Zoom with Sarix IMP1110-1ER

mplement Zoom control using Pelco API

We are testing our integration with a Sarix IMP1110-1ER but we are not able to control ZOOM ( this feature is available from camera webpage).
According to http://pdn.pelco.com/content/pelco-api-web-services-supported-pelco-products IMP Series doesn’t support Lens Control .
Can you clarify how we can implement Zoom control using Pelco API ?
