DIGITAL plus LZ100 Command Station
The core of the DIGITAL plus professional grade systems is the Command Station LZ100. It coordinates the input devices (Hand Held Controller LH100, LH200, LW100,etc.) and is also responsible for generating the NMRA DCC signal and general data processing. Information is exchanged between Command Station and input devices via a 4-wire cable, XpressNET. The Command Station generates the control signals which are fed to one or more Power Stations (boosters) , which combines them with the necessary power and sends them to locomotive and accessory decoders.
The Command Station has no boosted output to connect to tracks. Accordingly it only needs a small transformer (15VA), which could be one you already have from a starter set. If you use a more powerful transformer, you can connect the Command Station and the Power Station to the same transformer. Please note however that a minimum of 13 volts AC or 16 volts DC is necessary to power the LZ100. If you are using a full complement of 30 XpressNET devices, the input power should be raised to a minimum of 30 VA.
To get started with DIGITAL plus, you will also need: a hand held controller ( LH100, or LH90 ); a power station ( LV101 ) or other power station from a different manufacturer); a locomotive equipped with a DIGITAL plus locomotive decoder or with another NMRA DCC compatible locomotive decoder; and a transformer providing 13-16 volt AC and 15VA output.
Version 3 of the LZ100 has been tested by the NMRA for conformance to its DCC Standards and Recommended Practices and has earned an NMRA conformance warrant.
