1.0 General
Thank you for purchasing Black Box AC1032A-2A 2-Port DVI Switch
with Audio & Serial Control.
This unit provides both a video and audio output that can be switched
between two video and audio sources. This allows routing of multiple
DVI equipped devices (such as PC’s) to a single DVI display (such as
a plasma or LCD screen). The switcher supports single-link, DVI-D
video signals at resolutions up to 1600x1200 and HDTV up to 1080i.
The AC1032A-2A unit provides all the A/V and control connections
on the rear panel; the front panel has a push-button switch with
corresponding LED indicator for the selection of video source. The
front panel also features mode selection buttons to allow the unit to
operate automatically (based on video sync signal detection).
This unit can be controlled by either manually using the front panel
switch, automatically based on video detection, or remotely through an
RS232 serial port.
The unit can be configured to operate in two different modes: Auto and
Manual.
There is a priority selection that can be set for the ‘Input 1’ DVI
connector. The switched output can be blanked and un-blanked either
from the front panel button or from a command sent from a PC to the
serial port.
The unit also has EEPROM (internal non-volatile flash memory) to
store the last operating mode when power is off.
