I am new to the community. I make one-off arcade machines which use PLCs for control with Brightsign players for sound and video. I had a brightscript (autorun.brs) written in 2011 to convert 6 outputs from the PLCs to a binary form to trigger 64 tracks on the player. It works fine on all my old LS 422 players running firmware version6.2.45. I just bought an LS 424 with a GPIO adaptor (running firmware 8.0.22) and it no longer runs. I haven't been able to find any reference to similar problems on the web but I'm hoping it will be familiar to someone in the community.
brightscript written in 2012 won't run on LS424
