DIO-104.OPTO to avoid causing damage to the connectors. After the adapter is installed, connect your I/O cable to P2. Please note these headers are keyed so that pin 1 of the cable matches pin 1 of the connector. Refer to Card Setup for information on setting the address before inserting the DIO-104.OPTO onto the stack. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off power.
Programming the DIO-104.OPTO 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).
Input Ports Ports A and B are 8 bit input ports connected to optically isolated input sensors. Each sensor can be used to interface a voltage input and then sense whether the voltage is on or off. Each sensor is isolated with respect to a common ground from every other sensor and also isolated with respect to the host PC ground.
