What is Lionel’s Layout Control System?
LCS doesn’t replace your existing Lionel Legacy Control system. It adds to it! You can control your
layout from Lionel Cab Remote controllers or from smart devices like an Apple iPad and run
locomotives, operate track switches, accessories and lighting. Create automatic events to control
passing locomotives and other layout accessories or switches.
LCS is a modular system, with each product offering unique features. No single LCS product
will do everything and not every layout will require every type of LCS device. But a fully realized LCS
system will likely include the following:
• A Lionel Command Base (Legacy or Base-1L) for locomotive control
• LCS WiFi so you can control your layout from smart devices like an iPad®
• LCS ASC2, to operate switches, lighting and accessories
• LCS BPC2 for block power control
• LCS SensorTrack (one or more) which adds a new level of interactivity with compatible Lionel
Legacy and Vision locomotives
• LCS SER2 for computer control and use of existing Lionel serial devices like the TPC-300 and
TPC-400
How it works!
As you know, your Lionel Cab Remote sends commands to your Command Base. In turn, the base controls your locomotives via a one-way communication link. LCS works in
parallel with your existing command base, adding a wired network of control modules. Spread
across your layout, these LCS modules operate switches, lighting, accessories and track power
blocks. LCS is bidirectional, meaning modules can send and receive commands.
And here’s where it all comes together: Since LCS can also send commands back through
the command base, LCS devices can operate your locomotives as well as your layout! For
example, a module like SensorTrack™ can make a loco blow a grade-crossing signal as it
passes. And the LCS WiFi module connects devices like an Apple iPad®to your layout so you
and your friends can easily operate switches, locos and more.

LCS ASC2 Module
The ASC2 module is designed to be connected to track switches and accessories on your model railroad layout. Then you can control these connected switches and accessories
from a Lionel hand-held remote or a smart device such as an Apple iPad® and an LCS
WiFi module.
• When configured in switch mode, an ASC2 operates up to four remotely operated switches
from Lionel and other manufacturers.
• The ASC2 has eight Normally Open relays, with four banks of two complementary outputs.
One pair of relays will activate the “THRU” position with one set of contacts, and the other
set of contacts will activate the “OUT” position.
• Each relay is rated at 20 amps.
• When configured in accessory mode, up to eight lights, uncoupling tracks or basic on/off
accessories can be controlled.
• Accessory mode is configured as 8 normally open relays, split into two banks of four. Each
of these two banks has a common terminal feed.

Installing Your First LCS Device
The following section describes installation of a new LCS system. If you already have installed your first LCS component, please skip ahead to the next section titled “Installing additional
LCS devices.”
When installing a new LCS system, the process you will follow depends on which (if any) Lionel
Command Base is to be connected to your LCS system. Following sections describe starting a new LCS
installation with a Legacy Base, a Base-1L or without any command base.
The LCS DB-9 Cable with Power Supply
Every LCS system requires exactly one 6-81499 LCS DB-9 Cable with Power Supply. This special cable has three connectors: (A) a DB-9, with a “pig-tail” cable-mount power supply connector
(C) and also a 10-foot cable with an “LCS PDI” connector at its end (B). See below:
The cable receives power from the included DC wall-pack (12VDC at 1A). Power for each LCS
device is supplied through the single LCS data cable. The LCS DB-9 Cable with Power Supply wall-
pack is capable of powering dozens and dozens of LCS devices, depending on type. An additional
power booster/cable extender is available for extremely large LCS installations.
Figure 3. The LCS DB-9 Cable with Power Supply (sold separately)

Installing LCS with Legacy AND TrainMaster Command Bases
The following instructions apply ONLY if you are using one or more original CAB-1 remotes with a Legacy command base. It is not necessary to follow these instructions to use the CAB-1L remote
with a Legacy command base.
In order to complete this installation, you will need a CAB-1 remote, an original TMCC
Trainmaster command base, a Legacy Command Base with Legacy CAB-2 remote and the Legacy
serial Y cable (included with the Legacy command base).
This is the ONLY supported application for the Legacy Y cable. The “Command base” end
of the Legacy Serial Y cable cannot be directly connected to any accessory other than the
original TMCC TrainMaster command base.
To install a new LCS system on a layout with a Legacy Command Base, an original TMCC
Command Base and a Legacy Serial Y Cable:
1. Turn off power to your layout, Legacy Base and TMCC TrainMaster command base.
2. Connect the DC wall-pack to the female cable-mount connector of the LCS DB-9 Cable.
3. Connect the DB-9 connector of the Legacy Serial Y cable to your Legacy Command Base.

