I contacted Standard Horizon and their tech support got right back to me,
but the news was not good..

The DSC option board is no longer available.

However, if I can find one in old stock, from a dealer, I can install it
myself.. Simple plug in job.

I'll do some Google searches for this CDS2300 board and cross my fingers..

There is also a good marine elex repair shop (father/son) in seattle that
may be able to get it for me.
