 How to Connect The FC-301/D to the D-Star Board with Connection cable

Here is the connection diagram showing the connection between the Moencomm GMSK modem and the FC-301D radio.

dwmzone-FC-301DU UHF-VHF 1-5W-High -power -Multi-channel- Narrowband-Data and voice-radio Transceiver-Module

Connection cable plugs required:

FC-301D: Male D-sub 9 pin
Star*Board: Female D-sub 9 pin

FC-301D pin description:
1 = Audio In
2 = Audio Out
3 = PTT
4 = GND
5 = +12V
not used for Moencomm setup:
6 = CD/SQL
7 = RSSI
8 = Programming enable (link to GND)
9 = Speaker Output (8 Ohm / 0.5W)

RFduino Board & LoRa module as DK board User guide

     RFduino Board original design for all of the Wireless modules can share with same Library and can run a Wireless communication code with the RFduino Board.This User guide will show you how to use the RFduino Board to delevelop the RFM92W,RFM95W,RFM96W,RFM98W  LoRa module etcs.

    RFduino Board which also name HopeDuino But we used to call it as RFduino board.If there are any questions please contact us sales@dwmzone.com. We will give more details about the name.

If you are  the firt time use the   RFduino Board please visit the  RFduino Board User Manule.

  1. Prepare Hardware and software:

2. Operation

 1.) Set two RFM9X LoRa module to The RFduino Board .

rfduino-board

2.) Connect the RFduino Board to the PC by USB cable.

   3.) Opens the Arduino IDE interface, click on the [file] – > [Examples] -> [HopeRFLib] ->[lora_Tx], below operation;

   4.) Opens the Arduino IDE interface, click on the [file] – > [example] -> [HopeRFLib] -> [lora_Rx], the following figure.

5.) Compile and download the Software.

Since there are two USB cable connect to one PC and one Aduino ID there are onething need to be carefull that’s the Serial port,each of time you compile and download the LoRa_Tx and LoRa_Rx You have to choice the correct Serial Port.You can see the serial port on the right down corner which shows as below:

Dwmzone-LoRa-module-RFduino-board-serial-poart

 6.) Serial Port Monitor the TX and RX communication.

After Compile and download the Software the TX will start the wireless transmission periodically and you can set the Rx serial port and check the received data package by click the “Serial Mornitor”.

Dwmzone-LoRa-module-RFduino-board-serial-poart-monitor

It will open a new windows and display the data received.shows as below:

Note: You can check the UART Library  which content the function for UART communiction here is the Route: HoepRF-HSP->libraries->HopeRFLib -> HopeDuino_UART.