Installing LCS with Legacy AND TrainMaster Command Bases
(continued)
Your system should resemble the figure below.
Once connected and powered-up, the yellow LED on the Legacy Base will blink once every second.
With this setup, you can control Lionel locomotives and Layout Control System products using any
combination of LEGACY Remotes, CAB-1L remotes and original CAB-1 remotes.
If you have additional LCS devices to install, see “Installing additional LCS devices”. If not, skip
ahead to the next section of this manual, “Configuring your LCS Device.”

11
Installing a new LCS system with NO Command Base
The Layout Control System can be used without a Lionel Command base. This would be appropriate for a layout which only uses “conventional” or “transformer-controlled” locomotives
or a different type of locomotive control system such as DCC. An LCS WiFi is required, as are one other
LCS module (such as ASC2 or BPC2).
1. Connect the DC wall-pack to the female cable-mount connector of the LCS DB-9 Cable.
2. Connect the LCS PDI cable end of the LCS DB-9 Cable to either connector on your LCS WiFi.
3. Set the Base/No Base switch to “NO BASE.”
4. Leave the DB-9 connector of the LCS DB-9 Cable unconnected.
5. Plug in the LCS wall-pack power supply.
With this setup, you can control other Layout Control System products using compatible software
on smart devices connected via WiFi or from a computer using a wired serial connection via an
LCS SER2. Since this configuration does not include a command base, you will not be able to use
Lionel Cab Remotes, command-controlled locomotives or wireless command controlled switches or
accessories in conjunction with this LCS system.
If you have additional LCS devices to install, see “Installing additional LCS devices”. If not, skip
ahead to the next section of this manual, “Configuring your LCS Device.”

Installing additional LCS devices
This section describes adding a new device to an existing Layout Control System installation. If you are installing a brand new LCS system, please refer to the previous section of this document,
“Installing Your First LCS Device.”
Adding additional LCS devices to an existing Layout Control System requires an additional
cable for each new device. These “LCS PDI Cables” come in a variety of pre-made lengths. They are
not included with LCS devices, and must be purchased separately. LCS PDI Cables are available in
a variety of lengths:
6-81500 - LCS PDI 1ft Cable
6-81501 - LCS PDI 3ft Cable
6-81502 - LCS PDI 10ft Cable
6-81503 - LCS PDI 20ft Cable
Each new device is connected via LCS PDI cables in a “daisy-chain” fashion (one to the next, and
so on). The order of devices in the “chain” is up to you. The only exception is that an LCS WiFi must
be the first device in the chain if no Lionel Command Base is present.
To connect each additional LCS device:
1. Find the “last” LCS device in the chain. One if its two LCS PDI connectors will be in use, the other
will be empty.
2. Using your chosen length LCS PDI Cable, connect one cable end to the unused LCS PDI connector
of the last LCS device in the chain.
3. Connect the second cable end to either of the LCS PDI connectors on your new LCS device (see
figure below). Your new LCS device is now the last one in the chain.

Connect Accessory Transformer to Relay Power Terminals
Your ASC2 requires an external power source to operate its 8 internal relays. This must be supplied from a separate accessory transformer and is required for both Accessory or
Switch configuration of your ASC2.
Connect an accessory transformer with an 12-14 VCA output to the ASC2’s front screw
terminal connections marked “A” and “U” as shown in Figure 9 below. If your installation
includes more than one ASC2, they can share the same accessory transformer as long it the
combined current draw of the relays does not exceed the capacity of the accessory transformer
(See Specifications, Electrical at the end of this document).
Figure 9. Connecting two ASC2 modules with LCS PDI cables and parallel external relay power.
The ASC2 requires separate external power to operate its internal relays. Multiple ASC2
and/or BPC2 modules can be wired in a daisy-chain fashion as shown above.
When connected to switches, lighting or accessories, the ASC2 will switch on and off the
power to these connected devices. However, the power to these external devices will simply be
passing through the ASC2 relays. The ASC2 does NOT supply the operating power required by
connected switches, lighting or accessories.
To connect the Relay Power Terminals on your ASC2:
1. Attach one wire to the Common/Ground/U terminal of your transformer and connect it to
the POWER U terminal on the ASC2 unit. Do not connect this terminal to the outside rail.
2. Attach another wire to the Power/A terminal of your transformer and connect it to the
POWER A terminal on the ASC2 unit.
3. If your layout includes additional ASC2 or BPC2 devices, you can use the spare A and U
terminals on the first unit to jumper power to your next ASC2 device as shown in Figure 9.

