This allows users to conveniently control devices such as lights or curtains by tapping on the indoor monitor or the SmartPlus App. > [!NOTE] > Note > > The following models with specific firmware versions or higher support configuring external relays on the web interface: > > - S567: 567.30.12.802; > - S562: 562.30.14.204; > - S562-2: 5622.30.15.18; > - S563: 563.30.12.902; > - S565: 565.30.10.210; > - X933: 933.30.13.702; > - X937: 937.30.13.122; > - C316: 316.30.13.102; > - C319: 119.30.12.902; > - IT88: 88.30.12.904. > > Currently, only the following models with specific versions or higher support configuring [akubela RCU inputs](/v1/docs/configure-external-relays-connected-to-indoor-monitors#configure-external-relays) on the web interface. > > - S567: 567.30.114.203; > - S565: 565.30.10.324; > - S562: 562.30.14.408; > - S563: 563.30.14.306; > - X937: 937.30.14.306; > - X933: 933.30.14.403; > - C319: 119.30.14.503; > - C316: 316.30.14.607; > - IT88: 88.30.14.603. ## MK485 ### Wiring Diagram The MK485 should be connected to Akuvox indoor monitors via RS485 ports. It has 8 relay output ports that can connect up to 8 home automation devices. - Connect devices to the C and B ports for a normally open. - Connect devices to the C and A ports for a normally closed. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/图片-IJ3E30H6.png) ### Configuration on the Web Interface After correct wiring, you need to configure external relays on the indoor monitor’s web interface. 1. Use the device IP to log in to its web interface with the username and password. The initials are both **admin**. 2. Go to the **Device > External Relay** interface. 3. Select **Akuvox-MK485-G2R-8J8C V3.0** as the External Relay Type. 4. Select the **External Relay Mode** for the indoor monitor to control the external relays. 5. Enable the desired key and select the relay function. 6. Set the **Hold Delay** time that decides how long the relay is activated. **Never** means it keeps activated once it is triggered. 7. Customize the **Display Name**. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-EC2R6PPW.png) 1.

Go to the **Device > Relay Setting > Home/More Page Display** interface. 2. Select **External Relay** to be displayed in the desired area. You can rename the button in the Label field. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-8DYXWUQ8.png) 1. Click Submit. ## RSAC-C1-R8 ### Changelog With specific versions or higher, indoor monitors support using RSAC-C1-R8 inputs as configurable security zones with arm/disarm control and alarm triggering. > [!NOTE] > Supported Model and Minimum Version > > - S562: 562.30.16.126 > - S565: 565.30.15.524 ### Wiring Diagram The RSAC-C1-R8 should be connected to Akuvox indoor monitors via RS485 ports. It has 8 relays and 8 outputs that can be connected to smart home devices and controlled by the indoor monitor. | Zone | Port | Wiring Instructions | | --- | --- | --- | | Relay | K1 ~ K8 | Connect to the load devices. | | L | Connect to a 100- 250VAC line wire. | | Output | OT1 ~ OT8 | Connect to the negative wire of the output devices. | | 12V | Connect to the positive wire of the output devices | | Input | IN1 ~ IT8 | Connect to one wire of the input devices. **NOTE**: On the indoor monitor’s web interface, inputs can be linked to outputs/relays. When inputs receive a signal, the corresponding outputs/relays can be triggered. | | COM | Connect to the other wire of the input devices. | ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-ZSY0JFCT(1).png) After wiring, toggle on the DIP switch 1. Otherwise, the indoor monitor will not detect the device. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/Switch Actuator DIP Switch2.jpg) ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/Switch Actuator DIP Switch1.jpg) ### Configuration on the Web Interface After correct wiring, you need to configure external relays on the indoor monitor’s web interface. 1. Use the device IP to log into its web interface with the username and password. The initials are both **admin**. 2. Go to the **Device > External Relay** interface. 3. Select **RSAC-C1-R8** as the External Relay Type. The indoor monitor can be connected to 3 RCUs. **Device 1** is enabled by default. To use more, enable Devices 2 and 3 at the bottom of the web interface. 4. Enter the device address determined by the DIP switch. > [!NOTE] > Note > > The address mapping is as follows: > > | Switch Number | Address | > | --- | --- | > | 1 | 1 | > | 2 | 2 | > | 3 | 4 | > | 4 | 8 | > | 5 | 16 | > | 6 | 32 | > > > > **Example**: > > - When you toggle on Switch No. 1, enter 1 in the device address box. > - When you toggle on Switches No. 1, 2, and 3, add their values (1 + 2 + 4) and enter 7 as the device address. 1. Enable **RSAC-C1-R8 Inputs as Arming** if needed. When enabled, the inputs can function as security zones and support arm/disarm operations. Once a connected sensor is triggered while the zone is armed, the system generates an alarm event in the same way as the indoor monitor's built-in security zones. 2. Enable the desired keys and select the relay function. 3. Set the **Hold Delay** time that decides how long the relay is activated. **Never** means it keeps activated once it is triggered. 4. Customize the **Display Name**. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-EN00JRDW.png) 1. Enable the desired digital outputs and select the function. 2. Enable the desired digital inputs and select the trigger mode and linked relay/output. When inputs receive a signal, the corresponding outputs/relays can be triggered. 3. Customize the **Display Name**. 4. Enable/disable **Show Pop-up**. This decides whether to display a prompt on the indoor monitor when the input is triggered. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-PWHSOSD6.png) 1.

Name the unit and select its function. Further configure the settings. Take **Light** as an example. 1. Choose the output interfaces that are connected to the light for controlling its on/off. 2. Set the **Hold Delay** time that decides how long the unit is activated. **Never** means it keeps activated once it is triggered. 3. If needed, you can add input(s). The input is linked to the relay/output. When inputs receive a signal, the corresponding outputs/relays can be triggered. It can be a button or a sensor connected to the input. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/Screenshot 2025-06-23 142243(1).png) 1.
