The fORP has been in production since 1996 when the Legacy fORP electronic interface, based on a fragile fiber optic bundle, used a hand-built optical d-connector. The button boxes were made from plastics disks and typewriter keys. Generating different outputs for button presses required changing the PICT Chips.
The FIU-004/005 interface and handhelds began production in 2003 with the circular optical connector. A compact 8-position program switch allowed for several program options on all three output connectors (Serial, USB, Parallel). Handhelds could have up to 8 buttons and the joystick and trackball were developed for variable optical output.
In 2009 we introduced the 900 series with three levels of interface offered a range capabilities. The FIU-904 was inexpensive and compact. The the FIU-932 was very flexible and worked with all our devices.
In 2020 we began shipping the latest interface, BIRCH-OIU. The bright 7" touch screen display displays responses as they happen and simplifies mode selection. it is a drop-in replacement for the 932 interface and compatible with existing handhelds and bundles. While we no longer support the electronics or optical components of the the legacy fORP, this sections lists peripherals that can be purchased.