Understanding ASC2 Software Configuration
Your ASC2 software configuration is a single operation that sets three distinct features:
1. Switch mode vs. Accessory Mode
2. The base address/TMCC ID used to control connected accessories/switches
3. Sub-mode setting. For accessories, the sub-mode chooses between operating an assortment
of accessories and/or lights vs. using an ASC2 exclusively to control up to 8 independent
uncoupling tracks. For switches, the sub-mode chooses between quick-operating switches
(like FasTrack) or slow-acting switches.

Switch vs. Accessory Mode
You cannot mix switch and accessory modes in a single ASC2.
In Accessory mode your ASC2 will respond to commands sent to “accessory IDs” from your
remote. Up to 8 accessories are supported on a single ASC2.
In Switch mode, your ASC2 will respond to commands sent to “switch IDs” from your
remote. Up to 4 switches are supported on a single ASC2.
Base Address/TMCC ID
Each ASC2 on your layout needs a unique numbered address (a.k.a. TMCC ID). You’ll set
this “base address.” In switch mode, the ASC2 responds to four sequential IDs, starting with
the base address. In "Eight ID" accessory mode, the ASC2 responds to eight sequential IDs,
again starting with the base address.
Switch Sub-Mode: Momentary vs. Constant/Latching Operation
Lionel FasTrack and similar quick-throwing switches should use momentary operation.
Tortoise-style, slow moving switches should use "constant power" or "latching" operation. You
cannot mix latching and momentary switch operation in a single ASC2. Refer to the manual
for your switch if you are unsure which mode to use. Choosing the wrong mode can prevent a
switch from throwing, or permanently damage it.
Constant/Latching operation is also appropriate for signal controlled lighting where it is
necessary for power to be on continuously.
Accessory Sub-Mode: Eight IDs
Eight ID sub-mode should be used when a combination of lights and accessories are
connected to your ASC2. In this mode, each light or accessory will have its own TMCC ID.
Relay terminal #1 will respond to the base address ID and each subsequent terminal responds
to the next-higher ID number.
Eight ID sub-mode allows both momentary and latching relay operation. For momentary
operation, pressing AUX1 turns on that relay terminal as long as you hold the key. Pressing
AUX2 latches that relay on and it remains on after the AUX2 key is released. The next AUX2
key-press turns it off.
Accessory Sub-Mode: Single ID
Single ID sub-mode is designed specifically for connecting uncoupling tracks to a single
ASC2. In this case, only one TMCC ID is used and relay operation is always momentary. You
should choose Single ID sub-mode when ONLY uncoupling tracks are connected to your ASC2.
Configuring Your ASC2

