 Yes, it's page long question guy again. I have discovered 4 OTC units in my stock, and need to determine whether they are of use to me.  My TMCC setup consists of  3 TPCs, 1AVC, 6 bpcs and 3 ascs.  I have heard that I may be near the limit of devices a single command base can control.  Obviously, if that is true, I would probably not be able to add 4 otcs to the load, and may be forced to use the mechanical controllers for my operating/uncoupling tracks until Lionel actually markets their signal booster to increase my capacity to add devices.  For purposes of load calculation, I rarely change the settings or turn blocks on or off.  Two of the three TPCs are heavily used to control track voltage in conventional mode. The other TPC and the AVC are sparsely used.  The ASCs get the highest volume of use.   If the feeling is that I can add the otcs, I will be back with some questions I have about their operation, but for now, just want to find out if I can use them at all.

Thanks for responding.  Would really like to have some input about the load  on the command base before doing all the extra wiring to install the OTCs. 

The OTC manual is pretty strange.  It specifies a separate transformer to power the OTCs, "Do not connect the common from the U OTC terminal to the outside rail".  Does that mean I cannot connect to the common ground loop that serves the entire layout?

  I,m not hot on using SCIIs for this project.  Have one not working right already, and have generally found that the IC Controls developed nare more robust and reliable.
