Congratulations
Congratulations on your purchase of the Lionel TrainMaster SC-2 Switch and
Accessory Controller! With this device you can experience the benefits of TrainMaster Command Control when operating your switches and accessories with your CAB-1 Remote Controller.
The SC-2 listens for and responds to switch (SW), route (RTE), and accessory
(ACC) commands from your CAB-1 Remote Controller and Command Base.
You may choose to operate your SC-2 in its standard configuration or in either of the two alternate modes. The standard configuration controls four switches and four accessories. When operating in the alternate modes, you may control up to six switches, or twelve acces-sory actions.
A CAB-1 Remote Control (6-12868) and a Command Base (6-12911) are required to operate the SC-2. Find them both at your authorized Lionel dealer.

Each SC-2 can control switches and acces-sories through commands from the
CAB-1 Remote Controller and Command Base. All SC-2 outputs are rated for 15 amps and can control most switches and accessories directly. Use the sheet of labels (included) to identify the SC-2 ID#’s on your switches and accessories.
The SC-2 has a built-in antenna to receive signals from the TrainMaster Command Base. Place the SC-2 anywhere near track connected to a Command Base, and it will receive its commands.
There are three sets of terminals on the SC-2. Within each terminal block are an upper and a lower row of three set screws. The center screw of each group is for the transformer Common/Ground/U or Power/A terminal, depending on the application. The left and right set screws are wired to a switch or accessory to activate it. When a terminal is programmed to control a switch, the opera-tion will be momentary. If the terminal is set to operate an accessory then you may select AUX1 for a momentary operation or AUX2 to
toggle the accessory on or off. Refer to Figure 1 on page 5 to identify the arrange-ment of the terminals.
The SC-2 is designed for three operating modes:
1. Control four switches through the left and center terminal blocks. Control two momentary and two on/off accessory func-tions through the right terminal block.
2. Control six switches using all three terminal blocks.
3. Control six momentary and six on/off accessory functions using all three terminal blocks.
To connect a switch or accessory to the SC-2, use a screwdriver to loosen the set screws on the terminal, then insert a stripped wire in the opening directly beneath the set screw and tighten the screw. Refer to Figure 2.
You do not need to remove the screws.

Powering your SC-2
Installing the SC-2 on your railroad
There are three ways to power the SC-2. The type of devices connected to the SC-2 deter-
mines which of these options will work with your application. The SC-2 requires 7-20 VAC to operate correctly, and a fixed voltage source is required. When powered correctly, the green light on the SC-2 will illu-minate.
All switches and accessories must be powered by a separate power supply. This power supply must not be used to power the track.
If you use the SC-2 to operate at least one switch, the power can be supplied through the switch itself. No special wiring is needed; however, one of the switches must be properly connected to the Switch #1 terminals at the upper left. These terminals are labeled “1” in Figure 3.
Do not use the wall pack or the separate power terminals on the SC-2 if you are using it to operate switches.
If your SC-2 serves only as an accessory controller (no switches are connected), you must power the controller with the included Lionel AC wall pack or through track power. Do not power the SC-2 with both the wall pack and through track power.
To use the wall pack, simply plug the cord into the socket in the back of the SC-2, then plug the wall pack into the wall.
To use track power, attach a wire to the outside rail or to the #2 terminal on a Lionel Lock-On, and connect it to the top power terminal. This is the Common/Ground/U terminal. Attach another wire to the inside rail (the #1 terminal on a Lionel Lock-On) and connect the powered rail to the bottom terminal. These terminals are labeled “3” in Figure 3. Also, you can use these terminals to attach a separate transformer directly to the SC-2.
To use track power, you must be operating in Command mode so that the track voltage is constant. Varying track voltage will cause erratic operation of the SC-2.

Connecting Lionel switches to the SC-2
Installing the SC-2 on your railroad
Connect three switch wires to the SC-2 terminals. Begin with the ground
(common) for each switch. Listed below are ground terminal locations for some popular Lionel switches. Connect the ground terminal of each switch to the center screws of each terminal block on the SC-2.
HOW TO FIND THE RIGHT POST
If you’re in doubt about which binding post connects to the outside (ground) rail, check it with a meter or continuity tester, available from your local electronics supply store.
• On contemporary Lionel O gauge switches (6-23010 and 6-23011), ground is terminal number 2. Refer to Figure 4.
• On postwar 022 and MPC/early LTI O gauge switches (5132 and 5133), O-31 (14062, 14063) and O-72 (65165, 65166) ground is the center binding post. Refer to Figure 5.
• On many O-27 switches, including the O-42 and O-27 versions sold in the 1950s (1122 and 1122), and during the modern era (5121 and 5122e), ground is closest to the switch motor. See page 10 for special instructions for using O-27 with Command control. Refer to Figure 6.
• On super O switches (where two posts are together and one post is positioned on the side) ground is the side post.
Each of the SC-2’s ground termi-nals are independent of all other ground terminals. You must connect a ground wire for each device to the center set screw on that terminal.
When connecting the left and right terminal wires, make sure the wire throwing the switch “out” (curved) connects to the SC-2’s “Switch Out” terminal (#3). The wire throwing the switch “through” (straight) should connect to the SC-2’s “Switch Through” terminal (#1).
To identify which wire controls which switch function, begin by powering up each switch. Touch each of the two remaining switch wires to its ground terminal and note the action of the switch. Once the functions have been determined, power to the switch should be disconnected until the wiring to the SC-2 is completed.
When a switch is properly connected to the upper left terminals on the SC-2 and switch power is on, the SC-2’s green light should illuminate. This indicates the SC-2 is properly powered.

