DVI

All models handle dual link DVI and VGA — mixed, at inputs and outputs. A computer with a VGA output and one with a DVI output can share the same switch, and on the monitor side you are not tied to one signal type either. Converters or separate workplaces become unnecessary.

• DVIMUX-DL — four computers, no network connection. The base equipment for workplaces without particular monitoring requirements.
• MUX-NT — two or four computers, plus a network port with web interface and monitoring, and redundant power. The DCS variant also belongs to this range.

The DCS variant (Dry Contacts Switching) switches via dry contacts. This allows switchover to be triggered from a higher-level control system — plant or building control, for instance — without any action at the workplace. Within the switch portfolio, this switching method is available in the DVI range only.

The multi-channel variants switch two, three or four monitors per computer together. This is available in both ranges.

DVI carries no audio within the video signal, so the switches route sound over a separate analogue channel. Embedded audio is not available with DVI — if sound is to travel digitally within the video signal, the DisplayPort switches are the way to go.

• Can I run DVI and VGA computers on the same switch?
  Yes. Mixed operation applies to inputs and outputs, in both ranges.
• Do I need a special version for seamless switching?
  No. All DVI switches change over without a visible interruption. InstantSwitching is a function required with DisplayPort, because that standard behaves differently when switching.
• How many computers can I connect?
  Four with DVIMUX-DL, two or four with MUX-NT.
• How does audio reach the workplace?
  Over a separate analogue audio channel of the switch.
• Which range do I need for monitoring?
  MUX-NT. The DVIMUX-DL range has no network port.
