Using Legacy and MTH DCS - Can the Y cable for LEGACY/TMCC be used to connect to MTH DCS

You'll need an LCS SER2 module for this. The Legacy Y cable won't work. Here's a link to the SER2 manual (see page 13):

Thank you.

I printed out a set a made a file also.

Thank you,John

Rudy,

Correct me if I am wrong, but he need's the LCS WiFI module and leaves the other half of the Legacy Y-Cable attached to the TIU via the MTH adapter cable.

This will enable layout switch/turnout control with the iPad LCS app and train operation with either Legacy Cab-2 or MTH DCS Remote.

Page 9 of the instructions, replacing TMCC base with MTH base.

(see attached LCS WiFi instructions)

The "other half" of the Y cable is strictly for the CAB1 base if you choose to use it.  He will need a WiFi module and power supply cable (6-81499 LCS DB-9 Cable with Power Supply) but also the SER2 to connect the MTH TIU.  The power supply cable would plug into the portion of the "Y" that would of formerly gone to the TIU (serial comm)before the LCS system was introduced.  The TIU would then use the SER2 for its interface.

Thanks, Marty.

Thank you all very much!!

This is exactly what i need to know.

In my architecture i will simply daisy chain a pdi cable from my last lcs switch module to a lcs serial module then use the mth cable to connect the tiu.  I had previously removed the mth cable to connect the lcs db9/power/pdi cable to the cab2 unit.

Then i can run both mth and lionel trains from my mth handheld if i want. I did get my lcs wifi and ipad controlling the layout today with 4 switches.  I will add 4 more switches tomorrow and order a serial module. At one point the wifi connection on the ipad application was unstable but i have to use it more to see if that will be a persistant problem

Thanks again to all.
