(U.FL Connector) The maximum power supplied to each port is 30dBm. Note : Only one RF Port can be used at a time, and default setting is ANT0. Please refer to the command document for the antenna selection method. Date Rev Page 2020-12-09 06 5 B. Antenna Requirements KCTM-2000 is affected by the characteristics of the antenna. In the frequency band of the antenna, it is recommended to use an impedance of 50 ohm and VSWR value (less than 1.25). WARNING : If you output RF power while the antenna port is open, the module may be damaged. C. HOST Interfaces The connector pins consists of power pins, serial communication pins and power on/off signal pin. It has two connectors(YEONHO 12505WR-10, HIROSE DF40C-40P-04951) that connect to the host.

Environmental Specification KCTM-2000 can be connected to the Host in two ways. One is to connect using the Board to Board Connector, and the other is to use a 10pin Harness Cable. Date Rev Page 2020-12-09 06 10 In both cases, it is recommended to fix the module to the main board. When the KCTM-2000 is operated at Max Power (30dBm), a lot of heat is generated, it is possible to mitigate the temperature rise during operation of the module by spreading the heat of the module to the main board. When mounting the module on the main board, open the PSR in the module area so that the main board and the ground of the module are sufficiently contacted. It is recommended to shield the module because harmonic generated from the Host Processor may flow into the antenna of the KCTM-2000 and cause performance degradation. Note: 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 does 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. This device complies with part 15 of the FCC Rules. Operation is subject 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 Caution : Any changes or modifications in construction of this device which are not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. undesired operation. End Product Labeling The module is labeled with its own FCC. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label Date Rev Page 2020-12-09 06 11 referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following:
Contains FCC ID: 2ARHH-KCTM-2000 OEM Responsibilities to comply with FCC condition:
The module has been certified for integration into products only by OEM integrators under the following
- The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained between the radiator (antenna) and all persons at all times.
- The module is limited to installation in mobile or fixed applications.
- The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
- Separate approval will be required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations other than supplied antennas. requirements, etc.). As long as the two condition above is met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral In the event that these conditions cannot be met, then the FCC authorizations are no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product including this module and obtaining separate FCC authorizations.
- This device is intended only for OEM integrators
- For OEM integration only device cannot be sold to general public.
- Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module.
