■ About mounting
• This product communicates with ID Tags using the 134 kHZ frequency band. Some transceivers,
motors, monitoring equipment, and power supplies (power supply ICs) generate electrical waves
(noise) that interfere with communications with ID Tags, If you are using the product in the vicinity of
any of these devices, check the effect on communications in advance.
• In order to minimize the effects of noise, ground nearby metal bodies with a grounding resistance not
exceeding 100 ohms.
• When mounting CIDRW Heads, tighten the screws tightly.(Recommended 0.6N·m)
• When multiple CIDRW Heads are mounted next to each other, communications performance could
be impaired by mutual interference. Read and follow the information in this manual on mutual inter-
ference when installing multiple heads.
Refer to page 86.
■ Screw Locking Adhesive
• Screw locking adhesive (screw lock) may cause deterioration and cracking of resin parts; do not use
it for screws in resin parts or anywhere where resin washers are used.
■ Startup Precaution
Never turn OFF the power supply while the CIDRW Controller is starting, including when power is
turned ON, when the mode is changed, or when the CIDRW Controller is being reset. Doing so may
damage the CIDRW Controller.
■ Application Precaution
Never turn OFF the power supply while setting the IP address, subnet mask, or Web password. Doing
so may damage the Amplifier Unit.
■ About Transponder and RF module made by Texas Instruments Co.
(1) We can't warrant the specifications of the communication with Transponder and RF module.
(2) When the RF module is at fault, we can't analyze the RF module.
■ The characteristics of the V640-HAM11(-L)-ETN / V640-HAM11(-L)-ETN-V2
It is a circuit, designed to communicate characteristics match, but because it is intended to carry out
the communication with RF module and the transponder, can not be guaranteed.