Installing the SC-2 on your railroadModifying O-27 switches for use with the SC-2
O -27 type switches receive their power from variable track voltage. In order to operate
this type of switch with the SC-2 controller, you need to make the following modifications to allow the switch to operate from a fixed voltage power source.
First, take the top cover off of the switch by removing the screw. This will expose the double coils. Next, find the two wires that are located at the center of the two coils. These wires are contained inside one piece of insula-tion. Gently pull on the insulation to expose the wires. Now, clip the two wires about 1/2˝ from the coils. Using electrical tape, wrap the wire ends that come up from the bottom of the switch. Use the heat from your soldering iron to remove 1/4˝ of the varnish insulation from the remaining wires, then twist the wires together. Using your soldering iron, put a
small amount of solder on the ends of these wires and solder a jumper wire to them. Wrap this connection with electrical tape to keep it from coming in contact with the coil housing.
Before you replace the switch cover, you may need to cut a notch (using a hobby knife) for the wire to come through. You may also route the wire through the holes used to vent any heat generated by the coils on top of the cover. Replace the cover on the switch, then attach the jumper wire to a fixed voltage power source.
You will need to attach a ground wire from this separate power source to the outside rail of your track, or you can attach this ground wire to the “U” post on the PowerMaster.
Your switches can now be operated using the SC-2 Controller.

Programming the SC-2 switch numbers
Every switch needs an ID#. Take the time now to label your switches and
the terminals they connect to on the SC-2. Start numbering with #1 on the first SC-2 at the upper left corner. Follow the numbering scheme shown in Figure 1 on page 5.
SC-2 switch numbers are consecutive. Only program the first switch position on each SC-2. The next switch ID#s are programmed automatically by the SC-2.
For example, if you program the first switch connected to your SC-2 as switch #1, the switch numbers on that SC-2 become 1, 2, 3, and 4 (1 through 6 if programmed to control switches only). If you program the first switch connected to your SC-2 as switch #9, the numbers become 9, 10, 11, and 12 (9 through 14 if programmed to control switches only). See page 22 for instructions to program the SC-2 in switch
only mode.
Choose switch numbers between 1 and 99 (99 switches total). ID# 0 is reserved for clearing
the settings.
To program the switch numbers, be sure the Command Base and SC-2 are both powered up. Slide the SC-2 RUN/PROG switch (see Figure 9) to PROG. Press SW, the switch ID#, then SET. The SC-2’s red light will turn on for two seconds. Now slide the RUN/PROG switch back to RUN.

Controlling switches with CAB-1
N ow that you've programmed the switch numbers, you can throw
the switches using the CAB-1 Remote Controller.
To operate another switch, you can just enter the ID# and select OUT or THROUGH without pressing SW again. This "short-hand" continues to work until you press another top-row address button (ENG, TR, ACC, RTE).
If the switch operates but throws to the wrong position, swap the wires connected to the outer set screws of the SC-2 termi-nals for that switch.

Creating routes around your railroad
Here’s a common scenario: to travel from the main line to the yard, you must
travel on a certain route. In Figure 10, for example, Switch #2 is THROUGH (straight),
Switch #4 is OUT (curved), and Switch #14 is THROUGH. With TrainMaster Command, you can throw all those switches with a single command—RTE.
Always check your RTE programming. Throw switches opposite the RTE direction, then press RTE and the ID#. Your route should immediately throw. To avoid overloading your power supply, switches in a route will operate in consecutive order, one at a time.
You can add more switches to a route at any time.
Any switch can be part of any route. A route may consist of any number of switches, although each switch may only be used once in the same route. Any switch can be included in any number of routes, creating a wealth of possibili-ties. Discover new pathways around your railroad with RTE. Routes are remem-bered forever—or until you clear them.