17
To configure your ASC2 for ACCESSORY Operation:
1. Turn power to your command base and LCS system on.
2. Press and hold the ASC2 PGM button for 1 seconds. The red LED will begin blinking slowly.
3. On your Lionel cab remote, press ACC to choose Accessory configuration.
4. Enter the 1 or 2 digit base address/TMCC ID.
5. Press SET. The red LED will blink quickly, then return to slow blinking.
At this point, you've configured your ASC2 for Accessory operation and set the base TMCC ID.
Now you need to set the accessory addressing mode—8 ID's or single-ID sub-mode.
6. Press AUX1, then 0 for Eight ID sub-mode OR AUX1, then 1 for Single ID sub-mode (see
Accessory Mode sections on the previous page for more information). The red LED will stop
blinking and the configuration process is complete.
Configuring & Using ASC2 in Accessory Mode
Configuring Your ASC2
To operate your ASC2 in ACCESSORY, 8 ID sub-mode:
1. Press the ACC button on your remote
2. Enter the ID number matching the address range set in the configuration step above. Hint:
this will be the base address or one of the next seven numbers)
3. Press AUX1 to activate the associated accessory on a momentary basis, holding AUX1 as
long as you desire to keep the accessory operating. (If you are close to your ASC2, listen for
the sound of the relay clicking on and off.)
4. Press AUX2 to toggle the associated accessory on and off (like a light switch that you'd
leave on indefinitely).
To operate your ASC2 in ACCESSORY, Single ID sub-mode:
1. Press the ACC button on your remote
2. Enter the ID number matching the base address set in the configuration step above.
3. Press AUX1, then numeric 1 to 8. The number entered will cause that relay terminal to
operate momentarily, turning briefly on, then back off automatically, regardless of how
long you hold the button.
Single ID sub-mode is specifically designed for controlling multiple uncoupling tracks.
See Appendix for additional ASC2 configuration examples.
Additional commands
The ASC2 will identify by holding the numeric “0” (Legacy “R”) command by turning on
the RED PDI activity LED. This identifying mode will only work on the first ID in the 8 ID
sub-mode of operation.
The ASC2 will turn off all outputs if a numeric “0” (Legacy “R”) command is received.
The ASC2 will turn off all outputs if a “System Halt” command is received. Use the HALT
button only in emergency situations.

18
To configure your ASC2 for Switch (a.k.a. Turnout) Operation:
So far you've configured your ASC2 for Switch operation and set the base TMCC ID. Now you
need to set the switch sub-mode—momentary or latching.
6. Press AUX1 for momentary OR press AUX2 for latching operation (see Switch Sub-Mode:
Momentary vs. Constant/Latching Operation for more information). The red LED will stop
blinking and the configuration process is complete.
Lionel FasTrack and similar quick-throwing switches should use momentary
operation. Tortoise slow moving switch machines should use "constant power" or
"latching" operation. You cannot mix latching and momentary switch operation
in a single ASC2. Refer to the manual for your switch if you are unsure which
mode to use. Choosing the wrong sub-mode can prevent a switch from throwing, or
permanently damage it.
To operate your ASC2 in SWITCH mode:
Note!
1. Turn power to your command base and LCS system on.
2. Press and hold the ASC2 PGM button for 1 seconds. The red LED will begin blinking slowly.
3. On your Lionel cab remote, press SW to choose Switch configuration.
4. Enter the 1 or 2 digit base address/TMCC ID.
5. Press SET. The red LED will blink quickly, then return to slow blinking.
1. Press the SW button on your remote
2. Enter the ID number matching the address range set in the configuration step above.
(Hint: this will be the base address or one of the next three numbers)
3. Press AUX1 to set the track switch/turnout to THRU (aka straight) position. Press AUX2
to set the track switch/turnout to OUT (aka turn) position.
Configuring & Using ASC2 in Switch Mode
Configuring Your ASC2

19
Accessory examples
This section of the manual describes configuring the ASC2 for operation of up to 8 individual accessories.
Your ASC2 must be configured either as a switch controller OR an accessory
controller. It cannot control switches and accessories at the same time.
Basic on/off accessories and layout lighting can be connected to the Accessory/Switch
terminals on the ASC2. In Accessory mode, up to 8 different devices can be connected. Refer to
Figure 8, letter B. The row labeled “Accessory” shows which terminals correspond to accessory
1 through 8. Accessory 1 through 4 share one common connection and 5-8 share another.
Keep in mind that the ASC2 does not supply power to the accessories; this device simply
acts as an ON/OFF switch. It is recommended that the ASC2 COMM connection be used for the
“hot” leg of your external power.
To connect a basic on/off accessory or light to your ASC2:
Note!
1. Attach one wire to the Power/A terminal on your power supply and connect it to the COMM
terminal of the ASC2.
2. Attach another wire to the Common/Ground/U terminal on the power supply and connect
to an accessory power terminal.
3. Attach a final wire to the remaining accessory power terminal and connect it to a numbered
terminal on the ASC2 (terminal 1 shown in the illustration).
To operate your accessores in eight ID sub-mode, you will need to address each
connected accessory by its individual TMCC ID. Accessory 1's ID is equal to the
TMCC ID base address. Accessory 2's ID is equal to the base address plus one. See
Appendix A for additional accessory configuration and operation examples.
