Spec Sheet

4 Port 4K DVI KVM Switch in mission-critical applications
With DL-MUX KVM switches, you can operate 4 computers over 1 user console.

The DL-MUX switches the following signals:

  • Keyboard/mouse
  • Dual-link DVI and VGA
  • Audio
  • USB 2.0

The device is available in variants transmitting 1, 2, 3, or 4 video channels.

With its network connection, the web interface and DLM monitoring, the DL-MUX4 provides numerous features for mission-critical applications.

DLM monitoring function

The integrated DLM-Monitoring auto-transmits device status messages to syslog servers or sends them as SNMP. Manual monitoring is carried out over the web interface.

The DL-MUX monitoring function queries the following values:

  • Power supplies (on/off)
  • Temperature limit (above/below average)
  • Connection cable (interrupted/uninterrupted)
  • Computer (on/off)
  • DVI video input (available/not available)
  • Access settings (set preferences)

The DLM-Monitoring enables proactive monitoring instead of reactive maintenance.

Easier access with SNMP tool Zabbix

For customers who are not yet using extensive SNMP tools, G&D offer a simple way to use the functions included in the devices. Templates for the open source tool Zabbix are provided here. The program lets users monitor SNMP-capable devices in a network and, among other things, issues warning notifications about critical device states, which have been received via SNMP trap.
