Review: Great troubleshooter - HO trains are my passion. Many assemblies (locomotives and related electronic items) require either setup or fine-tuning to work. This interface gives me a chance to quickly and easily meet the requirements of my layout. A very handy 'tool' to have around IMHO.
Review: Works great - Decent quality. Kind of pricey, but if you need the ease of connection the screw terminals offer, it's worth it. It was intended for an RS232 breadboard, so it should serve well for many years.

Decent quality. Kind of pricey, but if you need the ease of connection the screw terminals offer, it's worth it. It was intended for an RS232 breadboard, so it should serve well for many years.
