Add DCS with wy-fy only

A WIU connected to a TIU.

Do you use the z4000 remote commander to control your Z4000 with your DCS remote.
I am assuming not but if you do, the WIU is not able to communicate with the Z4000 to remotely control its functions. The Z4000 will have to always be operated manually to raise and lower the track voltage. The TIU can still "kill" the track voltage using the E-Stop button.

If your TIU is older than Revision L without the USB port, you will also need a USB to DB9 SERIAL adapter. These can be had at Amazon pretty cheap.

OK, thanks a few questions:

If I get the Z4000 remote commander will I be able to not have to set the handles each time?

The two loops are completely separate. Do I need two TIU/WIU combinations or just one?

I am not using any command switches or accessories, just engines. Is the procedure as simple as:

a. Connect 18v to the track

b. Connect the re and black from the TIU to the track terminals

c. Connec the WIU to the TIU

d. Connect the iPhone to the wy-fy netowork

e. Run trains

What other steps are involved?

thanks

Frank, You Nailed it dead on with your list. That's it! Maybe buy the standard Version of the app for $4.99 so that you have full control over all engines. The free app only allows limited control over 3 engines at one time.

When using the remote commander, you will leave the Z4000 handles set to zero and never touch them. The transformer will always start at zero volts, and you use your DCS remote or the Z4000 remote commander remote to dial the voltage up to the desired level.

Frank, I'll also add this to my post above.

Your method would put the TIU in "Passive Mode" which does not allow the TIU to exclusively control the track voltage independent of your Z4000.

I would run it in "Active Mode" by connecting the Z4000 to the "FIXED 1 INPUT" on the TIU and connect the "FIXED 1 OUTPUT" to the track.

Connect the second handle of the Z4000 to "FIXED 2 INPUT" on the TIU and connect the second loop to the "FIXED 2 OUTPUT".

This will allow the E-STOP button to function correctly and let the TIU shut off the power to the tracks when there is a problem.

Thanks, does anyone have the part number for the Z4000 remote control?

thanks
