Reefdosingpumps.com pump question...anyone using one of these ??

[officerbogus]

I just got a great deal on what I believe is the "sentry" model of peristaltic pump. The only thing is that I cannot seem to find an interface jack on the pump to use my RKL with it. It has two cords, one two prong and one Grounded, coming out of the housing.

How do I use this with my RKL?????? Do I use one or both of the cords, or is it not possible with my model ?

I have the Sentry unit, and use it with a top off controller. It needs the Controller Interface listed on this page to work:

I dont have an interface input on my pump for some reason.
