Applicable Standards

FCC (USA) Part 15 subpart B and C

This device complies with part 15 of the FCC Rules. Operation is subjected to the following

two conditions:

(1) This device may not cause harmful interference, and (2) this device must accept any

interference received, including interference that may cause undesired operation.

FCC ID : E4E6CYAID7000100

FCC NOTICE

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not installed and

used in accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a particular

installation. If this equipment dose cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and on, the user is encouraged to try to

correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

-Consult the dealer or an experienced radio / TV technician for help.

FCC WARNING

Changes or modifications not expressly approved by the party responsible for compliance could

void the user’s authority to operate the equipment.

Properly shielded an grounded cables and connectors must be used for connection to host

computer and / or peripherals in order to meet FCC emission limits.

AC adapter with ferrite core must be used for RF interference suppression.

Precautions of Use

This device uses a frequency of 125 kHz to communicate with a tag. Some transceivers,

motors, monitor units, and power supply (power IC) emit noise that adversely affects this

communication with the tag. If this product is to be used in an environment close to such

devices, please check the effects from these devices prior to use.

To minimise the effect of noise, please ground any metal object surrounding this device.

3. Operations of the R/W Module

3.1 Outline of operations

The R/W Module receives commands from the User board, executes read / write

processes on the Tag, and returns a response of the results of the process to the

User board. The status of the R/W Module operations will be reflected on the Output

/ LED.

3.2 Oscillation Control

The R/W Module supplies power to the Tag by oscillating the antenna, and thus

conducts communication with the Tag. The Module may be set on either the

“Oscillate Mode”“Stop Mode”depending on whether the Module should oscillate

while not in communication with the Tag. The “Stop Mode”conserves dissipation

power, and enables the R/W Module antenna to be installed close to the Tag to

conduct communications on a time sharing basis. The “Oscillate Mode”allows the

Module to constantly supply power to the Tag for FIFO processing.

3.3 Input STOP

When a STOP signal is input to the R/W Module, receiving and processing of

commands and command processing will stop and then, after the STOP signal is

deactivated, the Module will be on stand by for new commands. When the STOP

signal is input, oscillation will stop regardless of the setting of the oscillation control

mode.

If a STOP signal is input more than 50 msec prior to shut down, writing of unstable

data to the Tag may be prevented. However, if writing of the command in process

requires more than one page, not all pages may be completely rewritten.

3.4 Memory Management on Tag

The Tags used to conduct communication with the R/W Module may be one of the

following two types depending on memory capacity: 128 bytes (user area 112 bytes)

or 256 bytes (user area 240 bytes). The memory area recognizes every 8 bytes as

one page, distinguished by such addresses as 00h ~ 07h, 08h ~ 0Fh, and so on.
