I would not want to trust that variable. Sooner or later that will be a service call. I would bit the bullet and go to RS232, and then never sell that PJ again until they change the IR control table. I refuse to sell components that refuse to include discete IR. Too many others that pay attention to that. I though Sim2 was one of them. Evidently not!
Chasing Ernie's post count, one useless post at a time.