You may find it helpful before program-ming routes to make a list of all your
switches and their settings for each route. Refer to this list when programming and to identify routes later.
When a route is activated, there will be a delay between the activa-tion of each switch.
The SC-2 can control a maximum of nine
routes. When assigning a route ID#, choose a number between 1 and 9. Refer to the example below to create a route.
All SC-2’s must be on with the RUN/PROG switches in the RUN position during all route programming. The route will activate every time RTE and the ID# is pressed during program-

Note!
Note!
Note!
You cannot remove an individual switch from RTE; you must clear the entire route and start again.
If you make an error during RTE programming, do not press SET. You must start over—press RTE, Route #, the switch number, its position, and then press SET.
1�
Select any route you’ve programmed by pressing RTE and entering the RTE
ID#. Make sure you press and hold the ID# button for one full second. This ensures the command is issued to every SC-2 on your railroad.
When you are pressing the ID# button, some of the switches may not actually throw until you’ve released the button. Switches activate at different times once you’ve selected the route —this keeps your system (and your railroad’s power supplies) from overloading due to simultaneous activation.
Be sure to let one route operate completely before selecting another. This will ensure trouble-free operation of the SC-2’s.
Unlike switch control, there is no “shorthand” for route control. Each time you wish to activate a route you must first press the RTE key. This must be done even if the last command issued was a route activation.

Activating routes
After a route is programmed, you may reprogram an individual switch setting
by following the steps on page 16. The existing switch direction assignment (AUX1 or AUX2) will be reassigned.
You cannot delete individual switches from a route assign-ment. You must clear the entire route and reprogram.

Operating accessories with your SC-2
Most Lionel accessories can be controlled by an SC-2. Start by
sequentially numbering the accessory termi-nals with the adhesive labels (included). Refer to Figure 11 for proper numbering order. Each accessory ID# can be used for either momentary or on/off functions. For any given accessory number, press AUX1 for Momentary operation of loaders and similar products or press AUX2 to toggle the acces-sory functions such as lights. Turn to pages 28-35 for wiring examples.
Keep in mind that accessories need to be externally powered. If the SC-2 will only operate accessories then you must either power the SC-2 through the track auxiliary power connection terminals or by a wall pack. Operating accessories may be powered by PowerMasters. This gives you keypad control over their voltage levels. See your Command Control instruction manual for details.

Controlling accessories with your CAB-1
N ow that you’ve programmed accessory numbers, you can
activate the accessories using the CAB-1 Remote Controller.
You may wish to create a list of your accessories, their ID#’s, and whether AUX1 or AUX2 should be used to control them. Use this list while you learn to use the SC-2 to help you operate your accessories correctly.
When the SC-2 is powered up, it will resume the last operating state for each accessory. In other words, if an accessory is on when power is switched off, the next time power is turned on, that accessory will be switched on.

The SC-2 allows you to program it to operate one type of device only. For
example, you may choose to connect all your switches to one SC-2 and all your accessories to a second SC-2.
If you plan to use this SC-2 to control switches only, you may wire up to six switches to the controller, making use of all of the terminals. Wire the switches as described on pages 8-12. Once all connections have been made, turn on the power to your switches. The SC-2’s green light should come on to indicate it is powered. Now the unit must be programmed to control six switches. Follow the example to set the SC-2 for switch only mode.
If you decide to reprogram an SC-2 from standard mode to accessory only mode, all route assignments on that SC-2 will be cleared.

If you plan to use this SC-2 to control accessories only, you may wire twelve accessories functions to the controller, making use of all of the terminals. This mode gives you six momentary and six on/off controls. Wire the accessories as described on page 19. When the SC-2 is wired to operate accessories only, a wall pack may be used, or the SC-2 must be wired to the track or an auxiliary power supply. Once all connections have been made, plug the power cord from the wall pack into the SC-2 and plug in the wall pack or turn on track power. The SC-2’s green light should come on to indicate it is powered. Now the unit must be programmed to control twelve accessories (six Momentary and six toggle on /off functions). Follow the example to set the SC-2 for accessory only mode.
If you decide to reprogram an SC-2 from standard or switch only mode to accessory only mode, all route assign-ments on that SC-2 will be cleared.

