Layout plan for Hjulmarknaden. "X" marks locations for SLAMRA DCC outlets. We run LocoNet over twisted pair cable connected with 6-pin DIN contacts. Sorry RJ12, we just don't think you'd survive our operations. That small locking thingie breaks and you can't get proper protection for it as you can for RJ45. In addition there is no female connector for cable attachment. All these comments will hopefully, eventually appear in a special DCC section.
