About the DP DA2

The DP DA2 provides an Extron distribution ampliﬁer for VESA

DisplayPort signals. It

accepts a single input with data rates up to 10.8 Gbps and, in normal mode, distributes

two identical outputs with resolutions of up to 2560x1600 @ 60 Hz on each output. Input

and output signals can each be carried a maximum of 25feet (7.62 m).

In Extend mode, the DP DA2 outputs an image with a resolution of up to

3840x1080@60Hz extended over two output displays.

The DP DA2 uses the DisplayPort v1.1a standard and is backwards compatible with

earlier speciﬁcations. It has EDID Minder

for EDID management, Key Minder

for

continuous HDCP veriﬁcation, and can be controlled by RS-232, using the Extron Simple

Instruction Set (SIS

™

) commands.

DP DA2 Features

DisplayPort — In normal mode provides two identical outputs with PC resolutions

up to 2560x1600 @ 60 Hz, with multi-channel audio and HDTV up to 1080p @ 60 Hz,

distributed with embedded multi-channel digital audio signals.

Thunderbolt

™

source support (input) — Thunderbolt sources are backward

compatible with the DPDA2 input with respect to both audio and video. Thunderbolt

devices are not supported on the DPDA2 outputs.

Signals up to 10.8 Gbps — Supports data rates of either 1.62Gbps (reduced bit rate)or

2.7 Gbps (high bit rate) using one, two, or four lanes.

Dual mode — Allows for interoperability with HDMI, DVI, and VGA display devices.

Provides connectivity between a dual mode DisplayPort-equipped source and HDMI, DVI,

and VGA display devices with an appropriate adapter.

Extend mode — Outputs a single image with a resolution of up to 3840x1080 @ 60 Hz

extended over two output displays.

EDID Minder

— Maintains continuous EDID (Extended Display Identiﬁcation Data)

communication with the attached source. This ensures that the source powers up

correctly and maintains a proper video output, even if the display is off.

Content protection — Supports High-bandwidth Digital Content Protection (HDCP). The

DPDA2 checks the source and output displays for HDCP compliance.
