Alesis Sample Pad Pro - Hi Hat Pedal Trouble

I purchased the (Yamaha HH65 Hi Hat controller) and the (Yamaha KP65 Kick Tower) for my Alesis Sample Pad Pro. The kick trigger is working great, but the hi hat pedal is not getting any type of signal in the hi hat jack.

Strangely enough, the kick trigger (which is working) is also not getting a signal in the hi hat jack. AND when i plug in the hi hat pedal to the foot switch, it functions correctly in "stop all" which cuts off the sound being signaled from any trigger.

Is there a reason this hi hat pedal (which is excellent quality I might add) might not be working? Or why I cant get the hihat jack to work with the kick trigger that is working?

Please Help
