Below is a discussion of the command stations offered by NCE from a production history point of view.

NCE SB3 Command Station History
The short lived SB3 had a 3 Amp booster and was built into a plastic box. Unfortunately it was not very reliable. With poor heat and short circuit protection, the unit often failed. In an attempt to address the heat issue, NCE added holes to the case to increase ventilation. The short circuit issue required the user to add external Automotive light bulbs in series with the output to limit the sustained current. Acknowledging the system faults, NCE later offered customers a free upgrade to a SB3a.
The SB3a came in a new more compact plastic case with an improved 5A booster. Software wise, it is the same as the SB3. However the booster designed is based on the PB105 booster design. The SB3a also offers the option of defeating the command station and becoming a 5A Booster. The conversion is done with a flip of a switch on the bottom of the box and a software setting change.
NCE High End Command Station History (Master Series/PowerHousePro/PowerPro)
NCE's top of the line command station has evolved over time. Originally the CS01 command station had 2 CabBus jacks on the front panel. The 2 Cab bus jacks made it very easy to place the command station anywhere in the Cab bus run.
CS01 Command Station
Notice on far left, near the screw terminals for power, are 2 Cab Bus telco Jacks side by side.
This is also true for the Wangrow/SYS1 CSP01 Command Station. NCE designed this for System One.
That all changed when NCE introduced the new CS02/PowerPro Command Station.
CS02 Command Station
Notice there is only ONE Cab Bus telco Jack on the far right next to the Red LED. The left side of the box is empty inside and out.
The CS02 is also used in the PowerPro (PowerHouse) system.
A PowerHouse system is a CS02 above PLUS a booster installed on the left. It therefore has the same single Cab Bus connection.
Other than a name change, this system is the same as the PowerHouse station but eliminated the need for two input power connections. Notice there is no power connection on the right side when compared to the PowerHouse picture above. The power comes from the booster side on the left.