TroubleshootingReplacing the fuse
The controller is protected by an internal fuse. If your SC-2 stops operating, first
check your wiring to be certain you have not wired the SC-2 incorrectly. Also, be certain that no wires have come loose or are broken. Check that your switches are powered. If a wall pack is being used, check that it is firmly plugged into the back of the SC-2. If the green light on the SC-2 is still out, then the fuse probably needs to be replaced.
To replace the fuse in the SC-2, discon-nect the power from the controller, and turn off all power to your railroad. Next, remove the four screws in the corners of
the plastic case (see Figure 12). Carefully remove the bottom cover from the SC-2. DO NOT TOUCH ANY OF THE ELECTRICAL COMPONENTS INSIDE. THEY ARE STATIC SENSITIVE AND COULD BE DAMAGED. The fuse is located near the power plug on the back side of the case. Carefully pull the fuse out of its holder (a fuse puller is recom-mended).
Replace the fuse with a 2 X 5mm barrel type 1.5 Amp fast acting fuse. These are available from automotive and electronic suppliers.
Press the fuse into its holder, then replace the plastic base and the four screws.
Fuse 4 screws
Figure 12. Fuse replacement
Troubleshooting
Everything is connected but nothing happens.1. Check all wiring to switches. Check that the switches are powered and a switch is connected to
the SW 1 position. 2. If using a wall pack, check that it is connected to the SC-2 and plugged into a powered wall
outlet.3. If you are powering the SC-2 from the track, be sure track power is on and connections to the
track are secure. PowerMasters should be switched to Command mode and switched on by pressing TR, ID#, then BOOST.
4. Check the fuse in the SC-2 and replace if bad. 5. Use a test light to check for power. The SC-2 requires 7-20 V AC to operate properly.6. If the SC-2’s green light still does not illuminate, contact your Lionel Authorized Service Station
for assistance.
The SC-2’s red light does not blink when I send commands from the CAB-1 Remote Controller.1. The SC-2’s red light will only blink when you enter a RTE, SW or ACC command with an ID# of
one of the devices connected to that SC-2.2. Check to be sure the Command Base is plugged in and that its red light blinks when a command
is issued from a CAB-1 Remote Controller. The Command Base must receive the signal from the CAB-1 in order for the command to be passed to the SC-2. See your TrainMaster Owner’s Manual for additional information.
3. Try repositioning the SC-2 closer to the track or Command Base. The communications signal from the Command Base may be impeded by structural or electrical elements in the area. Be sure the SC-2 is not sitting on a metal surface.
4. Ensure that the Command Base is properly connected to the track or track power supply. See your TrainMaster Owner’s Manual for additional information.
5. Turn off all other electronic devices in the area. They may interfere with the Command Base communication signal.
When I operate a switch, it throws the opposite direction.Reverse the wires from the switch attached to the outer (left and right) set screws of the SC-2
terminal block, or at the switch.
When I operate an accessory it operates continuously when it should shut off.
Accessories connected to the SC-2 will respond to the AUX2 ON/OFF command when connected to the right and center set screws of a terminal block. For momentary control, connect to the left side of the terminal block and use the AUX1 momentary command.
When I operate an accessory it operates briefly then stops.Accessories connected to the SC-2 will respond to the momentary AUX1 command, when
connected to the left and center set screws of a terminal block. For on /off operation, connect to the right and center set screws and use the AUX 2 on/off command.

Answers to questions
I connected my SC-2, but I can’t get the switches to throw.1. You must program the SC-2 with switch ID numbers before you can use the SC-2 to operate
switches.2. Verify the switches are connected properly and the SC-2’s green light is on.
I connected my SC-2, but I can’t get the accessories to operate.1. You must program the SC-2 with accessory ID numbers before you can use the SC-2 to operate
accessories.2. Verify that the accessories are connected properly and the SC-2’s green light is on.3. Accessories connected to the left side of a terminal block will only respond to AUX1 momentary
commands. AUX2 on/off commands only control accessories connected to the right side of a terminal block.
I programmed my switches and accessories on the SC-2 but now I can’t remember their ID#’s!1. Place numbered “flags” or stickers at each switch and accessory. This will help you learn their
numbers; later, you can remove them. You may also choose to draw a layout diagram and label ID#’s there. Small localized diagrams positioned around a large layout may also help.
2. Switch and accessory ID#’s are consecutive for each SC-2. Try activating each ID number in order and watch to see what device operates.
3. ID#’s may be reprogrammed at any time. If you can’t easily determine which switch and acces-sory numbers have been used, you may reprogram ALL the SC-2s with new numbers. Be sure to label all switches and accessories. You will have to clear and reprogram all route assignments too with this method.
I incorrectly entered some information when programming a RTE. What should I do?
Making errors during route programming is no big deal. Just remember that as long as you don’t press SET, you haven’t programmed anything. Start over at the RTE command for that switch: RTE, route ID#, switch number, the direction you want to throw (AUX1 or AUX2), and finally, SET. Pressing SET commits the command string to memory. If you pressed SET already, read on.
I added a switch to a route that I don’t really want. How can I remove it?You must clear the entire route and reprogram it. Press RTE, route ID#, SET. This erases all switch
assignments in that route.
Only one switch will operate from the SC-2.Check the connections to all other switches wired to the SC-2. Unlike the previous version of
this device, the SC-1, the common terminals on the terminal strips are not tied together. You must connect a common lead to each terminal on the SC-2.
Can I operate switch machines and devices by other manufacturers with the SC-2?
The SC-2 can control any low voltage momentary or ON/OFF device through its terminals as long as the current does not exceed 15 Amps.
