Boy, your AB rep must be green, we have been using this type of cable for years, check out the following link. http://www.ab.com/sensors/products/photoel...fiberoptic.html

Here is a link to a company who has the converter you need. http://www.fieldserver.com/

The IF4 problem I described is when the base i/o cards have reached the maximum number for the base powersupply .( you can have up to 16 cards depending on the load ) Normally after 8 cards you use an expansion rack made up of an expansion cable, P2 powersupply and an endcap. This rack can have up to 8 cards on either side of the power supply.
