Vlan; Physical Air Gap - Crestron AM-200 Deployment Manual

networks and corporate networks separate while allowing the users to share a display
need not be challenging. As a standard network device, AirMedia solves this problem by
using standard networking practices. There are two recommended methods:
the VLAN-based method, and the physical air gap method.

VLAN

In this scenario, AirMedia devices are placed in their own VLAN. This VLAN is configured
to allow only incoming connections. Outbound traffic is not allowed. The guest and
corporate networks exist in separate VLANs. Since outbound connections are not
allowed, the guest VLAN cannot access the corporate VLAN through the AirMedia VLAN.

Physical Air Gap

If networks (for security reasons) require some type of physical separation, there are
two approaches when using current AirMedia devices:
With devices such as the AM-101 that have a single network interface, two

AirMedia devices can be used, one for corporate users and one for guest users.
To switch presentations in the HDMI interface domain, use an HDMI switch such

as the DMPS3-4K-250-C or DMPS3-4K-350-C. While extremely secure, this
approach requires more hardware.
