Elinchrom & Speedlite Simultaneously

I was trying to use my Elinchrom BX 500 Ri & Canon Speedlites simultaneously using:

(1) Elinchrom EL-Skyport wireless trigger to trigger the Elinchrom lights

(2) Pocketwizard Flex TT5 to trigger the Canon Speedlite 600RX

To do so, the TT5 was placed over Canon 60D and the EL-Skyport over the TT5. unfortunately, I could not succeed to make the Elinchrom work.

Contacting the pocketwizard support, had been informed that sometimes it can work, sometimes it is not & I can try to use sync cable.

Is there is anyone here, succeeded to make this configuration to work without using a cable?

Regards.
