The V680-D2KF67M is designed to be mounted directly to metal. The V680-D2KF67 and V680-
D2KF67M markings are shown in the following diagrams.
The side with the markings is the communications surface. Mount the Tag with this side facing the Antenna.
The ID READ command is used to write the ID code to the ID Tag's memory, and therefore will be affected by the
ambient temperature. Be careful when using the ID Tag in environments with high ambient temperatures.
