The DL-AR2 Digital Adapter Keychain was developed to support the rising proliferation of mobile devices used in presentation systems. Most presentation infrastructures only support one or two input formats, usually HDMI® for Digital and VGA for Analog. This product permits the presenter easy access to the appropriate adapter for connection to the HDMI® infrastructure. Laptops, tablets, smart phones, digital cameras, and net books all have varying connections to display their content. This simple and effective ring of adapters permits the owner of the infrastructure to support mobile device content and keep the adapters secure and in place for the next presenter. The full DL-AR2 unit includes the following adapters in the basic format: (1) DisplayPort male to HDMI female, (1) Mini-DisplayPort male to HDMI female, (1) Mini-HDMI “C” male to HDMI female, and (1) Micro-HDMI “D” to HDMI female. The adapters are molded with a very strong eyelet that attach to the aircraft-grade steel cable. The main clamp is ABS and it can connect to HDMI cables up to 11mm in diameter. Two sets of foam rubber inserts for differing cable sizes are included.
