the pen tray has a gold box mounted underneath)?
You can certainly use this version of SMART Board software with older interactive whiteboards, including models with: PT3 pen tray some PT5 pen trays (those equipped with the bottom-mounted gold box) PT4 pen tray, which are in older Rear Projection SMART Board interactive whiteboards (RPSB 585s and RPSB 420s) The only difference you’ll notice is that the Ready Light in your pen tray will flash approximately every four seconds during use. Don’t be alarmed by this flashing. It represents normal behavior and shouldn’t be mistaken for a malfunctioning pen tray. However, you must continue using your original serial cable connection, as these pen trays do not support the SMART USB adapter.
