You should be getting some signal unless...

Your tiu is in the off state,The tiu must be turned on using power to fixed 1 or an aux power5 supply. Is the red LED on top of the tiu lit? Fixed 2 is a straight through connection, if the tiu was in the "off" state, there would be no dcs signal but power to the track.

The signal somehow got turned off, check with... menu/System/DCS set up/ AON..(turns the signal on to all channels)

You have the track wires reversed, Red must always go to the center rail, black to outside.

You have a faulty TIU.. Tiu version I3a had serious signal problems, Look at bottom of tiu for version.

Place magic bulb on terminal block... Hopefully this helps.
