Overview

As the name implies, the Booster Adapter is a product which can be used to adapt different manufacturers' boosters (and command stations) together. This product is intended to offer you, the user, a quick and easy way to "plug and play" with your command station and boosters. Whether you are upgrading your booster network, command station, or both, the Booster Adapter can help make your update quick and painless!

The Booster Adapter has several on-board plug and terminal connections for:

  1. LCC CAN-Bus
  2. NCE "Control Bus"
  3. Digitrax "LocoNet-B"
  4. Lenz

Some use cases include:

  1. Connecting a CS-105 to NCE Booster(s)
  2. Connecting a CS-105 to Digitrax Booster(s)
  3. Connecting a CS-105 to Lenz Booster(s)
  4. Connecting a Digitrax command station to NCE Booster(s) (and vice versa)
  5. Connecting a NCE command station to TCS Booster(s)
  6. And many more combinations!

The BA-100 can also provide power for other LCC devices distributed around your layout using the on-board barrel jack and an external 15V power supply (not included).

Included In Package

  • BA-100 Booster Adapter board x1
  • Option Jumpers x4

Configuration Jumpers

Refer to the table below for information on the configuration jumpers available on the Booster Adapter:

Jumper Position Description
DCC Polarity This pair of jumpers is used to change the phase of the DCC signal between the LCC Jacks and all of the other jacks on the board.

This is useful if all of your non-TCS booster districts are wired the same as one-another, but are out of phase with a CS-105. Rather than having to flip the polarity of the track wires for each booster district, this pair of jumpers can be switched to the || “Reverse” position to invert the phase of the DCC signal passing through the panel.

The default position is = “Normal” which will not invert the phase.

LCC Power This pair of jumpers is used to route power for the LCC jacks.

The default position || “Pass” will allow LCC power to pass throgut the BA-100 (pins 7 & 8 of the LCC-CAN standard)

By moving both jumpers to the = “Output” option will allow you to power the LCC jacks using an external 15VDC power supply

Remove these jumpers to prevent LCC power from passing betwen the LCC jacks through the panel.


Power Station Interface on TCS Command Stations and Boosters

TCS products use the OpenLCB/LCC NMRA S-9.7.1.1 CAN Physical Layer, which consists of an RJ-45 connector routing the CAN signals, power, and the two ALT signals on pins 4 & 5. This diagram below shows the pin-out for the RJ-45 connector as used in S-9.7.1.1 and on the TCS CS-105 and B-106 products. TCS utilizes the ALT_L/ALT_H signals on pins 4 & 5 (labeled DCC B & DCC A) for the Full Scale Power Station Interface. These signals are used when connecting to other manufacturers' command stations and boosters.


LCC Pinout.png


Pin 4 "DCC B" is the "Low" rail, which swings negative during the DCC signal procession. When wiring a layout, this pin will correspond to the "Left" rail (typically BLACK). On the CS-105 the DCC B pin corresponds to and follows the Mainline output pin labeled "B".

Pin 5 "DCC A" is the "High" rail, which swings positive during the DCC signal procession. When wiring a layout, this pin will correspond to the "Right" rail (typically RED). On the CS-105 the DCC A pin corresponds to and follows the Mainline output pin labeled "A".

When wiring a TCS Command Station into a TCS booster, all you need to do to pass these signals is to connect a single RJ-45 cable between the LCC ports on each device. For examples of ways that you can interface a TCS Command Station with other manufacturers' boosters, or a TCS booster with another manufacturer's command station, see the examples listed below.

Digitrax CS to TCS Booster or TCS CS to Digitrax Booster

Booster Interface (LCC to Digitrax).png
Important Requirement: Most Digitrax boosters are not electrically isolated (sometimes referred to as "opto-isolated"). Unless using an electrically isolated booster, a booster common must be used. The booster common terminal is typically labeled "GR" on Digitrax boosters and command stations and labeled "Common" on TCS boosters and command stations. For more information, see section #Booster Common below.

Lenz CS to TCS Booster or TCS CS to Lenz Booster

Booster Interface (LCC to Lenz).png
Note: All Lenz Boosters are electrically isolated, however a booster common is still recommended. The booster common terminal is typically labeled "⊥" on Lenz boosters and command stations and labeled "Common" on TCS boosters and command stations. Some Lenz command stations and boosters do not have a booster common terminal. For more information, see section #Booster Common below.

NCE CS to TCS Booster or TCS CS to NCE Booster

Booster Interface (LCC to NCE).png
Note: All NCE Boosters are electrically isolated, however, a booster common is still recommended. The booster common is typically found on the metal enclosure screw(s) on NCE boosters and command stations and labeled "Common" on TCS boosters and command stations. For more information, see section #Booster Common below.


Configuration Settings

TCS command station and booster products are integrated with advanced RailCom® features. Most boosters on the market do not support the same advanced RailCom® feature set. As such, it is best to appropriately reconfigure certain settings as described below depending on your setup.

When using a TCS command station with a booster that does not support RailCom® feedback over the Power Station Interface, it is recommended to choose the "Enabled with no RailCom" option for the System Settings -> Advanced Options -> Drive LCC Boosters option.

When using a TCS Booster with a command station that does not support RailCom® it is recommended to choose the "Disabled" option for the Persistent Settings -> Options -> RailCom Cutout option.

Output Voltage Matching

When using two or more boosters together, their track output voltages should be closely matched. A good target is less than 0.8V difference in no-load output voltage between any two boosters. A general purpose AC voltage meter is designed to accurately measure 50Hz/60Hz sinusoidal signals, like what is delivered by the power company. Though it will not provide an accurate absolute output voltage reading on a DCC booster (which produces a square wave signal), for comparative purposes, any general purpose AC voltage meter can be used to measure a booster's output voltage for differences.

  1. Set your multi-meter to AC voltage measurement.
  2. Measure across the two output rails in one booster district, note the reading.
  3. Measure across the two output rails in the other booster district, note the reading. (Repeat as many times as necessary)
  4. Compare the two noted readings. If they are closer than 0.8V from one another, then they are close enough.

Output Phase

Every booster has two outputs, one for each rail. If a locomotive creates a short circuit when passing between two booster districts, this is a likely indicator that the two boosters are out of phase of one another. In this case, swap the two rail outputs on one of the boosters to bring them back into phase with one another.

Booster Common

A booster common provides a controlled low impedance return path between boosters which helps with the transition of a locomotive between two booster districts. A booster common should use heavy gauge wire designed to carry the full current rating of the booster(s), 14AWG or larger is recommended.

Non-Electrically Isolated Boosters

When using boosters that are not electrically isolated, a booster common is required. Most Digitrax boosters are not electrically isolated and require a booster common.

Electrically Isolated Boosters

All TCS boosters provide electrical isolation, as do boosters from Lenz and NCE. Some Digitrax boosters are also electrically isolated and can be identified by the label "Opto equipped". When using boosters that have electrical isolation, a booster common is technically optional, but still highly recommended for the following benefits:

  1. Support for locomotives with "split frame" electrical pickup scheme. This is especially common in older steam locomotives where the locomotive would have pickups on one rail and the tender pickups on the other rail.
  2. Prevent voltage doubling between two boosters that are out of phase with one another.

Some electrically isolated boosters do not offer a booster common. In this case, a common rail can serve a similar purpose. This is achieved by tying together one output phase or rail of each booster. It is important not to mix together booster common and common rail schemes. Only one type of common should be in use on a given installation.
