Adder DVA Manual

							Welcome
The Adder DVA (Digital Video Adapter) module converts analogue (VGA) video into digital video 
conforming to the DVI 1.0 standard. Installation is quick and easy: The Adder DVA attaches to the 
analogue video output port on your computer and gains its power from a spare USB port. You then 
connect your DVI video display to the digital video output port on the DVA module - and that’s it. No 
special drivers are required and operation is totally transparent to the devices and to you, the user. 
The Adder DVA can support the majority of video modes defined by VESA DMT with vertical refresh 
rates of between 56Hz and 75Hz up to 1920 x 1200 @ 60Hz (reduced blanking). Refresh rates of 
85Hz and 120Hz are not supported.

Radio Frequency Energy
All interface cables used with this equipment must be shielded in order to maintain compliance 
with radio frequency energy emission regulations and ensure a suitably high level of immunity to 
electromagnetic disturbances.
European EMC directive 2004/108/EC
This equipment has been tested and found to comply with the limits for a class A computing 
device in accordance with the specifications in the European standard EN55022. These limits 
are designed to provide reasonable protection against harmful interference. This equipment 
generates, uses and can radiate radio frequency energy and if not installed and used in accordance with 
the instructions may cause harmful interference to radio or television reception. However, there is no 
guarantee that harmful interference will not occur in a particular installation. If this equipment does 
cause interference to radio or television reception, which can be determined by turning the equipment 
on and off, the user is encouraged to correct the interference with one or more of the following 
measures: (a) Reorient or relocate the receiving antenna. (b) Increase the separation between the 
equipment and the receiver. (c) Connect the equipment to an outlet on a circuit different from that to 
which the receiver is connected. (d) Consult the supplier or an experienced radio/TV technician for 
help. 
FCC Compliance Statement (United States)
This equipment generates, uses and can radiate radio frequency energy and if not installed and used 
properly, that is, in strict accordance with the manufacturer’s instructions, may cause interference to 
radio communication. It has been tested and found to comply with the limits for a class A computing 
device in accordance with the specifications in Subpart J of part 15 of FCC rules, which are designed 
to provide reasonable protection against such interference when the equipment is operated in a 
commercial environment. Operation of this equipment in a residential area may cause interference, in 
which case the user at his own expense will be required to take whatever measures may be necessary 
to correct the interference. Changes or modifications not expressly approved by the manufacturer 
could void the user’s authority to operate the equipment.
Canadian Department of Communications RFI statement
This equipment does not exceed the class A limits for radio noise emissions from digital apparatus set 
out in the radio interference regulations of the Canadian Department of Communications.

DVI output to video display
Optionally using the USB socket
If required, you can plug a USB peripheral, such as a mouse or keyboard, into 
the spare USB socket on the DVA. However, ensure that the peripheral does 
not draw more current than 100mA, otherwise the operation of the DVA 
module could be affected.  
From USB peripheral
The Adder DVA requires no drivers or special 
settings to operate; simply plug and play.
Upgrade and reset modes
Note:  When the DVA is in upgrade mode, the video going through it is disabled, so you are recommended to connect it to a USB port on a different PC. On the side of 
the DVA module, you will find a small hole and a recessed indicator. These are used to invoke special functions. Use a thin implement, such as a straightened 
paperclip to press and hold the button concealed behind the smaller hole. Depending on when you release the button, the module will either perform a 
normal reset, enter upgrade mode or completely reset itself to factory defaults:
Time (in seconds):  0  .   .  .  .  5  .   .  .  .  10  .   .  .  .  15  .   .  .

Release button     Normal reset       Enter upgrade mode        Reset to factory defaults    Normal reset
The DVA will report itself as a USB memory stick labelled ‘Firmware’. The upgrade file is a binary file that you drag and drop into the DVA’s ‘Firmware’ entry within your 
computer’s file manager; whereupon the file transfer process will commence. Once the file transfer has completed, the DVA needs to be rebooted by either pressing the 
reset button again to bring it out of upgrade mode or alternatively the USB lead can be disconnected and reconnected. The current firmware version can be determined using 
the Adder VCP app (a Windows app available for download from www.adder.com).
Use paperclip to press and hold the buttonIndicator
Note: The Adder DVA can be connected into 
a USB 3.0 connector as well as the 
standard USB 2.0 connector. 
However, there is no USB 
3.0 operation, the 
USB feed through 
runs at USB 2.0 
HS data rates.
