Proform 1850 Treadmill + GEM Retro + Zwift

Hi everyone,
I just read that a device called GEM Retro can be connected to a CSAFE port on a treadmill in order to send the speed/incline information to Zwift. Does anyone know if the model mentioned above has a CSAFE port installed?

Thank you for any information,

Not sure about that model, but my ProForm Pro 2000 does not have the CSAFE port.

You might want to contact ProForm support for a definite answer.
