Abstract

This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid, a wireless communication port, a controller, and a housing to enclose the apparatus. The controller is configured to communicate with a second device via the communication port using an open standard wireless communication protocol. The housing includes a mechanical coupling to slidably engage the second device which includes a second wireless communication port. Slidably engaging the second device positions the first and second communication ports opposite each other to allow communication via the first and second communication ports when slidably engaged.
