Installation and Connections
V680S-HMD66-ETN
Install the Reader/Writer with four M4 screws. Use both spring washers and flat washers.
When you install the Reader/Writer, prepare the metal plate shown in the following figure.
When the metal plates size is larger than the below illustration, communication range will change.
Although it is possible to use SUS, aluminum or brass in addition to steel as the metal plate, communications range is
influenced by the material. Do not use resin as the metal plate.
The recommended tightening torque for M4 screws is 1.2 N·m.
Refer to
Reader/Writer Installation Precautions
for information of surrounding metal and Mutual
