4. Perform a network scan in the KD-App/KDMS™ and select the unit.

5. To control, first select the display / output, then the source / input

6. Use the buttons at the bottom of the screen to choose HDMI + External Audio (6a), HDMI AV only (6b) or External Audio only (6c) routing.
   

7. To enter KDMS Pro end-user mode, key CTRL + ALT + N after selecting the unit in the devices tree.

Option 3: Control via web UI

Access KD-MS8x8G-2’s web UI from any phone, tablet, or PC. The web UI shows the input, output, and unit name, for a user-friendly experience.

1. 

2. Connect and Configure your KD-MS8x8G-2 as described in the Connect & Configure sections

3. Ensure the PC, phone, or tablet are on the network with KD-MS8x8G-2

4. Enter IP Address of KD-MS8x8G-2 unit into the web browser search bar

5. Enter password. Default password is “admin”

7. Use the Web UI Settings Menu (6a) to update names of the device, inputs, and outputs (6b), as well as updating the network settings and Admin password (6c).
   

Option 8: Control via professional control system

KD-MS8x8G-2 allows control over serial interface for bi-directional communication.

• For RS-232 control use pins 8, 5, and 6 of the Unit Control port. Baud Rate is 57,600
  

• For TCP/IP control the default static IP address is 192.168.1.239, with port 23.

• KD-MS8x8G-2 supports KD’s standard matrixing protocol, so if you have controlled a KD matrix with a third-party control system before, you will likely have success with the same driver/module.
  a. Switching HDMI AV + External Audio together
  i. SPO xx Soy xx = output (01-08), by = input (01-08)
  b. Switching HDMI AV Only
  i. SPO xx Say xx = output (01-08), by = input (01-08)
  c. Switching External Audio only
  i. SPO xx Say xx = output (01-08), by = input (01-08)

• A carriage return is required at the end of each string. See the TCP/IP and RS-232 Commands section for full command set and protocol.

 Test for proper operation of the unit and cables in your system before permanently securing the unit for final installation. Ensure that you leave enough ventilation space to provide sufficient airflow and cooling
