ASC2 Setup


This help page will teach you to configure an LCS ASC2 module from within the LCS App. If you have already configured your ASC2 using your Lionel CAB remote, this is an optional step. You will need a working ASC2 and one or more remote operating switches to successfully complete this operation. One ASC2 can control EITHER quick-throwing switches like Lionel FasTrack, OR slow-moving, Tortoise Switch Machines. Refer to your owner’s guides for more information.

ASC2 Composite 1a

One ASC2 can operate up to four track switches. These four switches will have four consecutive TMCC IDs. The lowest numbered ID is called the ASC2’s “base address,” and this corresponds to the first connected switch. Each subsequent switch has the next-higher ID number. Remember this important point when mapping track switch icons in a Custom Control Panel to your ASC2.

Example 1: Setting The First Switch ID

Setting the first switch ID also sets the base address of the ASC2. To configure the first switch connected to an ASC2:
  • Press the Program/PGM button on your ASC2 until the red LED begins blinking.
  • Select a track switch in the currently open Custom Control Panel.
  • Touch the Gear/Info button.
ASC2 config 1 gear
  • The switch configuration panel appears. The first time you configure a switch it defaults to basic TMCC operation, and looks like this:
Switch gear TMCC setup screen
  • The TMCC option lets you revert to basic operation for the selected switch icon. But we’re configuring it for ASC2, so…
  • Touch the TMCC CAB Remote image with one finger and swipe from right to left. The ASC2 configuration panel slides into view.

  • Choose the ASC2 TMCC ID/Base Address using the large three digit display.
  • Tap each digit to set your desired TMCC ID.
  • Press the “Set ASC2 ID” button.
  • The blinking red LED on the ASC2 will turn off and the operation is complete.

Example 2: Setting Four Switch IDs

This example shows setting of the first switch ID (this time to ID 40), then shows the setting of three additional switches.

To configure an ASC2 with four track switches:
  • Press the Program/PGM button on your ASC2 until the red LED begins blinking.
  • Select the switch icon representing the first track switch connected to the ASC2.
  • Touch the Gear/Info icon to open the ASC2 configuration panel.

  • Choose the base address by tapping the digits, then press the “Set ASC2 ID” button.
  • The blinking red LED on the ASC2 will turn off and the base address is set.
  • Select the next switch icon.
  • Tap the Gear/Info button.
  • Swipe to reveal the ASC2 Configuration panel.
  • Assign it the next consecutive TMCC ID number.
  • Repeat for the remaining switches.

  • Do not press the Set ASC2 ID button when setting ID’s for switches two through four. Doing so will generate an error message, as the ASC2 is not in Program mode.

Momentary vs. Latching Switch Type


The ASC2 can control quick-throwing switches like Lionel FasTrack, or slow-moving, Tortoise Switch machines. It is absolutely necessary that ALL FOUR SWITCHES connected to one ASC2 are of the same type! The ASC2 “Latching” mode is ONLY for use with Tortoise switch machines. Using Latching mode on FasTrack switches can cause permanent damage to the switch! Refer to your owner’s guide for more information.
ASC2 config TYPE button
To configure an ASC2 for Tortoise Switch machine operation:
  • During the programming process for the first connected switch (see above) tap the double-triangle “Type” button.
  • The Type will change to “Latched” and a warning will be displayed. Remember, selecting Latched mode on a FasTrack switch can cause permanent damage to the switch mechanism! The Type setting applies to ALL FOUR SWITCHES connected to this ASC2, not just the one switch selected in your custom control panel. See your ASC2 Owner’s Manual for details.
  • Click OK if you’re confident that ALL FOUR SWITCHES connected to this ASC2 are Tortoise.
  • Press the “Set ASC2 ID” button.
  • The blinking red LED on the ASC2 will turn off and the operation is complete.

Switch ID’s above 99


The ASC2 may be configured to operate momentary or latching switches with addresses from 0-99 using your Lionel CAB remote. However, using LCS App, you can program the ASC2 to use TMCC IDs up to 250. This is an obvious benefit for layouts with more than 99 switches. However, note that Lionel CAB remotes are only able to address switch IDs up to 99. Therefore, setting an ASC2 TMCC ID/Base Address higher than 99 means only the LCS App (and future LCS-aware software) will be able to operate those switches.
