Compatible of ASC2

I’m pretty sure that the ASC2 being part of the LCS system requires a Legacy base or Base1L or a Wi-Fi module and a LCS App.

Page 8-11 explains the different options.

Thanks for the reply

i was hoping to keep TMCC

The ASC2 communicates on the PDI bus that uses RS232 serial comms at 115.2 Kbaud and wraps TMCC commands with the PDI protocol framing.  In contrast, the TMCC Command Base serial comms are 9.6 Kbaud and transmits un-framed 24-bit TMCC commands.  The comms are NOT compatible.

A solution is the LCS SER2 which provides RS232 comms at 9.6 Kbaud to send/receive 24-bit TMCC commands over the PDI bus.  The SER2 is the recommended method to connect older ASCs and other pre-LCS devices like TPCs to the PDI bus.  It is also used for connecting a DCS TIU to the Legacy base via the PDI bus.  Connecting the Command Base to the SER2 should send 24-bit switch and accessory commands to the ASC2 modules on the bus.  I have used the LCS WiFi in "No Base" mode and all the LCS modules on the bus are operational, but I have not experimented with the PDI bus with no Legacy base connected and no WiFi module - i.e just SER2 and ASC2 modules on the bus and the Command Base connected to the SER2.  If you already have the ASC2 on hand, get a SER2 and see if it works.  (I would try it out but I'm away from my LCS gear for the holidays).  If it works OK, then you need just one SER2 to handle multiple ASC2 and other modules on the bus.

Great reply..... now I get it
thanks
