Digital command control, both Motorola and DCC protocols.
I surprised myself in 2004 by changing to digital command control to operate my layout. On eBay I was able to buy an MRC commander 2000 for a nice little price. However, compared to other dcc systems the capabilities with the commander 2000 are limited.
This article is about Motorola switch and signal decoders.
I am using two types of decoders, a low current switch decoder and a high current switch decoder. I also use two types of signal decoders, which can only be used with the MRDirect system.
