Page 12 of 18 5.5 PWRKEY(Pin9) The power key function is turn on/off the power source of module. The default setting is low for the module in operation mode 5.6 USB(Pin5,11,12) The USB interface is compliant with Version 2.0 of the USB standard for high speed operation. *Download mode: Short KCOL0 and KROW1 together for USB upgrade/download image. 5.7 Antenna Port(Pin19) In this module, we have one antenna port for signal transfer. To reduce the RF trace loss, the antenna port in the module had better be as close as possible to the antenna pad in the PCB. For maximum transmitter power and receiver sensitivity, a 50Ω transmission line is suggested to connect the antenna pad and the antenna port of the module. In
Page 13 of 18 addition, the RF signal will be impacted by high data rate. We strongly suggest USIM signal trace to be short as possible and as far away as possible from the RF trace and power line. To prevent cross coupling, signal traces on your PCB must not be routed through the module backside. Antenna Pad The antenna pad in your PCB should be 3~5mm wide and there must not be any other traces and ground under the pad. If needed, the matching network can be added between the antenna pad and antenna port. The recommended circuit is shown as below: 5.8 UART interface This module can support baud rate from 9600 to 9121600.

This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. IMPORTANT NOTE: This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC compliance requirement of the end product, which integrates this module. 20cm minimum distance has to be able to be maintained between the antenna and the users for the host this module is integrated into. Under such configuration, the FCC radiation exposure limits set forth for an population/uncontrolled environment can be satisfied. Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this equipment. USERS MANUAL OF THE END PRODUCT: In the users manual of the end product, the end user has to be informed to keep at least 20cm separation with the antenna while this end product is installed and operated. The end user has to be informed that the FCC radio-frequency exposure guidelines for an uncontrolled environment can be satisfied. The end user has to also be informed that any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this equipment. If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be available in the users manual: This device complies with Part 15 of 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 undesired operation. LABEL OF THE END PRODUCT: The final end product must be labeled in a visible area with the following " Contains TX FCC ID: N69-715100". If the size of the end product is larger than 8x10cm, then the following FCC part 15.19 statement has to also be available on the label: This device complies with Part 15 of 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 undesired operation. 8 Construction and setup The Module test is comprised of two basic steps. The first is to put the DUT into module test jig and the second is to connect the PC terminal emulator and start the measurement tool:
