Model UD-2A-EDID
1.0 General
Thank you for purchasing Hall Research’s UD2A-EDID. This is a
versatile, high performance DVI 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 UD2A-EDID-S memory in the “Emulate
Learned” setting, which allows the unit to act like an actual monitor
connected to the INPUT DVI connector.
The UD2A-EDID-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.

3.0 Installation
3.1 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
3.2 Inputs & Outputs
The UD2A-EDID-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 UD2A-EDID-R has two UTP input ports, a DVI output, audio
output, and RS232 output.
3.3 Connecting the UD2A-EDID-S
Plug in the desired video and audio sources to the INPUT DVI and
INPUT AUD connectors on the back of the UD2A-EDID-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 UD2A-EDID-S (sender) to a UD2A-
EDID-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 UD2A-EDID-S and apply power.

Model UD-2A-EDID
Select the desired EDID routing path using the front panel buttons,
through RS-232 serial commands, or GUI software.
UD2A-EDID Rear Panel
The UD2A-EDID-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.
4.0 Operation
The UD2A-EDID-S allows multiple control methods, such as front-panel
buttons, RS232 serial commands, or GUI software.
4.1 Front Panel Buttons
The EDID ROUTING button is used to select what EDID information
will be sent to the video source when requested. The choices are:
EDID Routin

OUTPUT DVI Connector into the “EMULATE LEARNED” memory and
save it for future use.
Use the EDID ROUTING button and select which device you desire to
LEARN; either the DVI-LOCAL or UTP-REMOTE.
Press the LEARN button for 3 seconds; the EMULATE LEARNED LED
will begin to flash to indicate that LEARN mode is in progress.
When the unit has successfully completed LEARNING the EDID of the
selected device; the UD2A-EDID-S unit will sound 2 short beep tones. A
long tone is sounded to indicate an error occurred.
Programming the EMULATE DEFAULT position can only be done
through serial commands or the GUI software.
The Output Boost buttons are used to enable or disable the DVI output
signal boost.
UD2A-EDID Front Panel
4.2 RS-232
The UD2A-EDID-S can be controlled via a serial device. From the serial
port, you have full control over the operation of the front-panel buttons
plus many more capabilities. Terminal emulator or ASCII software is
required. An example is Microsoft WindowsHyperTerminal (generally
found in the START->Programs->Accessories->Communication folder)
Note on RS-232 port availability on your PC
Most PCs and notebooks do not have a
serial port. So to program the Switch you
may need a USB to RS-232 Serial
converter. These are available from Hall
Research (Model USB-RS232-1).
