INTRODUCTION
 Power and Ground Cables
• Use an appropriate ground. An insufficient ground can affect this product operation or result in dam-
age to this product.
 About the communication range and time
• Do the communication test with Transponder in the installation environment because the metal,
noise and ambient temperature around CIDRW head damage to the communication range and time.
• Install CIDRW head and ID tag in the appropriate distance because the communication range can
change by the difference of ID tag specifications.
 Installation
• 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 134.
• Do not install the Controller near any equipment that generates a large amount of heat (such as
heaters, transformers, and large-capacity resistors).
• Tighten the mounting screws on the Controller securely (recommended tighten torque: 1.2 N·m).

Screw Locking Adhesive
• Screw lock can cause plastic parts to deteriorate or crack. Do not use it on plastic screws or plastic
washers.
 Host Communications
• Always confirm that the Controller has been started before attempting to communicate with it from
the host.
When the Controller is being started, unstable signals may be output from the host interface. When
starting operation, clear the reception buffers in the host or take other suitable countermeasures.
 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.
 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.
