For full functionality, LCS equipment will be connected to the DB9 serial port on your command base. If you currently have TPCs or other devices hooked up to that port, you must remove that cable to make way for the LCS Power Supply and DB9 cable. Adding the SER2 gives you a new DB9 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 Lionel CAB remotes and/or the LCS App+LCS WiFi. It is connected to the LCS system using an LCS PDI cable. This cable carries commands as well as power for the SER2's control electronics.
You can connect multiple SER2 modules if desired; each adds an extra DB9 serial input/output connector to your LCS system.
One 6-81499 LCS Power Supply and DB9 cable is required per LCS installation.
