1. Introduction
General
Thank you for purchasing Black Box Corporation AC2000A. This is a
versatile, high performance DVI, Audio and RS-232 extender with EDID
management.
This unit has the capability to read the EDID (Extended Display
IDentification) information from the device connected to either the DVI
output connector or the receiver connected to the UTP output. This
information can be stored in the AC2000A-S memory in the “Emulate
Learned” setting, which allows the unit to act like an actual monitor
connected to the INPUT DVI connector.
The AC2000A-S has local DVI and remote UTP video and audio outputs.
Its video outputs can be blanked out or boosted when needed. This unit can
drive video, audio, and RS-232 up to 300 feet depending on the video
resolution being displayed.
This unit can be controlled by either manually using the buttons on the front
panel or remotely through a serial port with RS232 commands or GUI
software.
The unit also has internal memory to store the last operating selection when
power is off. The unit allows four different EDID settings to be routed to
the video input device.

2. Installation
2.1 Required Cables
The video cables are DVI male to male. The audio cables are 3.5mm mini-
stereo. When connecting to a PC’s serial port for remote control of the DVI
extender, an RS-232 to PC cable is required (Customer provided). A
detachable 3-terminal mating connector is provided with the unit. The
function of each pin is silkscreened above the 3-terminal input connector on
the rear of the unit. Below is a diagram for connecting this port to a PC’s
DB9 serial port.
RS-232 to PC cable
2.2 Inputs & Outputs
The AC2000A-S has a DVI video input, a mini-stereo audio input, a RS232
terminal block, Local DVI output, Local audio output, and two UTP ports
for video, audio and RS232 extension. Power plug is a standard IEC
connector, (IEC 60320 C14)
The AC2000A-R has two UTP input ports, a DVI output, audio output, and
RS232 output.
2.3 Connecting the AC2000A-S
Plug in the desired video and audio sources to the INPUT DVI and INPUT
AUD connectors on the back of the AC2000A-S.
Connect local video and audio devices; such as a monitor to the OUTPUT
DVI and AUD connectors if desired. For remote video and audio; two
CAT5 cables are used to connect AC2000A-S (sender) to an AC2000A-R
(receiver) through UTP Extension port LINK A and LINK B connectors.
NOTE
Do not cross the A & B Link cables when connecting to the receiver unit.
Failure to observe this precaution could result in damage to the unit
Connect the RS-232 to PC cable if remote serial control is desired.
Connect the included power cord to the AC2000A-S and apply power.
Select the desired EDID routing path using the front panel buttons, through
RS-232 serial commands, or GUI software.

The AC2000A-R does not require a separate power supply; the power is
supplied by the sender unit via the UTP cabling. Be sure to connect A and
B link cables correctly! The Green PWR LED will indicate when the
cables are correctly configured. Once the cabling is correctly connected,
attach a monitor to the receiver DVI VIDEO OUTPUT connector. Connect
the remote audio device to the STEREO AUDIO 3.5 mm jack, and a RS232
device to the 3 pin RS-232 connector; if desired.
