---

1. Prerequisites

Hardware Requirements

Supported Matrix Models:

• OREI BK-808 8x8 HDMI Matrix Switcher (tested and verified)

Network Setup:

• Matrix connected to local network (Ethernet)
• PC on same network as matrix
• Matrix with static or known DHCP IP address

Software Requirements

• TMRemote 2.73 or later
• Windows 10 / 11
• .NET Framework 4.8 or higher

2. Initial Matrix Configuration

Step 1: Physical Setup

1. Connect Matrix to Network

   Matrix [LAN Port] --- Ethernet Cable --- Router/Switch

2. Power On Matrix - Front panel LED should illuminate. Wait 30 seconds for boot.
3. Find Matrix IP Address

Method A: Matrix Display (if available)

• Press MENU button on matrix
• Navigate to Network Settings
• Note IP address shown

Method B: Router Admin Page

• Log into router (usually 192.168.1.1)
• Find "Connected Devices" or "DHCP Clients"
• Look for device named "OREI" or "Matrix"

Method C: Default IP

OREI BK-808 default IP: 192.168.1.100

Step 2: Verify Matrix Accessibility

Ping Test:

ping 192.168.1.100

Expected: Reply from 192.168.1.100: bytes=32 time<1ms TTL=64

Web Interface Test:

• Open browser
• Navigate to: http://192.168.1.100
• Should see OREI BK-808 matrix web interface

3. Connecting to Matrix

First-Time Connection

1. Launch TMRemote - Right-click system tray icon
2. Navigate to: HDMI Matrix - Connect Matrix - Network (IP)...
3. Enter IP Address - Dialog will show default: 192.168.1.100
4. Verify Connection - Balloon notification shows connection status

Troubleshooting Connection

Problem: "Failed to connect to matrix"

• Solution 1: Verify Matrix Power - ping 192.168.1.100
• Solution 2: Check Firewall settings
• Solution 3: Verify same network subnet
• Solution 4: Reset Matrix Network Settings (hold RESET 10 seconds)

4. Creating Matrix Profiles

Method 1: Save Current Routing

1. Configure Matrix Routing via web interface or front panel
2. Right-click tray icon - HDMI Matrix - Save Matrix Profile...
3. Enter profile name and click OK

Profile saved to: %APPDATA%\MonitorSwitcher\Matrix\{ProfileName}.xml

Profile XML Structure

<?xml version="1.0"?>
<MatrixProfile>
  <ProfileName>Gaming Setup</ProfileName>
  <Description>Saved on 2025-11-26</Description>
  <PresetIndex>0</PresetIndex>
  <Routes>
    <int>3</int>  <!-- Output 1 <- Input 3 -->
    <int>3</int>  <!-- Output 2 <- Input 3 -->
    <int>1</int>  <!-- Output 3 <- Input 1 -->
    <int>5</int>  <!-- Output 4 <- Input 5 -->
    <int>1</int>
    <int>2</int>
    <int>3</int>
    <int>4</int>
  </Routes>
  <ExternalAudioInput>0</ExternalAudioInput>
</MatrixProfile>

Method 2: Use Device Presets

Use the matrix's built-in presets (1-8) for faster switching:

<MatrixProfile>
  <ProfileName>Gaming (Preset 3)</ProfileName>
  <PresetIndex>3</PresetIndex>
  <!-- Routes ignored when PresetIndex > 0 -->
</MatrixProfile>

5. Loading Matrix Profiles

Manual Loading

1. Right-click tray icon - HDMI Matrix - Load Matrix Profile...
2. Select profile from list
3. Routing applied to matrix

---

6. Profile Linking

Link Configuration

Create link file at: %APPDATA%\MonitorSwitcher\MatrixLinks\{MonitorProfile}_Link.xml

<?xml version="1.0"?>
<MonitorMatrixProfile>
  <MonitorProfileName>Gaming</MonitorProfileName>
  <MatrixProfileName>Gaming Matrix</MatrixProfileName>
  <AutoApplyMatrix>true</AutoApplyMatrix>
  <PowerOnMatrix>false</PowerOnMatrix>
  <PowerOnDelayMs>2000</PowerOnDelayMs>
</MonitorMatrixProfile>

Link Options

Option	Description
AutoApplyMatrix	true = Auto-load matrix profile when loading monitor profile
PowerOnMatrix	true = Send power ON command before applying routing
PowerOnDelayMs	Delay after power on before applying routing (ms)

---

7. Advanced Features

External Audio Routing

Route HDMI audio from a specific input to the matrix's SPDIF/optical output:

<ExternalAudioInput>3</ExternalAudioInput>

• 0 = External audio disabled
• 1-8 = Route audio from specified input

Power Control

<PowerOn>true</PowerOn>   <!-- Power ON -->
<PowerOn>false</PowerOn>  <!-- Power OFF (standby) -->

Routing Patterns

Mirroring (Same Input to Multiple Outputs):

<Routes>
  <int>1</int>  <!-- Out 1 <- In 1 -->
  <int>1</int>  <!-- Out 2 <- In 1 (mirror) -->
  <int>1</int>  <!-- Out 3 <- In 1 (mirror) -->
  <int>1</int>  <!-- Out 4 <- In 1 (mirror) -->
  ...
</Routes>

---

8. Troubleshooting

Profile Not Applying

1. Check Matrix Connection: ping 192.168.1.100
2. Test Manual Command via tray menu
3. Verify Profile File XML is valid
4. Check Link File has AutoApplyMatrix=true

Wrong Routing Applied

Remember: Array index = Output number, Value = Input number

<Routes>
  <int>3</int>  <!-- Position 0 = Output 1 <- Input 3 -->
  <int>1</int>  <!-- Position 1 = Output 2 <- Input 1 -->
</Routes>

Slow Switching

• Reduce PowerOnDelayMs
• Use Device Presets (single API call)
• Check network latency
