Recover a Fixed/Static Dante IP Address
If you’ve accidentally assigned a fixed IP address to a Dante interface and can no longer access the device, this manual explains how to reset the Dante configuration and restore connectivity:
Revert to Automatic Control IP Address
If you have installed KOS 5.7+ on your KLANG processor, you can revert to DHCP / automatic IP address by pressing the Reset Button twice. For more options see below:
This guide explains what the LED colors mean on a KLANG processor without a display. It helps users understand the network status, connection state, and audio clock validity — even before connecting a KLANG:app.
LED States
Once connected, the LED becomes solid purple, or it blinks purple/red when the audio sync is not valid.
| Diagnostic Mode | Blinking LED State | Meaning | Notes |
|---|---|---|
| Half-Dim Purple | IP assigned via DHCP | DHCP server provided a valid IP |
| Blue | Using link-local Auto-IPs: 169.254.x.x/16 | No DHCP, auto-assigned fallback IP |
| Orange | Using a user defined Fixed IP | Manual IP set via KLANG:app or console, other than 192.168.1.200 |
| White | Using Default KOS IP: 192.168.1.200/16 | Default fixed IP that works well with default DiGiCo console IP addresses |
| Pulsing Purple | Waiting for :app/:kontroller/console to connect… | Will overlay one of the above colors as base status |
Once a KLANG:app or console connects, the LED indicates connection and audio clock status:
| Connected LED State | Meaning |
|---|---|
| Solid Purple | ✅ Connected to at least one :app, :kontroller or console |
| Blinking Purple/Red | ⚠️ Audio clock is invalid (e.g., no sync) |
Basic Configuration with Reset Button Presses
Reset Button on KLANG processors allows to trigger often used configuration features with minimal GUI.
| Button Pattern | Action | Notes |
|---|---|---|
| Single Short Press | Write Logs & Backup to USB | Flash green (short) to confirm |
| Long Press (>3s) | Reboot | Flash red → solid red → reboot |
| Double Short Press | Revert to DHCP | Flash purple 2x → confirm with dim purple |
| Triple Short Press | Set default fixed KOS IP 192.168.1.200 | Flash white 3x → confirm with solid white |
| Five Short Presses | Enter Factory Reset mode | LED blinks blue/purple rapidly |
| Then Long Press | Confirm Factory Reset + Reboot | Flash red rapidly before reboot |
The Factory Reset, will delete all settings and therefore also the Split Control IP address and the VLAN settings.
