1.Introduction
is a new generation of embedded CDT-Wifi products module.
CDT-Wifi is based on CDT interface, accord with Wifi wireless network standard embedded
module, the built-in wireless network protocol IEEE802.11 protocol stack, and TCP/IP protocol
stack, save electricity intelligent control procedures
Can realize, the user serial data to the wireless network conversion between.
Through the CDT-Wifi module, the traditional serial equipment also can easily access wireless
network.
is in the first two generations of products based on top, and carries on the
comprehensive hardware and software upgrades, function more powerful, use more simple, lower
power consumption In the original foundation above the intelligent current control program
upgrade, than the former two generationproduct province electricity above 40%.
In temperature compensation, the application of the latest software automatic control technology,
automatic temperature adjustment, and will not affect the data transmission, it solves the
traditional product, because the temperature too high, cause data loss, frequent fall nets, etc

Usage Guidelines for FCC Compliance
Antenna Selection
In order to maintain compliance with FCC regulations, an antenna with no more than 2dBi gain
must be used. This module has been tested with the following antennas:
nix Part Number Antenna Type Antenna Gain DTS
Part Number Antenna Type Antenna Gain
ANT-2400-01A External antenna 2.0 dBi
Mode LP Mode
The module when used in DTS mode, may be used with the above antennas and maintain the
requirements of the FCC grant.
Module Modification
The module must not be physically altered in any way. If any connections are made to the
module that bypass the module pins, socket, or antenna connector, the FCC modular
certification cannot be inherited.
End Product Labeling Requirements
Pursuant to FCC public notice DA 00-1407, the end product must be labeled on its exterior
with the following verbiage:
“Contains FCC ID: ROWCDT-XX5370”
Additional FCC Testing Requirements
While the module’s FCC certification can be inherited (presuming the guidelines are met),
additional testing will be required to achieve full FCC compliance for your end-product. The
integrator is required to perform unintentional radiator testing on the final product per FCC
sections 15.107 and 15.109.
Additional, product-specific testing might be required. Please contact the FCC regarding
regulatory requirements for your application.
RF exposure compliance
The Module should be install above separation distance 20 cm from human.
It should add SAR testing when it not satisfy.

Certification. This certification may be install in an end-user product, negating
the need for FCC part 15 intentional radiator testing on this module, provided that
the following are met:
1. The module must not be modified in any way. Coupling of external circuitry
must not bypass the provided connectors.
2. End product must be externally labeled with “Contains FCC ID:
ROWCDT-XX5370”
3. The end product’s user’s manual must contain an FCC statement equivalent
to that listed in Customer FCC Warning Requirements of this manual.
6. The integrator must not provide any information to the end-user on how to
install or remove the module from the end-product.
The integrator is required to perform unintentional radiator testing on the final
product per FCC sections 15.107 and 15.109.
Customer FCC Warning Requirements
The end-product user’s manual must contain the following or equivalent verbiage.
Notices of Limitation
Product Testing
The integrator must still show that their product complies with FCC regulations applicable to
their product. The integrator is not required to perform transmitter testing on the
DTS module, provided the guidelines in this document are met.
FCC NOTICE (Containing FCC ID: ROWCDT-XX5370)
The RF module (FCC ID: ROWCDT-XX5370) contained within this device
complies with the rules set forth in Part 15 by the Federal Communications
Commission.
Operation is subject to the following conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference
that may cause undesired operation.
4. The module must not be modified in any way. Coupling of external circuitry
must not bypass the provided connectors.
Any changes or modifications could void the user’s authority to operate the
equipment.
