The 232 to 485 converters appear to be $45/ea.; I'm assuming I would need two, one for each end?
As a possible alternative, I came across a 232 to Cat 5 converter for $50. (I would post the URL, but the forum won't let me embed links until I have reached 15 posts. The converter is at Monoprice.com, product ID 3598.) This converter includes both the local and remote units. Would this be a better solution, if I can just run a Cat 5 cable in between the projector and sound booth?
