[Link: speakercraft.com]: RSA-1.0
Speakercraft have firmware for the RSA 1.0 that can make it accept 240 different IR commands which are each associated with an RS232 macro. The macro can incorporate multiple strings with delays in-between if necessary. You can right click on a macro in EZTools (the MZC/RSA programming software from Speakercraft) and generate pronto hex to import into whatever control system's triggering the RSA.
