Date 2020-12-09 Rev 06 Page 5 Please refer to the command document for the antenna selection method. 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.

Date 2020-12-09 Rev 06 Page 7 D. Control Signal Specification KCTM-2000 communicates with the host through the TTL logic level UART Signal Port. For Standard DC12V RS232 Device, Level converter must be applied. Hardware Handshaking is not supported. Baud Rates Support : - 9600 - 19200 - 38400 - 115200 ( Default) - 230400 - 460800 - 921600 Note : Please refer to Command document to get information about how to change the Baud Rate. E.

Date 2020-12-09 Rev 06 Page 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.
