The Powerhouse Pro is the most user friendly DCC system on the market. Other DCC systems require memorization of arcane simultaneous button sequences and computer hexadecimal numbers to accomplish the simplest tasks. Our ProCabTM walks you through every operation with clearly labeled buttons and well thought out menu prompts in plain English on the back lit LCD display of the Cab. The most often performed operations usually are just a single key press. It includes the user friendly ProCabTM, Command Station with integral Five Amp power unit. The Quick Start Guide in our system reference manual will have you up and running in less than 20 minutes. Should you ever need it, the entire system can be easily upgraded by simply swapping out a single program memory chip (no returns to the factory!). An RS-232 port is supplied for those wishing to add computer control to their layout. Suggested power supply is NCE P515 For specs visit the product's webpage by clicking on the link below.
