**Main Procedure**

**Connect to ATC-863 using RF module software.**

 

1. Go to the device manager on your PC and check what port is assigned.

![](https://support.gridconnect.com/hs-fs/hubfs/kb-migration/gridconnect/28517278311699_28517278311699.jpeg?height=120&name=28517278311699_28517278311699.jpeg)

1. Open the “**COM Option**” and click the “**COM Set**” button on the software toolbar.
2. Choose “**COM Port**” from the drop-down menu and click the “**Open**” button.

Note: In this menu, you will select the COM Port assigned on the device manager (COM7 in this example)

1. Click “**Search**” on the Toolbar. The software will “begin the Search.” If a signal radio is detected, the Status bar will indicate “successful search” and display device information. If not, the system will indicate “can’t search”. Thus, you should follow the next troubleshooting:

1. Check the power or data line, 
2. The interface is RS232 or has been changed to RS232.

Once the previous troubleshooting has been done, click the “**Search**” button to begin the search again.

Note: We suggest “Search Radio” before setting the RF module/radio parameters. Once the Search is successful, don’t change the properties of the COM again.

**Getting ATC’s Values**

1. To get the ATC-863's default settings, click on the **Read** button. This will show the device’s parameters for setting up any radio device you need to talk to.

1. The device parameters can also be set according to any particular needs by setting them individually.

1. **Channel and frequency**

2. **RF Baud Rate**

**Connecting the second ATC-863-S1 to the RF Module Software**

1. Connect the second ATC-863 to a USB port, then **go to** the device manager and check the “COM” available.

1. Open a second RF module Software.
2. Click on the “**COM option”** then click on “**COM Set”**
3. On the next window for “*COM Port”.* Select the COM Port available on the device manager (COM5 in this case), then click “**Open”**

![](https://support.gridconnect.com/hubfs/kb-migration/gridconnect/28517278330131_28517278330131.jpeg)

1. Click **Search** to get the information from the second ATC-863 (COM5).

![](https://support.gridconnect.com/hubfs/kb-migration/gridconnect/28517278338835_28517278338835.jpeg)

**Match the first ATC-863 (COM7) parameters**

**Manually Set: **

1. **Channel and Frequency** to Channel 4 with a frequency of 433.916MHZ (the frequency is populated by default when you choose the channel). Once you select the Channel, ***it is essential to*** *click on the Write(2) button* ***to save the changes.***
2. **RF Baud Rate** to 19200, then *click on the Write(2) button *
3. **COM parameters** to 

- Baud Rate: 9600
- Verify: NONE. Then *click on the Write(2) button*

**![](https://support.gridconnect.com/hubfs/kb-migration/gridconnect/28517278340499_28517278340499.jpeg)**

Note: Here, you can set the ATC-863 to match your device parameters or set your device to match the ATC-863 default settings. These parameters have to be the same for both devices to establish a connection.

 

**Steps to make the radio test **

1. **Set the Main RX:**

1. Choose the primary receiving side by going to the “**Transmit Both Sides**” tab of the software, 
2. Select “**Main RX**”, and click the “**receive**” button to enable the receiving status. 

In the “**TX option**,” we can choose “*TX after Return*” or “*Timing TX*.” The **“TX after Return”** means it can transmit the data after receiving it from the main transmitting side, while the **“Timing TX”** means transmitting the data at a set time.

Note: the TX Option is set to “TX after Return” by default.

1. **Set Main TX**

To send Data to the second ATC-863 (COM5)

- On the first ATC-863 (COM7), Make sure you move to the “**Transmit Both Sides**” tab.
- Then “**Main TX**”, and input the content in the Textbox, click “**Send**”
