LCS SER2 (Serial Converter, 6-81326) provides one or more DB9 serial connections to your LCS system. Use it to hook up older Lionel serial products or connect a computer to your layout.
SER2 lets you connect older Lionel/IC Controls products such as the TPC300, TPC400, ASC or BPC to a new LCS installation. For full functionality, LCS equipment will be connected to a PDI Port on the Base3. Adding the SER2 gives you a new DB-9 port to reconnect your old devices. SER2 also boosts the available serial data drive current, so you can connect all your wired serial devices without the need for a separate serial booster.
The SER2 will pass through commands from an original Lionel Cab1/Base1 to your Base3. Note that a null modem will be required to connect the Base1 to the SER2.
The SER2 also lets you connect your own DIY software to your train layout. Any computing device that can generate standard 9600 baud serial data can send TMCC and LEGACY commands to control your layout. All the info you need is in the free LEGACY Command Protocol document.
You can connect multiple SER2 modules if desired; each adds an extra DB-9 serial input/output connector to your LCS system.
