Reader/Writer Installation Precautions
V680S-HMD63-ETN
Influence of Surrounding Metal on Reader/Writer
The Reader/Writer can be surface-mounted or it can be embedded in metal to protect it from collisions.
If you embed the Reader/Writer in metal, separate it at least 80 mm from any metallic surface to
prevent malfunctions. If the distance between surrounding metal and the Reader Writer is less than 80
mm, the Reader Writer communications distance will be greatly reduced.
Do not allow the height of the metal to exceed the height of the Reader/Writer.
Mutual Interference of Reader/Writers
To prevent malfunctioning due to mutual interference when using more than one Reader/Writer, leave
sufficient space between them as given in the following table.
If the distance between the Reader/Writers is too short, the read/write distances will be reduced.
