Summary: The LC100 Command Station Converter connects other manufacturer's Digital Command Control systems to a Lenz DCC system. The LC100 Command Station Converter by Lenz is a digital protocol converter which connects other manufacturer's Digital Command Control systems to a Lenz DCC system with the Lenz XpressNet system.

The LC100 is no longer made.

Devices Which Can be Used with the LC100

Devices that transmit the standard NMRA DCC packet to the track can be connected to the LC100, including the following systems:

  1. ROCO Digital is Cool
  2. LGB Digital
  3. Components of Marklin Digital for DC systems and Marklin Digital I.
  4. Arnold Digital and Arnold Commander 6

What Does the LC100 Do?

The LC100 "listens" to the booster's track output, all commands that would be sent over the track to locomotives or turnouts are read by the LC100. The LC100 looks for changes in the data received, and sends those to the command station using XpressNet . The communication is strictly one way, no information can be sent from the LZ100 to the 'foreign' digital system. The foreign system is not connected to the track, the Lenz command station and booster replace them.


The advantage of this set up is that you can use any input device as a Cab on an XpressNET based system provided it uses the NMRA DCC track signal. For example, using a dispatcher's panel built from switchboards to set your turnouts, or setting complex routes through the interface.


Foreign DCC System

The track output terminals on the booster of the foreign DCC system are connected to the terminals labelled central station on the LC100.


The terminals connecting the LC100 to XpressNET are located on the right hand side of the unit.

Connect the four terminals (L, M, A, B) to the identical terminals on the Command Station's LZ100 or LA152, or using an XpressNET port on your system. The connection does not need to be directly to the Command Station, it can be done at any point on the XpressNET, such as at a LA150/151 connector plate. When wiring an XpressNET extension, the L / M and A / B wires have to be laid out as twisted pairs.

Connecting the LC100 to other NMRA DCC Systems

The LC100 can connect any NMRA DCC system to the DIGITAL plus XpressNET.

The LC100 can only translate speed, direction, function commands, and turnout commands. It can not translate programming commands or advanced commands such as consist setup, or 128 speed step commands.

NMRA DCC Commands Supported

The following NMRA DCC commands are currently supported by the LC100:

Locomotive Addresses 1-99
14 Speed Step Speed andDirection Commands 14 speed step on of "foreign"system will be converted to the current locomotive speed step setting on the XpressNet system.
Function Group 1 1-4
Accessory Addresses 1-64
Emergency Stop If the "foreign" system ceases transmitting packets the LC100 considers this an emergency stop indication.

XpressNET Address

The LC100 address is fixed at 30. Therefore, no other device connected to XpressNET can use the this address. Changing the address on an LH100 or LH200 Handheld, Tower Cab (LW100) or the Computer Interface (LI100). Employing 2 LC100 units, require one to be programmed to different address.
