Overview
IOT is a fairly straight-forward interface, with a few things to note.
Most IOT designs use the BRS request to determine the optimal base curve to use. The exception are the Camber designs, where IOT will provide base curve charts; these must be set up in Rx-Universe and the lens style(s) set to use the Camber chart.
IOT does support the use of blocked prism, so they will send back the KPRV? labels in the LMS file. If blocking prism is not desired, be sure to set the "Blocker maximum prism" field on the "DS" record for IOT to 0, to suppress this.
Camber Designs
The Camber designs require a few things to be set differently. First, Camber designs do not use BRS request, but rather base curve charts which are provided by IOT. These charts must be set up in Rx-Universe by the lab, and the lens style set to use the appropriate chart. For example, if the chart is set up using chart "CA", then the lens style must be set to use that chart; on the lens style General tab:
