Support for the _MFRAM VCA tag for MEI engravers requires Rx-Inventory version 0.1.263 or higher.

This label allows MEI edgers to engrave a safety logo on the front of the lens. Using this tag, MEI will orient placement and chose the correct logo.

Usage

The first step for supporting the _MFRAM tag within RxUniverse is to setup a User Defined Field within Rx-Inventory for the concerned frames.

Within Rx-Inventory, open the details of a frame, and navigate to the User Defined Fields tab, at the bottom of the page.

Create a new User Defined Field for the _MFRAM value. This field will be present on all frames, and you can freely add that needed values on each frame.
To add a value to multiple frames at once, utilize the mass update functionality on the frame index page. You must initially create the _MFRAM User Defined Field at least once to use the mass update functionality.

In this example, we set the frame(s) to have an _MFRAM tag with a value of “ABC”:

On the RxUniverse side, you must add entries to the Device Interface Params, VCA Label Table, and VCA Label Table Settings.

In The VCA Label Tables, add an entry for your device and _MFRAM VCA label

In VCA Label Table Settings, add an entry for the _MFRAM label. The Group specified here will be matched against the value specified in Rx-Inventory. In the example above, we set _MFRAM=ABC for the frame(s), so that is the group of frames to set the VCA value for:

Please ensure the Device Interface Params for the device have the appropriate OMA Label Table ID specified in the Other tab of Device Interface Params:

 

If found, the value of VCA Label Setting will be returned by the device interface. For the following example job:

The request from the device shows:

The value ABCDEF comes from the VCA label table entry in table MEI for tag _MFRAM, since the job is P material and the frame used on the job has an _MFRAM value (or group) of “ABC”.

In this way, different groups of safety frames can have different _MFRAM values in Rx-Inventory, and these can be translated to different _MFRAM values for device(s) according to any combination of material, style, tint, treatment, and addon for orders.
