Android ET55 missing DataWedge

Recently my company got in an Android ET55 with the expansion back scanner for testing. The tablet did not however have the DataWedge app pre-installed, causing scanning in our productivity app to fail. Our software keys on a specific scan prefix and suffix to facilitate scanner processing. Can the DataWedge apk be downloaded or is there a specific device configuration that needs to be purchased that includes the DataWedge app pre-installed? The model # of our device is CHG-ET5X-CBL, part # CHG-ET5X-CBL1-01, serial # 018701167080576B. Previously we were deploying our app on the ET1 tablet which had the DataWedge app pre-installed.
